[iMore Question]

I updated my iPAD 4 A1459 to IOS 10 and now I get NO SERVICE.
I checked with ATT, no upgrades needed there, but they did replace my SIM card... still NO SERVICE. While at ATT store, immediately after replacing my SIM card, my iPAD picked up ATT signal with "4 bars". When I got home and woke it up, NO SERVICE.

No service usually means you're out of the service area or cellular is turned off. Have you checked your settings?
