Latest iOS update breaks iPhone users cellular connectivity
Several responses from iPhone users confirmed the issue including this post from “Fuse 1369” which said, “perfectly working 7S – updated to 14.7.1, now it’s a paperweight went to the apple store, your phone is dead, but we can sell you a new one for $700 maybe it’s time for an android.”
Apple’s support document suggests things that users can try to get their cellular connectivity back
Apple also suggests that iPhone users unable to connect to their carrier after the iOS 14.7.1 update reset their network settings. To do this, go to Settings > General > Reset > Reset Network Settings. Doing this will also reset previously used Wi-Fi networks and passwords, cellular settings, and VPN and APN settings.
