iPhone 12, iOS 26
Start by checking if you have entered your SIM card PIN. During the update, your phone will restart and you will need to enter your SIM card PIN to log in to the cellular network again.
Go to Settings > Cellular > SIM PIN.
If you have already entered your PIN, try restarting your iPhone. If you are using eSIM, make sure it is active - this is also done in Settings > Cellular. If you are using a physical SIM card, try removing it and reinserting it. If none of this resolves the issue, contact your network provider.
