So my iPhone 4S' AT&T SIM card decided not working out of a sudden today and then started working again and I still don't know what the problem was. First I thought there was a problem with the SIM card but I tested with my old iPhone 4 and it worked, so I think it must be the phone... Have you guys encountered this problem? Please report here!
Got a tip for us?
