Actually yes, problem is that sim card is expiried and there is no way to reactivate it, I checked all options with operator(s). Thanks anyway, if I find service or way how to do this, I'll post here, so we can close the topic, in meantime, any advice is more than welcome. thank you guys.
Your phone number doesn't belong to your SIM card, you can change your SIM card and even your operator in most countries and keep your phone number, it's called the
Mobile number portability. Usually you have to ask a code to your operator (a
Porting Authorisation Code) and give this code to your new operator to allow it to make the portability. So if your phone number is still working you could try to change your operator in order to get a new SIM card for this phone number.
I have SIM in physical possession, but somehow I can't reactivate it. I need to receive codes to login on accounts.
The point of 2FA is that nobody can access it without having the right device. You'll need to find other ways to change access codes.
That's why SMS 2FA is not the most secure method, you can be
SIM jacked.
