Chosen Solution
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!
You may have tried this already, found this info. on a forum. from settings turn cellular (mobile) data off. Turn Airplane mode on, power off phone, wait about a minute, power phone on, turn airplane mode off, turn cellular data on.
