Galaxy S8 “Mobile network not available” [How to do]

1) Remove the SIM and restart

Some users were able to solve this problem on the Galaxy S8 simply by turning off the phone and removing the SIM card. This troubleshooting step can effectively solve the problem if the error is due to an error related to the SIM card.

Before removing the SIM card from the phone, make sure the device is turned off. Then, after removing the SIM card, wait about 5 minutes before reinserting the SIM. This will force the phone to reconfigure the network settings to re-establish communication with the network.

If the bug has developed in the communication of the phone with the network, this step can help.

2) Perform a soft reset of Galaxy S8

There are cases where a technical problem with the software can cause this problem, which is why it will be necessary to update the phone software. What you will need to do is reboot the phone which should eliminate any temporary data corrupted in the device that could cause the problem.

This step will also restore the phone’s connection to the network which usually solves this type of problem.

  • Press and hold the power button and volume down for up to 45 seconds.
  • Wait for the device to restart.

Check if the problem with the Samsung Galaxy S8 mobile network is not yet available.

3) Make sure Airplane Mode is off

Airplane mode is a phone setting that is usually used when you are on an airplane. When activated, the phone will not receive or transmit any wireless signal so as not to interfere with the aircraft’s electronic equipment.

If you are experiencing an issue with the unavailable Galaxy S8 mobile network, make sure airplane mode is turned off or you can try activating this switch if it is already in the off position.

4) Change the network mode on your Galaxy S8

Make sure your phone is using the correct network mode that matches the one used by your phone operator. For most GSM operators, the phone must be set to 4G or LTE.

  • Open the Settings app.
  • Tap Connections.
  • Tap Mobile networks.
  • Tap Network Mode and select 4G or LTE or automatic connection.

Check if the Galaxy S8 mobile network is not yet available.

5) Start the Galaxy S8 in safe mode

There are cases where an app you downloaded from the Google Play Store causes problems on the phone when it is installed. To check if an app you have downloaded causes the problem, you will need to start the phone in Safe Mode as only pre-installed apps can work in this mode.

  • Turn off the device.
  • Press and hold the power key beyond the model name screen that appears on the screen.
  • When SAMSUNG appears on the screen, release the power button.
  • Immediately after releasing the power button, press and hold the Volume down button.
  • Continue to hold the Volume down key until the device restarts.
  • When the safe mode is displayed in the lower-left corner of the screen, release the Volume down key.

In the event that the problem does not occur in this mode, it is most likely caused by an installed app. Find out what this app is and uninstall it.

6) Perform a factory reset of Galaxy S8

If the error “Mobile network not available” on the Galaxy S8 persists, do not hesitate to delete the device by restoring the factory settings. This is a drastic step that will delete your files, remove apps and restore software defaults, so be sure to back up your data in advance.

  1. Turn off the device.
  2. Press and hold the Volume up key and the Bixby key, then press and hold the power key.

  5. Press the power button to select.
  6. Press the Volume Down key until “Yes – clears all user data” is highlighted.
  7. Press the power button to select and start the main reset.
  8. When the general recovery is complete, “Restart the system now” is highlighted.
