3. Remove and Reset the SIM Card

A potential reason behind the “Not Registered on Network” error in Android could be an issue with the SIM card. It might not be inserted properly or could have loosened with regular use.

To address this, start by accessing the SIM card slot. If your phone includes a SIM card ejector tool, use that; otherwise, a paperclip can serve the purpose. Insert the tool into the hole beside the SIM card slot to eject the card and tray.

After a few seconds, reinsert the SIM card and tray back into the SIM slot to ensure a proper connection.

4. Update Your Android Device

Encountering the “Not Registered on Network” error on your Android device might prompt the need to ensure you have the latest updates installed. Updates often contain crucial bug fixes and security enhancements.

If you’re operating on an older version of Android, manually checking for updates is advisable. There might be an essential bug fix available either from the Android system or your device manufacturer that could resolve this error.

The steps to check for updates can vary among different phones. For most users, accessing Settings > System > System updates should suffice, although the menu names could vary slightly. For instance, on a Samsung Galaxy device, you’d navigate to Settings > Software update to check for available updates.

After downloading and installing any available updates, once the process is complete, verify if the error persists.

5. Reset Network Settings on Android

When network settings aren’t aligned correctly, it can trigger the “Not Registered on Network” error. The solution? Resetting your network settings on Android is a straightforward process.

To reset these settings, here are the steps to follow:

  1. Open Settings on your phone and navigate to the System option.
  2. Look for and select Reset options from the menu.
  3. Choose Reset Wi-Fi, mobile & Bluetooth from the Reset options screen.

7. Try a New SIM Card

If you’re still experiencing issues with the “Not Registered on Network” error on your Android device, consider trying a different SIM card. Remove your current SIM card and replace it with a new one.

If you don’t have a spare SIM card, reach out to your carrier, and they can send you a replacement. Alternatively, visit a local retail location if one is accessible. If the new SIM card resolves the problem, it indicates an issue with the old SIM card, and using the non-functional one is unnecessary.

However, if the problem persists with the new SIM card, there’s a likelihood that the SIM slot itself is damaged, and in such a case, seeking professional repair is advisable.


The ‘Not Registered on Network’ error can be a frustrating experience, but with patience and the right troubleshooting steps, you can often resolve it. Start with the simplest solutions like restarting your phone and checking the SIM card, then work your way up to more complex actions like network settings resets. Remember, it’s always a good idea to contact your network provider or the device manufacturer for support if the issue persists.
