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

If you’re receiving a “Not Registered on Network” error on your Samsung Galaxy device, it generally means the device cannot connect to your mobile carrier’s network. The reasons for this error can vary, but it’s typically related to either SIM card issues, network settings, software glitches, or occasionally, hardware problems.

Below is a detailed guide to troubleshoot and hopefully resolve the “Not Registered on Network” error:

1. Restart Your Device: The simplest and most common solution. Sometimes, merely rebooting your phone can solve network-related issues.

2. Check SIM Card:

  • Ensure the SIM card is properly inserted.
  • Check for any visible damages.
  • Try your SIM card in another device. If it doesn’t work, your SIM card might be faulty.
  • Conversely, try a different SIM card in your Samsung device to determine if the device itself is the issue.

3. Airplane Mode Trick:

  • Enable Airplane mode from the quick settings dropdown or the settings app.
  • Wait for about a minute.
  • Disable Airplane mode and check if the error persists.

4. Manual Network Selection:

  • Go to Settings > Connections > Mobile networks > Network operators.
  • Search for networks and wait for your phone to display available networks.
  • Select your carrier manually from the list.

5. Check Network Mode:

  • Go to Settings > Connections > Mobile networks > Network mode.
  • Depending on your carrier and location, choose the appropriate network mode (e.g., LTE/WCDMA/GSM or WCDMA/GSM).

6. Reset Network Settings:

  • Go to Settings > General management > Reset > Reset network settings.
  • Confirm and restart your device. (Note: This will erase saved Wi-Fi networks, Bluetooth connections, and other network settings).

7. Update Software:

  • Check for any software updates. Carriers sometimes push updates to enhance network compatibility.
  • Go to Settings > Software update > Download and install.

8. Clear Cache Partition:

  • Turn off your phone.
  • Press and hold the Volume Up button, the Bixby/Power button (or just the power button in some models), and the Home button (if your model has one) simultaneously.
  • Once the Samsung logo appears, release all buttons.
  • Use volume buttons to navigate and select “Wipe cache partition” using the power button.
  • After the process is complete, select “Reboot system now.”

9. Factory Reset: Warning: This will delete all your data.

  • Back up all your data.
  • Go to Settings > General management > Reset > Factory data reset.
  • Follow the on-screen instructions. (Note: Before proceeding, make sure your data is backed up to Samsung Cloud, Google account, or any other backup service you prefer).

10. Check for Hardware Issues:

  • If you’ve tried all the above steps and nothing works, it might be a hardware-related issue.
  • Inspect your phone for any visible damages, especially around the area where the SIM card is inserted.
  • If you recently dropped your phone or it came in contact with water, the network module might be damaged.
  • Consider visiting a Samsung service center or a trusted technician.

11. Contact Your Carrier:

  • It might be an issue from your carrier’s end. Maybe there are outages, or perhaps there’s something wrong with your account.
  • They might have solutions specific to their network or further diagnostics to offer.

Hopefully, one of these solutions will work for you. If not, it might be time to consider professional repairs or even a replacement.
