Bitcoin is not the same as a grin/beam coin where you can able to send offline sending Bitcoin still needs the internet to be able to broadcast the transaction to the mainnet.
You can make transactions offline but you still need an online device to create raw unsign transaction and sign it to your offline device. So it still needs the internet to send Bitcoin.

It's still not possible to that but who knows in the future if there will be some great developments that will happen. Like IIRC, there's this satellite technology that would be like to cover the entire world with a connection on its own and from there, that could be where it's possible to happen. But right now, we don't see it yet because a transaction needs to be mined and confirmed and for it to be confirmed and mined, it'll require to get to connected to the web/internet.

It all comes down to how can I transfer bitcoin payments to you without internet? You can't. A transaction must be broadcast to the network via the internet in order to be verified and then mined in to a block. That does not mean, however, that each individual needs internet access. You simply need some way of getting a transaction on to the internet. Each person can easily sign transactions on their offline devices, and then save those transactions as a small text file. All you need then is some way of getting those small text files to a person/node/service who will broadcast them for you. If you have a public WiFi spot in your community, then you can travel there and use that. If one person has a mobile device or similar with internet access, they could potentially set up a service broadcasting transactions on behalf of other people. There are services which allow you to send transactions via SMS as pointed out above. You could even transmit a transaction via phone call or radio to someone with an internet connection who could broadcast it on your behalf. Since you are posting on this forum, you must have internet access somehow. Could you set up a method using whatever connection you are on now to broadcast transaction on behalf of your community?

In theory, trust is eliminated by following the chain with the most work, hereby by setting up a full node which listens to the Bitcoin network which verifies every transaction and enforces the protocol rules. If you don't have the chain to verify, you need to trust someone else.
So, if the members in your community don't have Internet access, trust is required. Their best course is likely, as described by o_e_l_e_o, to trust you for doing that.

Thanks for the information, you who are masters in this new technology, what do you think about the radio frequency spectrum (although Satoshi in the white paper says BTC is an electronic payment system) it is only sending a few bytes through waves to be able to sign and verify transactions in that radio that in the end will be connected to the blockain network in some way that right now I don't know.

Then you can cover a wider geographical area and anyone can send a transaction via the mesh network to the central point of internet access in order to be broadcast. Note that you aren't sending data which needs to be "signed and verified" via radio, as you put it. Each user would sign the transaction they want to make locally on their own device, and would then send that signed transaction through the mesh network in order to reach the person who can broadcast it on their behalf.

The only way I know that you can transfer bitcoin without the internet is with a physical device such as an Opendime or this new SatsCard product that is being released. Both are by CoinKite but they both require a certain level of trust. Another way that you can transact with bitcoin but not on-chain is with networked lightning nodes. They can be networked with either a mesh network for greater distances or hardwired for short distances but you would still need internet to be able to open and close channels. There is a group of bitcoiners in Berlin who are using lightning offline with a city mesh network ( https://en.wikipedia.org/wiki/Freifunk) to transact amongst each other without being connected to the internet. The lightning nodes only need to be able to communicate with each other directly to update the state of the channels. When either party wants to close or open a new channel, they would need an internet connection but since you mentioned not everyone in your community has internet access, this could be part of your solution.

Thank you very much I think I can do this it helps me a lot https://news.bitcoin.com/no-internet-no-problem-how-to-send-bitcoin-by-amateur-radio/ Everything I need to transfer successfully Bitcoin, or any cryptocurrency, is to know the public keys of the intended recipient. If I have that, I can use ham radio to send money. No internet needed! However, this technology is new and the process is somewhat complicated (there is not much information about it) but I think I can do it. Thanks super geniuses!

One of the ways to handle this is to have a trustworthy Bitcoin/crypto business that prints many private keys loaded with small amount of Bitcoin on multiple cards and sell them to people. It could be done this way:On the back of the cards, print multiple Bitcoin private keys that contain small amount of bitcoins and seal the keys with tough scratchable materials - > then write for example 6 digit codes on the tough seal and seal with another seal that's less tough . The card buyers will first of all scratch off the top seal to reveal the codes then verify that the card is genuine by sending the codes to the verifying company via sms. Once the codes have been unsealed the card may no longer be transferable. The final owner of the card can go ahead and unseal the second layer to claim the private keys. This should be done securely with a reputable company to keep the private keys safe especially during printing & sealing. I prefer private keys loaded with small amount of bitcoins to lessen the risk of losing a card with private keys that contain huge amounts of bitcoins. Your customers could buy many cards when they want to pay for goods/services that cost a lot of money.

Easiest way would be to use something like bitcoin notes that can later be used to withdraw bitcoin to your wallet, and they can be used similar like we use cash today. Other option is with Opendime usb drives made by Coinkite Coldcard wallet team, or there are alternatives that use format of credit cards like Satodime and you can give this to other people. I also heard there is a way of sending BTC with sms messages, but this is centralized, or with radio waves, but that is to complicated for most people.

You can build an off-chain method to send/receive bitcoin with an SMS service; as mentioned here- https://cointelegraph.com/news/bitcoin-without-internet-sms-service-allows-sending-btc-with-a-textIt's basically a USSD dial-up method where one central party will maintain the accounting while the users can send/receive bitcoin by their mobile number or through a bitcoin address adjusted to every number. Users will only see the figure while the central party will have the access to the fund for the on-chain transaction. Pretty much easy I guess.

You can just pass on a storage device where a signed bitcoin transaction is stored. The receiver can then just "cash in" this transaction at any time when he gets to a location with internet connect. Still it is not a perfect way, since you still need the connection at some point.

For now, let's accept the fact that we cannot send bitcoin to another wallet anywhere in the world without the internet, this is the truth here bro. So, there is nothing we can do but follow that we must always have a data connection, for those of us who want to make activity here in cryptocurrency even here in this forum platform. But as far as I know, it is already known if it is possible to have no net in bitcoin in the future, let's just wait for that if we are still alive.

I have stressed my brain and even searched so well on the internet if this is possible to make and complete a Bitcoin transaction without the internet. I'm afraid, all are pointing to one fact, 'it's not possible.' Bitcoin works with blockchain technology and this will always require the internet to validate/complete every valid transaction. And from what you have explained, it's reasonable, yet it will always cause delays in transactions which BTC doesn't naturally cause.

Hi, mmh this could be a problem unfortunately the bitcoin network needs internet but you could still make transactions offline which would always require a connection afterwards anyway. Rather which country are we talking about? How come there is no possibility to have a connection even of poor quality?

- If you have implemented a bitcoin payment system in the local community where you are located, that means you have a business in your area, right? if yes, what kind of business do you have there now? is it some kind of mini grocery? In short, it seems that only a few people in your area have internet access, so they can pay you in Bitcoin, is that right? Also, what you say that you can send bitcoin without internet access is not possible at this time. And I have never seen such a transaction that was able to transfer bitcoin without a data connection.

I guess with the help of physical bitcoin, transacting bitcoin without internet is possible but counterfeiting would be a big problem. So, we need lots of infrastructure set up are needed basically to prevent those scammers and abusers. But, I guess in near future we may experience transacting with physical bitcoin with proper set up if some corporate decides about.
Still, there could be lots of limitations we may experience with physical bitcoin like we may not get exact denomination to pay or volatility of bitcoin prices might become a concern for the entire concept of paying in physical bitcoins.

Buy a bunch of those Starlink kits that let you connect to their sattelite infrastructure, and put them outside in some designated area, along with some WiFi boosters if you want.
Then half of the job is done. Then you just have to worry about making a cheap hardware wallet. Or possibly figure out how to make a basic bitcoin wallet for Nokia phones (which run Symbian).
