Many times, the problem causing your Android phone to not recognize your SIM card is easily resolved with a bit of troubleshooting.

Restart Your Device

Reinsert the SIM Card

Firstly, carefully remove the SIM card from its tray. Inspect the SIM card for any visible damage such as bending, cracks, or excessive scratches. Also, examine the SIM card tray itself for any signs of damage or debris.

Then, gently clean the gold contacts on both the SIM card and the SIM tray using a dry, soft cloth or compressed air (avoid using liquids). After that, reinsert the SIM card, ensuring it's firmly seated and aligned correctly. Double-check the tray is securely pushed back into the phone.

Toggle Airplane mode

Sometimes, toggling Airplane mode on and off can force a refresh of your phone's network connections and resolve underlying SIM card detection issues. Activate Airplane mode in your phone's settings. Wait for about 30 seconds, and then deactivate Airplane mode. Your phone should automatically attempt to reconnect to the network and register your SIM card.

Reset Network Settings

If toggling Airplane mode doesn't work, then try reset the network settings to restore your Wi-Fi, mobile data, and Bluetooth connections to their factory defaults. This can be helpful when a faulty network configuration is interfering with SIM card recognition.

To reset network settings, please navigate to your phone's Settings > System > Reset options > Reset Wi-Fi, mobile & Bluetooth. Be aware that this will require you to re-enter your Wi-Fi passwords and re-pair any Bluetooth devices. However, it won't delete your photos, music, video and other documents.

Update or Rollback Software Updates

Besides the reasons above, outdated or buggy software can also cause compatibility issues with your SIM card. In order to solve this issue, you can check for any pending software updates for your Android phone by going to Settings > System > System update. Download and install any available updates.

If the problem started after a recent update, consider rolling back to the previous software version if your phone allows it (this option isn't always available). You can consult your phone manufacturer's instructions for how to perform a rollback.

Check for Carrier Service Outages

Before assuming a hardware or software problem, check with your mobile carrier to rule out any network outages in your area that might be affecting SIM card activation. Their website or customer support line can provide information about service disruptions.

Try Another Device

A helpful test is to insert your SIM card into a different Android phone. If the SIM card works in another device, it confirms the problem is with your original phone, not the SIM card itself. However, if the SIM card doesn't work in another device, the SIM card itself is likely faulty and needs replacing.

Visit a Service Center

If none of the above solutions resolve the "SIM card is not detected" error, the problem is likely a more serious hardware issue. This could involve a faulty SIM card reader, damaged contacts within the phone, or even a problem with the phone's motherboard.

In this case, it's crucial to seek professional help. Contact your phone's manufacturer or visit an authorized service center for repair or replacement. They will be able to diagnose the problem accurately and provide the necessary repair or replacement services. Do not attempt to repair the phone yourself unless you have experience with electronics repair.
