1. No SIM or Invalid SIM Error on iPhone 12

Thanks to Wi-Fi, many people forget the existence of SIM cards. What’s the point of dialing from your phone if you are getting facilities to call and message people without extra charges?

You might not notice that your iPhone has lost the SIM connection until it’s actually needed. iPhone 12 might lose its connection to a SIM card due to a glitch in an update, a damaged SIM or port, improper tray placement, or a malfunction in the iOS system.

3. If enabling/disabling Airplane Mode doesn’t fix your problem, turn off the phone and take out your SIM tray.
4. Examine your SIM to confirm if there’s any damage or not.
5. Put the SIM with the SIM tray back in the phone.
6. Restart your iPhone 12. It should show mobile signals now.
