New iPhone 7 - No Service with activated SIM card
I received a new iPhone 7 yesterday. Picked it up at the AT&T store yesterday and was able to use it on the AT&T Network - I made a few calls, sent texts, etc. Then I went home to restore from backup on my desktop to load up my apps, etc., and it has said "No Service" ever since. I cannot make or receive calls at all, and cannot text, access email, etc. unless there is a wi-fi network available. The SIM card has been activated, and works if you put it in another phone (tried that at the AT&T store today). I've tried resetting the phone completely by restoring as a new phone twice (meaning I didn't restore it from a backup) - that didn't work either. I went to the Apple store and they ran their diagnostics -- all were fine so it's not a hardware issue. My other Apple devices are all functioning using AT&T's network so there is definitely service where I am.
