Updating at t roaming
You may need to contact your carrier for further assistance on SIM card testing and/or replacement. Just press and hold the Power and Home button for a few seconds until the red slider appears. After a few seconds, press and hold the Power button again until the Apple logo appears.
The process won’t erase any data from your device, thus, it’s guaranteed safe. For some reasons, others have found this a temporary solution.

During the first hour or two of the update going live, customers updating over-the-air were finding their devices bricked which requires connecting to a Mac or PC with i Tunes to resolve.
I also include some temporary solutions and user-defined fixes shared via forum posts by other i Phone owners who have dealt with similar issues on their device. If the SIM card is damaged, then it’s time to get a new SIM card. After removing and re-installing the SIM card, reboot your i Phone.While the recommendation for T-Mobile i Phone customers on i OS 9 or earlier is to hold off on updating to avoid the problem, the carrier says i Phone customers already affected by the issue can reboot the i Phone to temporarily restore cellular connectivity.The cellular connectivity issue reported by T-Mobile customers isn’t the first problem we’ve seen so far with i OS 10’s launch.Let me explain: If I check the SIM (About Device SIM cart Status) it shows: Mobile Network type HSUPA Mobile network state: Connecting Service State: In service Roaming: Roaming If I manually select the Network Mode to 2G everything looks good: Mobile Network type EDGE Mobile network state: Connected Service State: In service Roaming: Roaming But even in this case I still have NO MOBILE DATA connectivity.
I just returned from a week in the High Country (Western North Carolina) and my Verizon phone was constantly switching to Extended on Carolina West Wireless as they have a far superior network in NW North Carolina (Boone, Banner Elk, Foscoe, Minneapolis, Newland, ect) From what I understand Carolina West Wireless is a rural LTE partner with Verizon but when on their network I only received 3G service even though they have LTE up and running.
The issue appears to be affecting i Phone 6, i Phone 6 Plus, and i Phone SE customers, according to the carrier, although it’s possible a wider group of i Phones including the i Phone 6s and i Phone 6s Plus could be as well.
