Why you’re getting a SIM card error

If your phone is showing a SIM card error, something might be stopping it from reading the SIM properly. Try these steps to get it back up and running.

1. Take the SIM card out, then re-insert it.

2. Turn your phone off and on again.

3. Turn Aeroplane mode (also called Flight Mode) on and off again.
