- 2
Turn on Airplane Mode (swipe down from top-right, tap the airplane icon), wait 30 seconds, then turn it off.

Go to Settings > General > About. If a carrier update is available, install it.

Make sure your account is active by calling your carrier from a different phone.

Try removing and reinserting your SIM card.
