My wife updated her phone to 10.0.2 today and she has not been able to call out or receive a call since. We have powered off several times, removed the SIM card a couple of times, we have reset the networks and still nothing and not only that, sometimes when we try to make a call and the call has failed an AT&T pops up where the Verizon is on the top of the screen. My phone is not having any issues and we are on the same plan. Any advice?
