After iOS 10.0.2 update for iPhone 5s phone will not accept or receive calls. Tried power off several times. Tried removing sim card. Tried resetting networks. Gets voicemail notification but does not ring. When call out, says call failed no service. Even has shown AT&T for a second or 2 on the top of the screen where verizon is normally. Able to use 2 other phones in same location on same plan with no issues.
