Is it right to call a gambling platform a scam for confiscating users account with the deposited balance because you use more than one SIM card to access the platform? The SIM cards aren't from same network provider, so their IP addresses are different from one another.

This happened to someone I know very well, but I found this to be too cruel,  different IPs on the same device shouldn't cause this ban, what do you think?  

There are some gambling platforms that pray that users make this mistake and use the opportunity to sit down on their money.

I am pretty sure that must be a really bad casino platform to play on.Most of well reputable casinos always send me an email letting me know that I started a session on their website and I am in the same country but I use different ISP-s and they know that it is me,I also have 2FA enabled and when a person has 2FA enabled means that 99.99% is this very same person accessing the casino so yes based on how you describe the situation,this is extremely cruel and the name of that platform should be made public so everybody is aware of such scammy platforms.That is why I have said here at least a hundred times that people should check this very section we are writing here and check the ANN thread of reputable casinos and only play there,this way such incidents won't happen again.

If there is a suspect of multiple accounting from the same user the highest the casino will request from the player is KYC, and this is one of the major reasons why the casino has KYC policies on the ground.

-And any casino that confiscates your balance without due process must be a scam casino, and we have many of them so you are warned to avoid using such a platform.

Which casinos you are talking about, I think you should mention it so members will not make will guess and starting to worry about such case?
I'm pretty sure my IP is always changing most of the time since I use several different internet providers but I have never experienced something like that in some different casinos.
It would be better if you can also provide evidence for the case, if you dont, others may say that you are spreading FUD or hoax here.

I definitely agree with you- there is a boundary between a complete deprivation of funds without any notice; and a casino who has strict T&Cs who implements it with great stringent requirements. This gambling company is the former- they tend to completely confiscate the funds without any notice due to some minor problem that can easily be fixed on their end.

Since this is the case, better yet avoid this online casino completely. To be honest, I am more inclined to convince you to spill the name of this casino so that everyone in this forum would be alerted and notified to avoid this completely.

If we are to look into your case well, what i can deduce is that you're trying to use ip address embargo to waive some certain restriction in which later turn casted, this is your own fault and bot theirs,how you consider a number of gamblers that would have been launching attacks on several occasions using different means to byepass their system security, but because some casinos were also at very good alert they create a resistant against such, i wouldn't blame them because they would have gone bankrupt if careful measures aren't taken against the abusers of their casino.

If both accounts are used at the same time, I think that would be suspicious.  
You would just continue betting without reading the emails and ignoring the notifications on your casino account but if you suddenly get limited access to the funds, you would be alarmed that's for sure. And that's when you need to take action.

But if you didn't do something weird I think you will be fine with multiple accounts. I've tried it but only because the first account I have was using a throw way email and I can't remember its password anymore. My funds weren't locked.

It will still fall under multiple accounting, so I don't find it harsh if the user is reprimanded like this. Different sim cards and different IP address is one way of trying to game the system and going against the platform's ToS. This is just the casino enforcing their rules against the user, and it's up to your friend whether he'll abide by those or not. He's caught, he's reprimanded, and he's taken off his balance. For all the casino knows, your friend could have been doing this for a while and have gained considerable advantage against the casino leading them to lose money, so I think it's just a fair judgment on the casinos end--that is if what they did is fair, of course.

I think is not gonna to be problem, as long you're on the same country IPS.

Let's say, you're from Country A and suddenly there has some change activity to Country B. IMO, it's only a security feature to allert the user there has some unknown activity in your account.

I believe not only casino can do that, but also all other financial service.

While I don't see it as a problem to consider by some gambling sites, regarding the use of a different network SIM nor having the same located IP, are you sure OP that's the only reason why the account got close to the point that funds are confiscated?

Technically, that was harsh as for funds to be confiscated, the violation should be really considered heavy.

Is this a true story OP? If yes, what site is this? Or just sharing a scenario that might happen to some users?

No, I will not support the platform decision in this case. It's normal you will have two sim cards in your mobile. You will use both sim Data to browse the internet. But the platform can not ban for this reason only. I don't know yet even if there could be rules like you can not access sites from different IPs (even the device is the same here). But if there is any TOS like this they can take this decision but it's against the users. Not a good decision and this could not be a good platform.

I think its completely ok to have 2 different sim cards and/or IPs. You could have as many IP's as you want and the casino should have no grounds of taking away your money. Although they would have grounds on suspecting you of multiaccounting or some other rule breaking. In that case they would withhold your withdrawals until you did a KYC. After which they should unlock the funds and let you withdraw.

If they keep it after you KYC then the casino is probably a scam website.

Although if you KYC from a country forbidden by terms and services then you might still be in trouble. But by law they would have to refund you your betted money while confiscating winnings. At least that is how it works from what I know.

Depends on the casino rules you mean.
Actually using different IP with the same device is like using multiple accounts.
Because what detects all of that is the system and maybe the system detects what you are doing as cheating.
I understand what you're saying but still it is the policy of the casino to confiscate funds and possibly freeze them if a fraud is suspected.
But I think why are you using the same device ? whereas you should already understand that such behavior is against casino rules and puts your account and balance at risk.

More details are needed. Did your friend use the platform with a same account through 2 different SIM cards, or was he multiaccounting the platform? If so, why was that necessary? It might have indeed raised suspicions on the platform operators' side.

However, the procedure isn't correct without asking for KYC first. The website should have given him the opportunity to show the documents to prove he wasn't cheating the house.

Or maybe the casino did this before finally seizing the funds? It's really hard to talk about something when a lot of essential informations are missing.

Every system takes a major priority to it's security apparatus and possibly takes or go hard on anything that appears to be a threat to it's security. And the Said gambling platform must have taken such a swift action to be on the safe side. So we can't just jump into conclusion declaring the process that led to the circumstance as a scam. There are T/C's laid down by every gaming platform as to the do's and don't of it's customers but usually mist customer's don't interest themselves in getting acquainted to them not until they err these terms and ignorantly raise a scam alarm.
Am sure there should be an open means your friend or the person you talking about can use to lay a complaint to their customer service and provide the necessary details they may require  to exhume his account and show prove to his claims.

This is too cruel and I likely will consider such a casino to be a scam casino, accessing a casino from different IPs isn't a reason enough to block a user and confiscate their fund, it is only a scam casino that will do such a thing.

There are several instances where a gambler could run out of internet data, and ask his or her friend to share him or her internet data through Hotspot to complete or bet or check on  his or her bet, in this process, it is evident that the ip used will change from the initial one, does it mean that doing a thing like this is now a crime??

That casino is a pure scam, except there is any other offence the guy in question committed to warrant the casino to confiscate his funds, but if there isn't, then that casino is simply a scam casino.

I played (and still play) in some casinos from several IP addresses. I play mostly from home (1 IP), sometimes I use mobile internet (2 IP), and when I hang out with kids at parent's house I use their WiFi (3 IP address). I just log in and I play without any problems... without KYC after years of actively playing in those casinos.

So from my experience, I doubt that any player will be sanctioned just because he used different IP for the same account (the same device or not is even more ridiculous, I gamble from a laptop and mobile phone in the same casinos from different IP addresses, and in few occasions, I used my wife laptop...). So there's something more, it's not just about different IPs! Maybe OP's friend tried to create multiple accounts and abuse some free drops and bonuses... that happens more often than we think.

Something very bad. Things that shouldn't be a problem but are a problem.
This case is pure fraud perpetrated by a gambling platform.

A player is not very good at keeping funds in the balance of a gambling site because it contains a big risk. One of the risks is like this case.
Another thing that a player needs to consider is choosing a clear gambling site before making a decision to register.

At the same time it's important for gambling platforms to have rules and policies that prohibit the use of multiple accounts or devices to access their services and these rules are typically put in place to prevent fraud, money laundering, and other forms of abuse and user protection. In this case you are talking about there is some users that get hacked and access to their account so it's important for the casino to stop that hacker from withdrawing and even gamble which may lead to big losses.
But trusted and legit casinos of course they will only apply the ban and restriction for a limited time until they verify that everything is good by uploading and confirming identity. If not than the casino is just a scam simply

Casinos have no right to confiscate our balance since it’s clearly against our privacy, and I think reputable casinos know their limits so they will never do that. But for scam casinos, knowing they will do everything just to take advantage over our money, then maybe they eventually do that and just point out some mistake on the casino user itself so that the casino will never be liable and will never be at fault in the end. Obviously, it’s another trap for scam casinos and if you gamble without small knowledge in gambling, you will definitely fall for it.

It depends on what is stated in their Terms and Service. If such a case can lead a user account to be put on ban, no choice but to accept the terms. However, that should be clearly detailed to all parties. However, if we take a look at that case that can lead to confiscating the user's deposited balanced, it does not seem fair.

Aside from that, with that simple situation you have mentioned, it should not lead to banhammer and confiscation of the money right away. Maybe there are other parts of the story that you didn't know and just stated the thing you understand well.

Is this for real? Is there really a case like that happened?

This is the first time I heard of a case where a casino confiscated a fund because it uses different sim card to access the platform.  Using different sim cards of  a same country should show the same region, besides, it is not a multi-accounting but rather having different IP of the same country to access the platform.

I have no idea what would be the violation of this kind of action, if the country or region of your friend is not restricted, I don't see any ground for that casino to confiscate the fund.  I think there is something that you're friend is not telling you.  But assuming your friend is telling the truth then I would think that the gambling platform is at fault here.  


I have never seen any rules about using multiple gadgets to be restricted in any gambling platform.  More or less the @OP's friend might be charged of multi-accounting because of the sim card IP being shared by different users.

No, it doesn't have to be that way; in fact, many providers and cellular carriers provide their users with a dynamic IP.
Maybe this user has whitelisted IP addresses? In this case, there may indeed be problems with access to the site.

I don't think you are 100%  right on that statement about the right of casinos to withheld withdrawal or balance because according to the anti-money laundering laws it stated that your account will be restricted until you can provide valid means of verification of the ownership of the account.

-I may not be right in all cases but there are quite a good number of casinos that have that mentioned in their terms of service and players need to agree to that before account creation.

Sounds a bit extreme, many IP are dynamic anyway.  I understand sometimes KYC might be requested to verify a unique account.   In majority of cases people should be allowed to close out in an orderly way but its true sometimes actions are required to prevent fraud or especially misuse of bonuses.  Hard to say in absolute way either extreme is correct.

I also find this story quite exaggerating but if this is really happening, then it’s obvious that your violation on their rules is heavy and you need to be reprimanded from it. However, whatever the level of your violation is, still they have no right to confiscate your funds since it’s already unethical. They can banned you as long as they want, but confiscating your funds, only scam casinos do that.

Two different IPs should not cause the ban. Usually, a platform will send out email to validate the new IP as it is seen as a security threat to the user's account. So to protect the user's fund, they ideally send email to validate the user and once the validation is done, everything should be normal! That's the usual practice!

But please try to understand more about the situation. Because the scenario you have posted should not cause a complete ban especially when you have funds in your account. The gambling platform should give the user another chance to release the funds. If they have not given the chance to withdraw the fund through KYC or other verification, then open a thread in the scam acquisition forum to report the platform. We are interested in knowing the name!

Definitely a bad attitude towards clients, sounds like they are preparing for further addition of KYC, if not yet done... However, most security algorithms see several different ips in one session as an attempt to break into the account... So, I think that stable ip is a must have, especially for gambling

Are you maybe referring to an issue with Metaspins?
https://bitcointalk.org/index.php?topic=5444025.0

In this case OP did not admit to having 2 cards. OP claimed to have only 1 account and there was no proof provided by the casino. The player also went through KYC and despite that was denied all funds.


I agree with this. KYC should always clear things up.
There's also many ways to handle a user with 2 accounts from being extremely nice to him and asking him to choose 1 account and transfer all funds out of the other because it will be closed, through denying him wins on one account, through denying him wins on both accounts, up to a blatant scam IMO, which is taking his wins from both accounts along with all deposits.

Depends on the policy of the casino so always read the TOS since if they right that they can seize the money of the user proven to use multiple account then there's nothing you can do with it if the person you know been using that on that casino. But this is really harsh way done by them since the really proper way to this approach is return the funds of the user then block their account.

Maybe that is very shady casino which always think about their gains so better leave that if you know they are doing this actions.

I don't think casinos will be that nice to ask a user to choose between accounts when caught in case of multiple accounts since most of them already have it mentioned in the T&C of what penalty they will issue if a player is involved in multiple accounting.

-Since casinos are out to do business,  once they discover any issues related to cheating the account is outrightly flagged and close pending when the case gets cleared up or forgotten.

This is hard to believe and it would be nice to know what casino did this.

Some casinos don't allow VPN, but since we are talking about SIM connection, then the IP should be from the same region. And this scenario could be the same as a user with a dynamic IP, that's why is hard to believe.

Even if the casino detects multiple log-in on the same account at the same time with different IP's that's not enough reason to block the account because that could mean the user is connected from PC and Phone at the same time.

Any platform that is going against our own privacy and is harming our funds, I know in the first place those platforms are not safe and reliable. So once you experienced it, then stay away from that platform by then because obviously, they are here to scam people and not to treat them the right way. And I don’t think using dual sim with same device is a big offense for them, if their goal is to scam us, they will always pushed through it.

That's why I wrote "extremely nice" which implies far above average response. I wouldn't expect that, but I also believe that this should be decided on a case by case basis.
Imagine that someone made 2 accounts, got no warning upon registering because the system did not detect it, deposited only on one of them and played on 1, until he got caught. He did no damage to the casino, did not influence other games, did not cheat. I see no reason to ban or deny him his win on that 1 account that he used.
As a representative, I'd ban the unused account and let the player know why it got banned, that's all.

Please give us clear and more detailed information. Changing SIMS shouldn't have that kind of related penalty. I don't even consider that as a way or attempt to do some cheating on the gambling site. There must be other IP-related issues that your friend went through.

Besides, if your story is true, why not just mentioned the site you are talking about for us to make a self-research?

If that is legit though, that is a harsh thing to do by the gambling site and unprofessional to have that kind of treatment to their customers.

It can be clear that his friend didn't read the rules or the casinos terms and conditions before using the site and thinks that such acts is allowed but it was too late already. The unexpected have already happened but this should teach his friend a valuable lesson and that is like I said earlier to not be lazy but always learn to how to read guidelines. We can't call this cruelty.

The casino is not harsh. Sorry to say but it looks like the OP is and his friend is the one that is harsh here because they came up with these accusations or complaints. The reason on why his friends did that can be valid and not for abusive purposes but rules are rules and there might no be excuses for it.

It's totally fine to disable users account if caught violating against TOS like having multiple accounts and proven that it's owned by a single user. But about the funds on those accounts and its balances, the casino should release them and not take any single penny from them. Review their TOS if disabling accounts include taking their customers fund and removing their access forever. Because AFAIK, if they will ban you forever, you'll be allowed to withdraw at a given time before you'll have no access anymore on them.

It's considered harsh for me while at the same, a crappy treatmentt of that site. Since when a user's deposited balance should be confiscated for that kind of reason? But can you share what site is it so we might take a look at their TOS? Maybe it was really your friends' fault but funds shouldn't be confiscated.

Hard to judge a book by its cover as what we only read is your side.

We should make it balanced and know the real story here to be fair in all concerns.

Is the casino really one of the trusted ones here although it is most likely not because I gambled at several trusted casinos on this forum all smoothly even with the change of driver's license.
The confiscation of the balance because of trivial things like this is definitely one of the problems and the possibility of the casino is a scam I think. and of course leaving from there is the right thing even if your balance is still there. Although the hope is obviously that it should be returned first but if the worst case scenario is not possible then leave immediately.

wondering if that was the reason given by the site why they confiscated the funds? because from the OP's statements, it seems, they are concluding the reason why the site confiscated the funds. because logging in with different IP should not be a problem because most people are using internet service providers with dynamic IPs. not very many have their static IPs at home. and a lot of smartphones nowadays have dual sim capabilities. maybe there's more story on this situation...

I also think that different IP on the same device shoulnd' caused a ban unless the gambling platform prohibit VPN.  But in your friends case, I bet the IP is in the same country since it is just a different sim under one country?

It is also possible that one of the IP used by your friend was been recorded to be used by other player who exploits the gambling platform.  Since I read that

So it is possible that the gambling provider "mistakenly" tagged your friends account as another people's multi- account.  The reason for banning and confiscating funds. 

Btw, did your friend appeal or contact the gambling platform why his account fund was confiscated?

If its just one account and you’re using multiple IP address, there should be no issue with that. Imagine, gambling everywhere and you are using a different wifi connection, that could be more reasonable.

Also, using multiple device is also ok as long as you will not use it to login different user, some gamblers have their own phones, tablets and pc, so there should be no issue with that. Maybe they can investigate your account but they still have to release your money because you are doing fine with your one account only.

Op I am trying to suspect something fishy in you, because all you thread that you have created in this gambling board are for you friends and someone you know. Even the casino website you wanted to launch was for someone then what is that thing that is for you in the forum. Are you always typing or posting for someone?

By the way how the confiscating started, did they tell you anything before starting the confiscation? Before you call the scam, you have to hear from them to know the reason. By the right they are not supposed ban or block you because you use two SIM card to visit the site. Because network might disturb in one sim and you might decided to use the other sim to do what you wanted to do so banning you because of the switch of sim card is wrong.

Review their terms of service and if its really now allowed in the first place then I think you’ll be in trouble.
Some site are not that strict since technically, having multiple IP address doesn’t necessary mean you have multiple account when in fact you are just using one account its just that you have to use different connections to further improve your gaming experience.

Anyway, better to disclose the site we are talking about here and see if they really have this terms on their site.

They will surely ask for an enhanced verification which means a higher level of KYC procedure.
It could be a video document that proves your identity and your place at the same time with other accounts that suspected your alternate account. Sometimes we think that a casino has this loophole and a way of scamming people, but if you know how to deal with it there is no problem --if there is, that is a scam casino we could not change that behavior.

That action could be a red flag to a specific site so having this enhanced KYC is necessary just to protect the interest of both parties.
You should not be intimidated by this if you are not doing anything illegal, and you can explain your side to them since having multiple IP address are common if you are using different connections. I just don't understand to the word confiscating, is your friend OP can't access his account anymore?

I think we are not talking about confiscation of funds, but about freezing the withdrawal of funds.
If the user really had funds confiscated just because of different IP addresses, then it is definitely a fraud.

It is not right but it will trigger an alarm of a possible double account because the system thinks that two people are using one account on their platform

The information you provided is not complete did the casino ask for KYC and did he fail the KYC they will ask this before taking drastic action like this.

There are good and bad casinos and there are casinos that ban you when you're continuously winning these bad casinos only want gamblers who deposit a big amount of money and lose it.

This is very sad and I truly understand how fustrating and annoying this very act could be but I don't think it is wise for a casino to block and seize someone's money just bevaue a different sim was used or different IP was used because I believe the KYC should be triggered and the user be asked to provide KYC rather than blocking someone's account.

I think you should mention the name of that Casino so as to help safe other users from falling orey to them and I think this casinos really need to be reviewed and licenses shouldn't just be handled over to persons who have the money to run a casino but rather a proper research ought to be made about the management team before issuing certificates of operation to them.
You should make a post or report in the scam accusations thread and also on the casino's Ann thread if they're present on the forum.

This is not supposed to be so, I saw this as a harsh attempt by the casinos confiscating users account. I know that there are many casinos that do kick against this kind of act but not when the IP address is not the same. At least the casinos should have consider the user for some reason not just confiscating the funds inside the account. Some of the reason why this can happen is when the casino had onced face multiple casinos of users creating different account and using them to makeomey from the casi6in an unfair manner.

No matter how hard the casino tries to stop people from carrying out criminal acts on their sites, the more the innocent suffers. I so understand that a casino already a has a certain rule or terms of operation, but blocking an account without sending out notification or refunding the capital shouldn't be taken lightly as acts like this are mostly suffered by innocent ones. I think kyc ought to address the case of multiple accounts without having to cause any pains on your workers.

I think the OP needs to tell us sincerely If the account was suspended and kyc was  triggered because I'm sure if the account was frozen due suspicious act of a different IP login then it will released after proving ownership of the  account, but if not then it's a scam and should be treated as such.

This doesn't make any sense. Do you have more information? Did your friend use 2 different accounts or just 2 different sim cards? Because using 2 different sim cards / internet service providers shouldn't be a problem unless they overlap somehow that 2 different users have been using them. And even that can be talked out with the customer service if there are clearly 2 different ids and proof of that.

Maybe this should flag a user for KYC or something. Personally I think you would be opening a can of worms for the casino and abusers would chime in crying they used different sim cards, they didn't make multiple accounts. Casinos could also make a decision on a case by case basis. If there is no bonus abuse or whatnot, then maybe let it be.

Basing up with my own experience which i do make use of different sim cards on different gambling platform then its just fine or even on using up on the different sim cards but registering on the same device which it

is really still that fine.So it would be better if the site or platforms name should really be that mentioned so that people would be aware if ever there are players who are doing this behavior.
I do partly agree on that saying about being having finding ways for some violation even on the slightest on making peoples locked up and confiscate their funds due to some violation.
Some might be honest and some are really just that alibis.Therefore, it would be always recommended on dealing with legit and reputable sites which does have less issues.

Let your friend create a ticket and present his/her case. But I don't think this is enough basis to label the casino scam. In the first place, casinos are also protecting themselves from possible abuses. Multi-accounting, for example, is normally not allowed. They install mechanisms that get triggered once they detect a suspicious activity. And I suspect that your friend's changing of network is a trigger. But let your friend contact the support first and explain his/her side in detail.

The problem is that casinos sometimes tend to overreact. Or perhaps it's just what they have to do to protect their platform. Two gamblers with separate accounts sharing the same house could also set a casino's alarm.

Using another IP could be enough of a reason to close the account but it should be fine unless you're using an IP from another country to bypass their geo-restriction.

There has to be another reason why the casino confiscated your friend's deposit but if they're the ones who stated that the sim is the issue then yes it's definitely harsh as other casinos would be willing to return the user's money.

Here I will emphasize a little that what you have said is actually still not quite right because every casino will definitely not let their customers always win in betting or games. After all, casinos are a profitable business so casinos have their own way of being able to give victory also would give their customers a lot to lose for the casinos to take advantage of gamblers. Good or bad casinos are not about casinos that will take advantage of the money gamblers deposit but in terms of trust whether a casino can be trusted and guarantees the security of funds stored by customers in casino wallets.
I think it's only natural that casinos don't give their customers big wins because they set up casinos to do business and get a big profit.
So we all have to be wiser in responding and concluding all assumptions about crypto casinos and about the gambling industry.

I don't think the casino will confiscate the user fund and there's no way to solve it, most of casino will ask to submit KYC when there's a user breach their terms of service. It's better if your friend or you create a scam accusation thread about the casino, because we don't know what's the casino you're pointing above. The change of SIM card isn't a big deal, it's not like the user is cheat about the game or betting for taking advantage.

This is the very first time I have heard of something like this, unless they had evidence that your friend was abusing their website and he had several accounts then this seems a little bit too extreme, as who has not accessed their favorite gambling website from a different device? At this point I cannot help to think that the casino you are talking about was just looking for a way to refuse to pay and they used this as an excuse.

What’s the problem with multiple ips? So the user isn’t allowed to change his sim card ? What kind of rules is this? I know casinos have problems when you have single ip and multiple accounts connecting from it, but here the case is different and complete opposite. So the casino doesn’t have any right to confiscate the balance. OP if you don’t mind then please mention the details of the casino. Also as from these types of rules, it’s completely concluded that the casino is new and not trusted yet. So it’s better to avoid these type of casinos if you love your hard earned money.

I don't think that would apply to a reputable casino because they can tell where their users are coming from. I've read that one casino only requires a one-time visit from a user using their original IP. After that, users can use any IP because the casino records each user's IP address and connection details. It looks better, doesn't it? Because we don't need to bother thinking about whether it's VPN or using a different SIM card.

But as long as I play gambling, I have never encountered anything like that so I don't know if there is a casino that applies that way. It may be worth asking the casino's customer service and asking them for an explanation.

It's pretty weird, though, if you change your internet connection. I mean, when you play in your house, you are using wifi, but when you go outside, you either connect to other wifi or use data, which means your IP will change, so there would be a lot of people getting banned on this. If the casino is legit, there is another reason for it: multiple accounts. As you know, this is one of the most prohibited things to do, and if it is stated in their terms and conditions that they will confiscate the balance, then we have no choice.

confiscating the deposit balance for the reason of having a different IP address the user usually have is BS. I wonder if there is more gambler out there that used their gambling site and got banned because they used different IP addresses when using their account.

just curious, what's the name of the gambling site the person you know is using? I am curious because that gambling site should be avoided.

balance confiscation from customer just because of IP problem, there used to be this kind of problem but that person use same IP in same device after that create more than one account. I agree with @panjul07 statement, if you (OP) really have problems at the casino confiscating your balance, please provide evidence at which casino you registered or made a deposit after that your funds were confiscated?

i have a slight suspicion, could it be that the OP made multiple accounts at one casino causing balance confiscation. because it is very rare for balances to be confiscated due to IP reasons like that.

If it is inside the casino ToS, It is justifiable but if it's not indicated I think it can be contested. Most of the time, This kind of case is connected to multiple account issue. Though I believe that you won't be banned on using different sim cards or different devices on a single account. The IP we have on sim cards is AFAIK have a dynamic IP and using different devices that has no history of other account logins should be safe. Multiple devices with static or a dynamic IP on one account is safe, but using a multiple account on a multiple devices even if it's a dynamic IP is considered multi accounting and you could be banned for it. 

If you are confident that you are not using multiple account, and you receive allegation like this on a casino. You can contest it and for sure majority of people who see it will support you.

I also really don't agree that deposit money is also frozen, but that doesn't mean that this casino can also be called a scam, because what gamblers need to know is before playing, read the terms and conditions of the casino so that there are no cases of frozen user accounts and money.

if there really is a case of the same IP or device and they are caught cheating, for example taking advantage of bonuses, their deposit money should not be frozen, just enough money from the winnings, after that the IP and username associated with it are blacklisted, sometimes if you use a SIM card from the internet, a cell phone with the same provider often gets the same IP so it's best to play using WIFI internet, not all casinos are harsh on users it's just that most are like that.  ;)

In fact, of course it should be that way, but many online casinos in their TaC prescribe that it is legal to use only one ip address from one location (family) or only one device per user. But will it be considered a violation if one user uses both a desktop computer and, for example, a tablet or a mobile phone to log into his account, I think all this will be interpreted by the online casino in his favor and consider that the user has violated the rules.

I think that in online gambling you should follow the rule as in trading, that is, have a separate computer or laptop for this purpose and preferably with a white dedicated ip.

I don't understand what the sim card has to do with gambling in a casino. Is it because of the confiscation of the account that you are saying that this is the one that suddenly locked or blocked the account despite a large amount of your balance on their casino platform?

Then I don't think I've seen any crypto gambling that requires a sim card number when you create an account on their platform so you can gamble. is there

There’s no such thing written on any casino ToS that restrict user to play on different IP. The only problem you will encounter if you use an IP that was previously use by other player in the same casino due to multiple account violations. You friend can file a complaint about this on the casino license provider because there’s clearly no violation done on your friend part.

I’m just wondering if your friend is telling the truth for using 2 IP on same account because probably he is doing a multiple account. There’s no recorded case like this here in the forum.

This is so gross, so many nonsense casinos, they should be tried for this. In this present dispensation, casinos should know how things work around the world, even without you changing your sim, most people in the world are using dynamic IPs, so they will seize all their monies because of that?

Well, this is why I like to double-check before entrusting my money to any company, some of them are crooks/rogues that are just using casinos to scam people.

Here OP means that SIM cards of different providers will have a different range of ip addresses used and due to the restrictions of the rules of online gambling platforms for changing ip, the user may be blocked for using different IP addresses for one account.

Well, it depends on what the Alt accounts are being used for....

Some people use those accounts to get some extra gambling money from referral accounts (Depositing on referrals and getting the commission on the main account) or it is used for Bonus abuse.

The severity of the transgression of the Alt account abuse have to be taken into consideration, but in most cases the casinos will use the multiple account abuse as an excuse not to payout the wins.  ::)

Multiple account is not tolerated on the casino and it’s punishable by banning the other account. There’s an exemption if the other account is already inactive since the casino will just delete the inactive and leave the active account unharmed.

In this case, there’s no multiple account being mention. Only two sim cards on one device and one account. This will result to 2 unique IP address on a single account which is not against the casino.

A cheater won't always admit it, until they are caught redhanded with good proof. Your friend or whoever they are may be telling you half the truth. It is wrong to use two IP addresses on a gambling platform and can be considered cheating on the platform. The fault is with your friend. When using a gambling platform, you must follow the rules, and you shouldn't swap your sim card, why not stick with one?

Multiple IPs on a single device/account is not bannable. I haven't witnessed any casino ban users due to that. Can you tell us more about that story of your friend?
You cannot be banned from that, but if he used those IPs with other account, or other accounts had that same IP for relevant reason, then the accounts are subjected for breaking their ToS. But that should be resolved through KYC for both accounts.

I find this hard to believe. Mobile isps have different ip each time you turn on Internet.

Did your friend confirmed with casino rep that different ip was cause of ban? On which casino did this happen?

Well they can prove that they are not using multi account by submitting a KYC to them, by this way they can prove their innocence towards the accusation of the casino to them. For sure the details written upon registration is big help for them to clear out this case. But if the casino still avoid and return their money then this indicate that they are scam and possibly they do this to other user to.

I think that if the rule is one account per person and there's a solid proof that he had more than one account, even with the use of 2 different numbers, the casino should proceed with KYC of both accounts.

If the user cannot do KYC on both accounts or provides the same information for both, his accounts can be banned. He knew what he was doing when he registered the second account, right?

Of course I'm against taking player's money. His deposits should always be returned to him.

In this case, I suspect his friend used different IP addresses to access his account, which raised suspicions from the casino, stating that multiple accounts accessed the account. Maybe it's true that his friend needs to ask customer service directly and explain the problem in more detail so that his friend can solve the case immediately. I think casinos can recognize the IP of a device we use, and if we don't cheat, our account will also be fine accessing the casino.

So, wait, what's the situation we're discussing? Did someone get banned from the casino and have their money taken away for breaking the terms of use? If that's the case, I don't think it's a scam. The casino has the right to protect themselves against people who try to cheat the system by having multiple accounts. They gotta do what they gotta do to prevent fraud.

it is so cruel, the gambling site shouldn't see on one side case and judge the user trying to cheat a game. If they are professionals, they will look it again and try to resolve the problem by deliberation. If they try to make money with that way, I think you must inform us and give the detil what site is?. It's dangerous, because in a developed country, usually people always change their SIM cards because have a limited time if not recharged.

It depends on the rules. If different IPs were allowed BUT the same users aren't, then even with a bunch of IPs you have that you can use, it's still against their TOS. It doesn't matter that it "looks" cruel or harsh, we aren't discussing empathy here, we're discussing how a user simply has to follow the rules of the platform they're registering up for, regardless of what kind of platform it is. If you want to use their platform, follow the rules that they set, simple as that. Now the level of punishment depends on the casino themselves, but that's another point, either way, they'd still be punished.

I have not encountered this type of case once in my years of using online casinos, and it seems to me like a unique case. And it will be too quick to jump to conclusions by calling the casino a fraud. It is possible that this is just a security feature in the casino that was automatically triggered to prevent unauthorized access to sensitive customer information and, by extension, identity fraud. In my estimation, this is where the advantages of KYC for online casinos come into play. If your friend had provided some information needed during sign up, maybe this would have been easy to resolve, as he or she would have had to contact the customer service representative and provide the necessary details or information when requested.

This is really not fair to close a gambling account on this basis. Even you use a same sim card, you will always get a different IP address, each time you connect it to the internet. Of course we do not have a dedicated IP address internet connect as it is not required by home users and also it is expensive.

Since scam casino main target is to get hold of user funds and they make excuses like this as mentioned by you to get the funds and block the account.  :(

I don't think it's fair to ban and consfiscate your balance for this reason since you're not multi accounting (they can ask for KYC to prove it's the same person to clear things out). But it doesn't mean the casino is already scam because it depends on what's written on their TOS if this kind of scenario is allowed or not. The reason why it's important for us to read their TOS before starting to use the platform to become aware of the do's and don't.

But it is scam if casino just made such decision without investigation because these situations are likely to happen to any gamblers using different ips in same device with his only account. BTW, Can you tell us the name of the casino?

Just explain your issue to the customer support of that gambling platform. If you can prove to them that you are a single user with two different IPs and they unblock your account, they are not a scam. If they keep insisting that you violated their Terms of Service and refuse to unblock your account and return your funds, they are definitely suspicious. I don't get why an online casino would block a user with IP addresses to login to his account with each one of his two IP addresses. The user can simply perform KYC verification, when he withdraws his money, in order to prove that he is legit and nobody hacked his account. Let's wait and see how this casino's customer support will react.

I don't think this is right and your friend should challenge that decision. In my opinion a casino should only be allowed to confiscate gambling money when the account was involved in fraud and tried to take advantage of the casino. In this case I don't see any issue and it's not write to take his money away. The casino could have just banned him from their website and at least let him take his money with it. They took immediately the most drastic step without some escalation before. What if people have multiple phones? Like one for work and one private one, you could also use the phone from your wife if you have no battery.  Hopefully your friend gets legal help and can recover some of his money.

from my understanding of what the OP posted, the person he knows got banned and their money confiscated from a casino for using 2 different IP addresses when accessing the account/platform and the reason why the IP address changed was because the person he knows changed SIM card(a different network provider from the one he previously used) promoting his IP address to also change.

sometimes this problem occurs because of a system error and it is possible that if the funds are actually confiscated, maybe the system detects fraud in the account, even though the account is clean, but sometimes the system error that detects it is very annoying.

to the OP should have taken care of the issue immediately to clear things up. If the casino refuses to give a description, it's clearly a scam casino

Frankly speaking I dont really believe with his story unless he provide a solid evidence to support that the story is real. I have never heard casino ban their users just because the players accessing their account with different IPs. IP changes is a very common situation because players do not only use 1 device or 1 internet provider so IP changes is high likely happening. It would be reasonable if the player is getting banned because his IP is connected to other account while the casino do not allow multi accounts, but getting banned just because different IPs is just unbelievable.

It depends on the ToS  of the site, in the first place. But I personally think that using different SIM cards shouldn't be the reason for a ban, let alone for confiscating deposited money. If nothing else was violated, it shouldn't. Your friend should contact Support, but, of course, if it is stated in the ToS that such actions will result in banning and confiscating, there's nothing much he can do, unfortunately.

Maybe the only way around that IP change is to use a paid VPN and choose the person's country so they stay on the same IP and have no issues with changing the SIM card.

But that person should also be aware that changing the SIM card with a different SIM service provider could cause their gambling account to be in trouble unless they can communicate with the casino's customer service. There must be a way around this and we should look for it. But it seems he doesn't need to use the phone to gamble if he has to change SIM cards over and over again to avoid the problem.

There is nothing harsh about this on users, how can you access the two accounts on the same device, that's like the same thing in my opinion. The sim cards are not the same thing, which is understandable because that will be a different mobile numbers but what about the IP address, it will read the same thing, just the last 3 digits will be changed and it will reveal the same location, now tell me how does that make a difference for two accounts as you claimed? As long as you are using the same device and the same network as the data router, the basic information that will appear on the gambling website will be the same even if you use different mobile numbers.

Well if I'm not mistaken, this could be a 50/50. If I remember correctly, there were issues with one user here in the past and the casino says that it's from the same user, because of the IP and even the OS or the machine that the supposedly account.

So it's a back and forth discussion and eventually the casino wilted under the pressure.

But I do agree, that same device on different IP addresses should be investigated more and the casino shouldn't quickly make their decision and ban or worst confiscate their money.

Your comment makes no sense whatsoever. Normal gambling companies are well aware that IP addresses of users can change and unless something extreme happened like a fraudulent card being used or the IP address originating from North Korea, then there is no reason that they would take action against the account. You don't seem to be telling the full story over here and the fact that you go into unnecessary detail about SIM cards makes it likely that something else is going on. If this person really is your friend, they probably left a little fact out, like they were trying to take advantage of the company by multi-account promotion abuse or using the wrong payment details.

It seems to me that this is quite a controversial issue. Using the mobile network you can get an IP address that was previously used in certain activities that are not allowed in the casino.

The casino will not investigate who broke the rules with that IP address - so I quite understand this practice (on this forum, you can get banned immediately after registration, if you use an IP address from which banned activities were noticed).

But on the other hand if you are sure you did not violate the rules of the casino and got banned, that's a different story.   

I wish you also named the website that you are talking about so we could try and dig if they really have the same issues about other gamblers before.
We don't have the facts, it's difficult to judge someone or something without a full proof. We cannot just speculate about what they have done or if there is really some damage that was done.
Just to answer the question, it's not right. But, it depends on circumstances especially if the gambler told the gambling site about the change of number prior to the confiscation or ban.
They are also trying to keep it clean and maybe it is written in their TOS about one IP per gambler only.

Tell your friends to use a trusted platform in the forum. I keep getting messages via email with attachments my account has been accessed by a previous IP address which was not used when logging in to the site. A trusted platform won't make you dizzy every time you log in, it's much easier than the site you're talking about.
Btw, I'm very curious about the gambling platform you mean because I've never experienced anything like this before.

Maybe you forgot that you already created this thread so I'm reminding you, that there are so many questions about the case you mentioned, one of the questions is for you to mention the name of the casino, and I think that shouldn't be a problem because it can be used as a warning for other players who want to play there that they can face such obstacles so they have to be careful, I access the casino with a different IP address but have only ever faced problems because it uses an IP address from a different country

It always boils down to the terms of the gambling site. If you sign up and agree to all the terms, then there's nothing to complain about. However, based on the standard rules that I believe are acceptable, it's not right to confiscate the balance. They may close the account for violating the terms, but the funds should be allowed for withdrawal, which is the last transaction.

Lots of people would miss out this kind thing but honestly reading up a pile of text when it comes to TOS is always been like default or all of them are the same and this is why some people are really

that confident when it comes on knowing up everything or they do know in default without even knowing that there are things which a company could alter out and this is where some users do miss
on reading it up thats why it is really that important that you should really be that mindful or at least have the time on reading up things so that you wouldnt really experiencing
some problems later on.

Just like the rest been saying that its better to stick with reputable sites for you to assure yourself that you are in a legit place.

I just want to ask some things, did he carefully read the Terms and Conditions? Also, what network did he use in accessing the website? is it by mobile data or  using Wi-Fi? because if he use wifi, it will be the same IP, if he use mobile data then yes IP network will be change often I am not on the side of the casino okay just want to clarify some things.If he use mobile data and  frequently changing his sim then the website will encounter some malicious approach, maybe  it is their cloud  security system who banned the account they find it very suspicious and it is flagged by the system that they may be under ddos that's why it is banned and the funds are confiscated. I don't know the whole story just leaving some cents.

Hi, welcome to the forum. It is essential to read and understand the terms and conditions of any gambling platform before using it. Many online gambling platforms have strict policies against using multiple accounts or attempting to deceive the forum in any way. If the venue has a policy against using various SIM cards, it is essential to abide by it. However, It is not fair or ethical for a gambling platform to confiscate a user's account and deposit a balance without clear justification.

In fact, all the rules and regulations of each casino must have been written clearly in the TOS owned by the casino and anyone can read or study them so that in the future they don't violate or violate existing rules.
If there is a gambler who violates the rules they made, then the gambler must also be able to accept all the consequences of what he has done even if he loses the money stored in the casino.
We don't know what problem actually happened until the casino didn't let him get his money back because in every problem there must be clarity and it's impossible for the casino to do something like that if he didn't break the rules which were quite fatal.
Here I'm not trying to defend each other because I'm just trying to address the problems that were complained about in this thread and trying to look at the feedback that has been given by other members.
Hopefully there will be a bright spot in this problem so that it doesn't become a debate and we can all always address all problems in a wise way.

In this case if any account is seized then it must be one of the scam sites. Because some sites only find ways to cheat account holders in various ways. But I was not aware of any casino closing accounts on such issues. We all know that having multiple accounts is definitely a serious crime in a casino. But if the OP takes action against the casino with evidence then this could be a fair solution.

Btw, @OP can you name that gambling platform that confiscates your friend's fund?  It is essential to know the name of the gambling platform so that we can avoid playing on it in the future.  Another question, any update on the case of your friend?  Is he able to contact and have a conversation with the support staff of the said gambling platform?  Can you share their conversation if there is any?  I believe your friend won't just be idle accepting that his fund is confiscated, so I think there must be some conversation between your friend and the gambling platform.

I think gambling companies should just have better filter methods. I remember they prefer to pick the most simple ones because its far easier to explain to users but as OP stated, gambler/user may need to use different SIM cards, or different e-mail addresses even. Some people may even need to use different modems (or they just prefer to). So gambling companies should consider these are real life possibilities and not scam attempts. Also I never understand reasoning behind putting hand over your user's funds. Its the worst move you can ever do.

Op should explain the details of the case because without a clear explanation then anyone would be imagining to give an answer based on his understanding, so does his friend have multiple accounts, does he use a VPN on the browser and does he use a reputable casino. There is a lot to explain here before Op seeks someone else's opinion and if the casino prohibits him because he has multiple SIM cards to access then he can recover the account using the reset password sent to the email, but if the online casino closes the account without an accurate explanation then you have participating in a scam casino, maybe.

It may be a casino that is based on a country where staff is not aware that having 2 SIM cards is popular among those who live in developing countries, for the sake of getting a better signal to access internet. There is a good reason brands like Xiaomi launched many devices with a such capability in Latin America and India.

It sounds indeed harsh some casino would assume some money laundering is going on because a simple IP change.
There are even countries where people have to use dynamic IPs because their service providers won't give other options.

Waiting for OP to give us more information on this case and see how develops.  ???

It feels like we are missing some vital information here. It is best if we know the name of the Casino so we can contribute better. If we know the TOS of the casino, we can verify if that move is valid or not or if OP's friend really crossed some rules in TOS. For now, we all are just speculating.

Anyway, players should not be banned simply because they use two sim cards or they used another ISP to connect to Casinos. Players could be mobile and could use different wifi or use another card to connect to the internet.

This is close to borderline scam in my opinion,

1. if the user uses different SIM, then obviously will be from a different IP address
2. so if regardless it is from the same mobile phone, it shouldn't be tag
3. OS of mobile phones could also be the same as well as millions of other phone users around the world

Not sure if there are gambling platforms though that somewhat want the users to make the same mistake. Only reputable platforms will do everything to really check the veracity of the users before calling their account and flagging it down.

If that's part of the mechanism of their security system that will trigger multi accounting then the system will trigger an alarm of notification that there's a probability of multi-accounting

It's not right they can do KYC or verification, in other countries you are only allowed sims that are be verified to be in your account, the system interprets it as having two accounts if there are two sims in one device.

That's true and that's the worse thing that can happen to you, so make sure that you do all the necessary precautions not to get the alarm to trigger multi-accounting on your part, read the TOS, and be mindful of how you access the casino.

I find it hard to believe, and I believe there is something missing in this story. There may be other factors at play that led to the ban and confiscation of funds, such as suspicious activity on the account or a violation of the casino's terms and conditions. I have never encountered any issues at any casino due to my Internet connection having a dynamic IP address that changes approximately every 24 hours.

However, it's hard to say for sure without more information about the situation and the casino's policies on IP addresses and account access.

What has sim cards got to do with IP address?
Sim cards are just microchips that operates a particular network as network providers and have got nothing to do with IP address. Its hooks you up to a network and that's it.
IP address are unique codes that identifies a computer device or Internet enabled device in an Internet protocol for communication.

Your account might be frozen or banned should you access certain platforms with VPN and I think that's the case here. Your friend justigjt have been accessing the site in question with VPN and the moment location is observed to change by means of IP address, you face the company's T&C. It's just how it is out here as some means to protect the company.

There might be some part of the story that OP didn't tell to us. SIM cards changing won't just result in a ban + funds being confiscated.

Almost lots of sites allows the use of VPN in the first place.

Let's see if we can some additional information on why that sh*t happened to OP's friend.

Yes it's right to call them out. If any casino accuses you of using multiple accounts just because you use a VPN, call them out. If any casino confiscates your deposits for using multiple phone numbers, then it's right to call them out. After all, if you or anyone else has done nothing wrong and these reasons are being used as an excuse to hold your money, then it's far from right.

yeah this is also what i wanna ask here , it is not like this that ask generally without pointing that said site His friend got bad experience because the impression will remain without justification.
it needs clarification first or at least temporary banning while under investigation.

we must remember that abused is what the site preventing here so question is in need to take answers.

If an action violates the TOS of a gambling site, then the user cannot complain because they agreed to those terms when they signed up. However, good gambling sites will provide warning to their users about changes to the TOS. As a gambler, one can voice their concerns or disagreements with the site's decision, but if it's not illegal, then there's no chance of recovering funds. It's important to note that different countries have different laws when it comes to regulating casinos.

Do not mind that I am late to have a reply on this thread, but I want you to know that I have used different network for gambling before and there was no problem at all, but I do not violate the gambling site rules. Sometimes you may think one thing is the cause of the problem, but the problem can be as a result of another thing, it may be because the person is having more than one account or violate another rules. Is the person not having more than one account?

But have you seen a gambling site that include it in their ToS for gamblers not to use more than one sim or network provider? I have never seen that before on gambling sites. I have used many gambling sites before and no problem like such. If such happens to me, I will be doubting the integrity of the gambling site and find out more of the gambling site if real one or fake, likely to be fake.

Here in my country there're times when my IP address just suddenly changed even though I've been using my gadget at the same place, but it's still acceptable coz it's within the country. If ever I'd be subjected to that kind of ban, I would never ever visit that platform again, coz who knows maybe they'll find another fault and accuse my device for illegal usage of IP or worst is that it'll be banned as a VPN user.

I have heard lots of my neighbors boasting about using VPN on different sites, some are even using it to play on different online casinos, but I didn't hear them complain because of banning. So far most of them are complaining due to losing because of their tempers not because of IP related issues.

Just as the others are saying maybe the platform doesn't have that much good reputation if just because of that they'll ban you even if you show much credentials claiming that it is your very own account. I remembered back 2017, there was also an issue similar to this and that platform immediately lose their customers/users and some potential investors.

all gamblers are obliged to report any casino cheating whatsoever if indeed the casino accusations are not true against them, as long as they have sufficiently strong evidence of course they will win and I also do not agree if the user's deposit money is frozen in any case it is the money even though playing is cheating at least delete it the winning funds don't freeze the deposit money either.

but back to casino rules which usually have their own rules such as if you abuse bonuses or cheat, accounts will be banned and deposit funds will be frozen or confiscated.

from the problems told by the OP, we know better or are more thorough before registering or making a deposit, it would be better if we always read the casino rules. like the thread I visited just said it's better if you want to try on a casino site that you've never visited before, please go to the FAQ first before registering and making a deposit so you don't violate casino rules and your funds are frozen.

Calling a gambler platform a scam is not right. Using different sim cards to access same plat form from the same mobile phone sound like it is a scam. The gambling platform is legalised by the government and it has users security. So if the plat form finds out that a particuler person is using different sim cards to accese the same platform from the same phone, i think is good. If they allow different ip address on the same device, it will lead to the scamming. People will use that opportunity to scam other people in the gambling platform. And for the gambling plat for to have banned anybody, they must have warned against it and maybe someyhing of that nature has happened before.

Change of IP address should not be a reason for banning a user, it's simple as that. If they suspect an account is being accessed by someone else from a different location than the usual, they should simply send an email to the original user to inform them that a new IP address has just signed in using his account, and that should be enough.

They should only freeze the account or the funds if the users requests them to via email if the account is compromised, otherwise, they don't really have to ban the user or confiscate their funds just because of an IP change, this definitely is harsh.

A certain user would really win up a case if he/she had proven out that he didnt violate any rules but still the platform did make out some decision on banning or locking up his funds.
Creating some accusations thread or publicly telling on your situation then the community would be the ones whether they would really be believing whether its  a legit one or not.
Casino does have their set of rules but we cant deny the fact that most of their terms and conditions are really just that the same and only differ
a little bit basing up on their own personal set of rules.

It's due to the fact that we don't know if there are other things that OP's friend got violated.

Even a not known gambling site won't just confiscate funds for that kind of reason.

Not unless the site OP is referring to, do have an inappropriate behaviour right from the start and not trustworthy.

maybe it is best to announce which site is this so we can verify its activities and we can warn others from this as mostly this is either scam site or new site that starts to scam people.

and cruelty in gambling more happens as this is about money and we knew how money works in gambling world.

and this, as we have seen many site here that has this activities .

In most online casinos, the rules for creating and using accounts regarding ip addresses are clearly defined, which boil down to the following: you can create only one account from one IP, one computer (read MAC address), for one apartment, one house, one family. But let's say you decide to log in to your account using public wifi, then in this case you are using an address from which someone else could have already entered this casino with a very high probability. As a result, the casino administration will consider multiaccounting, bonus abuser, abuse of bonus programs, violation of the rules of use and terms of play at the casino and others. Which of course does not just give the casino the right to withdraw your winnings, moreover, it is obliged to do so, according to their own T&C.

This is a one sided story. If you were able to read and include the company TOS in the OP, we could be able to determine whether or not it's a scam.
Well, for most gambling websites, they all have their own TOS and once you've violated one, they will either suspend your account and temporary lock your funds, or ban your account along with your funds. That purely depends on the severity of the violation. There are gambling websites who don't allow multiple accounts, so in this case, it's either it's on you because you've violated their TOS, or the gambling website just want to make an issue out of it.
BUT, since the gambling website detected your multiple accounts, most probably they don't allow it.

I've one time played on a casino that doesn't permit one user to handle more than 1 account, it was understandable since their benefits was highly favourable.

I think that kind of casino would also kick anyone with dual SIM out perhaps with the notion that you're going against the rules

The majority of the casinos have that rule on how many accounts a user should have on their platforms. I think if you've got plans of having another account on them, it's best to communicate with the support and ask that personally although it could be visible on their TOS.
And having that confirmation from them alone will give you proof if it's supported or not by that casino. If you're just playing by their rule, obviously, you'll get the answer that it's not allowed. However, there could also some consideration if you tell them that you've got a valid reason for that.

Every casino has every rule and regulation, and terms and conditions written in very clear words in their terms and conditions page which are supposed to be read by the user before getting involved monetarily with the platform. But, if they don't do that, and then get in trouble by going against one of those terms, they don't really have the right to call out the casino for it.

Most casinos are against using VPNs, though there are some that are quite friendly with such things like Stake, it is not really taken as a good and safe activity by the most. And they have it written in their terms and conditions, if they don't, then the user has all the rights to call them out, otherwise, it's their own fault.

Possible, it's only one side of the story so there could be other violation that the OP's friend might have committed that the gambling casinos have to ban them for that intrusion.

So if this is the case, and if his friend didn't commit any then he should file for a scam accusations and see how it goes. It could go on an arbitrage or the casino themselves will explain everything here.

First, that should be allowed because of different IPs from different data on separate sim cards. It must be from location/GPS why the two accounts was shut down. I don't know if OP knows that or if the platform used by him has the same feature. Stake.com has that kind of feature where they can trace the nearest place where you logged in, your IP, and the browser used.
Is there a chance you just used the sim 2 data but used the same browser? Because that can be a red flag.
I mean, there must be a mistake in your end unless the gambling site you are using is a scam.

There should be an investigation and the player should file a complaint, casinos cannot be too harsh on players without reason, because players can hit back by posting accusations here on Bitocintalk and other platforms and this will count as a reference against the casinos.
If the casino accumulated a number of unreasonable bans and restrictions the gambling community will consider this casino as bad to their standard and mark it as a casino that players should avoid playing.

Its not really that justifiable if we do speak about the violation since it is really just that most platforms nowadays would only take out actions if they would be finding out lots of accounts which its been

accessed on the same or similar IP which it would be that understandable that there's an error or fault on users side, but on this one which an account been accessed on different IP's due to different SIM's

then i dont really see that there's wrong on this one.It turns out that it is really just a common thing on where a certain user would really be having those probabilities due on having
some dual sims of their devices but its actually not a violation for a certain platform to throw on.
