iPhone detected cellular issue

My phone was on airplane mode for almost a month. When I finally turned airplane mode off, a notification popped up saying “CELLULAR ISSUE DETECTED.” I tapped on it. I tried restarting the phone and resetting the network settings multiple times, but I’m still facing the same issue. My phone stays on SOS with no service.

I called my carrier, and they said they don’t see any issue on their end. I also called Apple Support, and they told me the same thing. Also if I try to update my software phone gets struck at verifying update.

Please help me if you can.

Model: iPhone 14 Pro Max

Carrier: AT&T (Locked)

iPhone 14 Pro Max, iOS 26

Did you also try to reset the iPhone to factory settings, which will install a new iOS version? In case there is corrupted data on the iPhone causing this, set it up as a new device without using the latest backup.

If your SIM is detected again, restore from the backup, to get your data and settings back.
