Hello, we understand how frustrating it is when your mobile does not reading the sim card. Try below steps:

1. Restart your phone and see if that fixes your problem as it often resolves many minor glitches.
2. Turn off your phone by pressing the Power button and take out the SIM card from the SIM card tray. Check for any visible signs of damage like scratches or stains. Clean the SIM card and tray with a clean, dry cloth. Reinsert the SIM card, making sure it is properly installed in the tray.
3. Reset network settings
4. Insert the SIM card into another phone and see if it gets detected. If the SIM card is also not detected by another phone, then the SIM card is already damaged. We recommended contacting your service provider for assistance and replacing your SIM card with a new one.

If the above steps did not resolve the issue, please visit your nearest Samsung Authorized Service Center, so we can assist you further with your concern.
