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In some cases, Not registered on network error may show due to outdated software.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.

  5. Tap Select manually.

  8. Tap your own network again to register to it.
  9. Check for the issue.

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.

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.
