Encountering a ‘Not registered on network’ error on your Samsung Galaxy? Here’s what it signifies and how to resolve it.

How to Fix a ‘Not Registered on Network’ Error on Samsung Galaxy

Follow these steps in sequence until your phone is operating correctly:

1. Restart your Android phone. Rebooting your device clears temporary conflicts that may prevent network connection.

2. Turn off Wi-Fi. Disable Wi-Fi on your phone, wait 30 seconds, then turn it back on. This resets your connection and may resolve temporary technical issues.

3. Update the Android operating system. Updates often include fixes for specific issues like this error.

   If your phone is rooted, you must unroot it before installing updates.

4. Reinsert the SIM card. Remove your SIM card, check for damage, and place it back, ensuring the metal pins are properly aligned.

5. Manually choose your network. Ensure the correct carrier is selected in your settings.

   Navigate to Settings > Connections > Mobile networks > Network operators > Search now, and then select your carrier’s network.

6. Change the network mode.  If you’re in a low-reception area that lacks 5G support, switch to 4G or 3G, if possible.

7. Contact your mobile carrier. Visit a store or use another phone to call your provider for assistance. There might be a network outage in your area, so waiting may be necessary. If there’s a SIM card issue, your carrier can assist with a replacement.

8. Update APN settings. If you’ve recently switched service providers, updating the Access Point Name (APN) settings might be necessary. As this is an advanced fix, carefully note the default APN settings to revert back if needed.

9. Reset the network settings. Creating a new connection to your carrier’s network can solve issues a reboot can’t fix. Note that resetting network settings will delete all Wi-Fi passwords and Bluetooth connections, so reserve this step as a last resort.

10. Use a different SIM card. If you have a spare activated SIM card, insert it to see if your phone can connect to the network. If it connects, the issue is likely with your original SIM card.

    Before purchasing a new one, check Samsung’s support website for compatible SIMs with your Samsung Galaxy.
