Real fix for “Not registered on network” on Galaxy S10

Not registered on network error is one of the common network errors that a lot Android users encounter. If you got this one in your Galaxy S10, learn how to troubleshoot below.

Not registered on network fix #1: Check for signal and restart

Not registered on network may pop up if there’s intermittent or no signal at all. If you are in an area with poor coverage, try relocating to one with better signal. Or, try moving to an open area and see if that will improve the situation.

Once you’ve already relocated to an open or better area, make sure to restart the device to force it to re-register to your network. To do that, simply press and hold the Power and Volume Down buttons for about 10 seconds. Once the phone has restarted, release the buttons. This is usually effective in clearing bugs that developed when a system is left running for some time. We suggest that you restart your S10 using this method at least once a week to lessen the chances of bugs.

For some Galaxy S10, there may be a slightly different way to arrive at the same method. Here’s how:

  1. Press and hold the Power + Volume Down buttons for approximately 10 seconds or until the device power cycles. Allow several seconds for the Maintenance Boot Mode screen to appear.
  2. From the Maintenance Boot Mode screen, select Normal Boot. You can use the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Wait for up to 90 seconds for the reset to complete.

Not registered on network fix #2: Confirm software is up-to-date

In some cases, Not registered on network error may show due to outdated software. This usually happens if you have a carrier-branded Galaxy device. By carrier-branded phone we mean devices that were provided carriers and not the global versions. So, for instance, if you’re a Verizon customer and you got your S10 from Verizon, your S10 is Verizon-branded version. In this case, make sure that the software running on the device is updated. Try checking under Settings > Software update to see if there’s any update available.

Not registered on network fix #3: Verify if SIM is working

Another important troubleshooting step to do in this case is to ensure that the SIM card is working. There are two ways to do this. The first one is by examining the SIM to check if there’s visible sign of physical damage. If you’ve already inserted the SIM to your device, make sure to carefully take it out from the tray. To avoid corrupting data, the phone must be off before you remove and re-insert the card.

The other way to check if there’s a SIM card issue is by inserting it to another compatible phone. By compatible, we mean one that should work with your current network and can read the SIM. If there’s no Not registered on network error on the second phone, this means that there may be a problem with your S10. Continue with the troubleshooting below.

Not registered on network fix #4: Manually switch to different network

Another trick to improving signal quality in any device is to force it to re-register to the network. Here’s how it’s done:

  1. Open Settings app.
  2. Tap Connections.
  3. Tap Mobile networks.
  4. Tap Network operators.
  5. Tap Select manually.
  6. Wait for the device to scan.
  7. Select a network (not your own).
  8. Tap your own network again to register to it.
  9. Check for the issue.

There can be all sorts of problems when a system cache gets corrupted. Make sure that you clear the cache partition on your S10 to keep the system cache in top shape. This will force the phone to delete the current cache and replace it with a new one over time.

To wipe the cache partition on your Galaxy S10:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe cache partition’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘yes’ is highlighted and press the Power button.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.

Not registered on network fix #6: Reset network settings

To ensure that your device has all the right network settings, you can reset them once. Her’es how:

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap General Management.
  3. Tap Reset.
  4. Tap Reset network settings.
  5. Tap Reset settings.
  6. If you have set up a PIN, enter it.
  7. Tap Reset settings. Once complete a confirmation window will appear.

Not registered on network fix #7: Check for rogue apps

In case there’s a third party app causing calls to keep dropping, the next good thing to do is to restart to safe mode. By third party app we mean apps that you added after the initial setup. Even apps from Google and Samsung are considered third party if they were downloaded right after you unboxed the phone.

To restart to safe mode:

  1. Press and hold the Power button until the Power off window appears then release.
  2. Touch and hold Power off until the Safe mode prompt appears then release.
  3. To confirm, tap Safe mode.
  4. The process may take up to 30 seconds to complete.
  5. Upon reboot, “Safe mode” appears in the lower-left of the home screen.

Remember that third-party applications are disabled in this mode so what you can use are pre-installed apps. If Not registered on network issue won’t appear on safe mode, that means that the problem is due to a bad app. Uninstall the app you recently installed and see if that will fix it. If the problem remains, use the process of elimination to identify the rogue app. Here’s how:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your S10 is still problematic, repeat steps 1-4.

If you recently purchased a carrier-branded S10 online or from someone else, there’s a chance that it may not be able to support the services being offered by your network. Even if you have a GSM device, it does not mean that it can work with any GSM network. Carrier-branded devices are built to work with a specific set of frequency bands or radio frequencies. If your S10 is from another country, there’s a chance that it may not be compatible with your carrier’s frequencies. Do more research and see if this is the case.
