You can take several actions to try to fix the problem if you receive the message “Invalid SIM.”
Restarting your phone is the first thing you should do when you see the “Invalid SIM Card” error. This frequently fixes minor software bugs that could be the source of the error.
Reinserting your SIM card is the next step if restarting your phone doesn’t help. Please turn off your phone, take out the SIM card, inspect it for any obvious damage, and then put it back in, ensuring it’s position correctly and firmly.
Try reinserting the SIM card into a different phone if you still get the “Invalid SIM” error after doing so. If the SIM card functions on the other phone, your phone is probably the issue. If the SIM card doesn’t function in the other phone, the SIM card itself is probably the issue.
Resetting your network settings is a different action (iOS guide/Android guide). Your phone’s network settings will completely erase and reset. Remember that doing this will also delete any saved Bluetooth and Wi-Fi pairings.
It’s time to contact your carrier if none of the above measures work. They can determine if there are any problems with your account or the local network. They can give you a new SIM card if the SIM card itself is the issue.
