No service with ATT on iOS 9.3.1 or 9.3.5
Hey folks, I'm at the end of my rope and could use some outside help. I have an iPhone 6 which will not maintain service with ATT. Here's what I've tried so far:
Update carrier... stuff - No change
Roll back carrier stuff - No change
Reset network settings - First time, worked for 5 minutes then no service. No change when repeated.
Reset all settings - First time, worked for 5 minutes, then no service. No change when repeated.
Switch SIM card with working phone - SIM works in other phone, other phone's SIM does not work in this phone
Update iOS to 9.3.5 from 9.3.1 - No change
Reattempt above - No change
Restore from backup - No change
Restore as new phone - No change
Banging it - No change
Disassemble phone, ensure all connections are maintained - first time, worked for 5 minutes, then no service. No change when repeated.
Reattempt above
Replace wifi ribbon cable - First time, worked for 10 minutes, then no service. No change when repeated
Reattempt above
So, at this point, I'm not sure what components could be on the fritz or what underlying problem could exist. Is there another antenna chip or cable worth investigating? Thanks!
Is this a good question?

@lpfaff1 Appreciate it. I did try this before without effect. I couldn't recall all the strange sequences I found on random forums, though they're surprisingly popular.

Is this still an issue? If not, how did you solve it?
Out of curiosity, are you connected to WiFi? iOS 9.3.x introduced WiFi calling for AT&T. Can you make a call when connected to it?
