Use a different SIM card: Try using a different SIM card from another network provider or a friend’s phone to see if the issue persists. This can help determine if the problem lies with your specific SIM card or the phone itself.
Check for physical damage: Carefully inspect your phone for any visible damage to the SIM tray or the overall device. If you suspect physical damage, take your phone to a qualified repair technician.

Important note: Always back up your data before performing any advanced troubleshooting steps like factory reset.
