If your Samsung galaxy S10 device shows the "mobile network not available" error, then you will have to fix. Check the whole post in order to learn what you can do to fix your device's issues.

"Mobile Network not Available" error might be due to bad software, 3rd party apps installed from unknown sources, bad or unseated SIM card, Roaming enabled, bad signal due to being in a remote location, and others.

The first thing that you need to verify is the signal icon, and if there are no bars, then you should reboot the phone first. After you reboot the device check again, and if there are still no bars, then you should try and reseat the SIM card.

Open the SIM card tray and remove the SIM, then place it back in and reboot the phone. If the SIM card now works and you're getting connected to the mobile network, then you are done. However, keep checking the device from time to time and see if the problem reappears. In case the Mobile Network issues you are having keep coming back then it migh be due to a bad SIM card, and you should contact your network carrier and tell them about it being faulty.

Another thing you can try is to change the network mode your Galaxy S10 is using. Change the mobile network from 3G to 4G/ LTE and see if the problems keep coming back. In order to change the network mode you need to go to Settings> Connections> Mobile Networks, and change the Network mode to a different one.

Also, you can try to enable and disable Airplane Mode. If this fixes the problems you are having, then you should tell us in comments, as it might be a common bug and multiple Galaxy S10 users might be affected.

Boot Galaxy S10 in Safe and Check for Bad Applications:

If you have recently installed any new apps that you suspect it might interfere with your Galaxy S10 mobile network, then you should remove these using Safe Mode.

If the apps you have installed previously cannot be removed normally, then you can remove them using the Safe Mode. Check the following steps in order to learn how to boot your Galaxy S10 in Safe Mode.

Note that the Safe Mode is going to boot only the stock and original settings of your Galaxy S10, so in case the device's mobile network does work in Safe Mode, then the problem surely lies with a 3rd party app. Here's how to boot the device in Safe Mode:

  • press and hold Power button.
  • release Power and now tap and hold the "power off" icon until it changes to Safe Mode.
  • tap once on Safe Mode and confirm the boot.

When the Galaxy S10 is booted in Safe Mode you can start looking for apps you suspect are changing the way your Galaxy S10 manages the mobile network connection.

Before continuing with the rest of the tutorial you should first contact your network carrier and tell them about the problems you are experiencing, as you wouldn't want to delete all your Galaxy S10 data and later find out that there were problems with the whole mobile network in your area. Check with your network operator and if there are no issues on their part, then you should check the extra info below.

Factory Reset Samsung Galaxy S10:

Note that this method should be used only as a last resort, so you should first backup all your important files. The Factory Reset process will wipe clean the system partition of your device, and you will lose all the installed apps and their data.

Note that we cannot be held responsible in case your Galaxy S10 gets bricked, nor in case you lose any important data files.

Before factory resetting the device you should make sure that the mobile network problems aren't due to a faulty SIM card. Go to your local carrier shop and ask them to change the SIM card, as that might fix your device. If that doesn't the phone, then a factory reset is mandatory:

  • power off the phone.
  • press and hold Volume UP + Bixby + Power buttons at the same time.
  • release the buttons when the Android logo over a blue background loads.
  • wait some 30 seconds more for the Recovery Mode options to load.
  • select 'wipe data/ factory reset' process and confirm.
  • reboot your Galaxy S10 in normal mode when you are done.

These were all the steps that you had to take in order to attempt to fix your Galaxy S10 mobile network problems. If you need more help completing the tutorial, or fix your device, then feel free to let us know in the comments field below.
