Title: Is this a backdoor or a known thing, android and sim cards Post by: jackg on March 22, 2019, 11:35:45 PM I turned on my phone for it to tell me it was going to restart, and it restarted saying something about a local sim and it set the home page on chrome to be my network provider (I was connected to uni WiFi and its not a virus as it had an authenticated certificate signed as expected).
My question is, is it normal for the sim card to have some control over a phone (I thought it was the other way round). The phone was bought as a sim free thing and then I got the card later...

Like what's the message about in details?
I never experienced things like that even though I change my SIM regularly. Title: Re: Is this a backdoor or a known thing, android and sim cards Post by: lukew on March 23, 2019, 03:46:17 PM Sounds normal to me, SIM cards contain config data for connecting to the network, setting up APN's, passwords etc. Makes sense for the povider to send you to their website to create an account etc.

The sim is with a sub company of vodafone and the sim was in the phone for a few months before it did this.

I don't know much about Android, but if I understand correctly, many carrier phones include an app called Mobile Services Manager which can be used to install stuff surreptitiously. Here's one thread on the subject: https://forum.xda-developers.com/galaxy-s9-plus/how-to/psa-disable-mobile-services-manager-apps-t3764366.My question is, is it normal for the sim card to have some control over a phone (I thought it was the other way round). The phone was bought as a sim free thing and then I got the card later... I'd be interested in hearing more about this.

May have been a system update, phones come with all sorts of crap pre-installed now as they get paid for it.

You should go ahead and ask their customer service representatives why is that they have installed facebook on your phone. That is your concern right and you have to stand for it!

There's a 3 hour hold with Vodafone. I could try calling at 4am tomorrow although there will probably be the same wait regardless.

I suggest to take his advice as well as please reset the sim settings you can find under "Network and internet" this is stop all the sim access apart from calling and messages service. |
