How To Fix The Samsung Galaxy A40 Mobile Network Not Available Issue

Make sure that your phone is running on the latest software version before doing any of the recommended troubleshooting steps listed below. If an update is available then I suggest that you download and install it first. It is important that you should check for carrier related software updates as this will usually address carrier related connectivity bugs.

Verify that your area has a good network signal

Sometimes you will find yourself in an area that does not have any network signal at all . To verify if this is a coverage related issue you can check if other devices under the same network are also having the same problem.

However, if you are in an area that has excellent network coverage but your phone is not getting any signal at all then there’s a possibility that the problem is caused by a network outage. You should contact carrier to verify if there is an outage and if there is none then you should proceed with the additional troubleshooting steps listed below.

Perform a soft reset

There are instances when a software glitch can cause this problem which is why you will need to refresh your phone software. What you will want to do is to restart the phone which should eliminate any corrupt temporary data in the device which could be causing the problem. This step will also reset the phone connection to the network which usually fixes this type of problem.

  • Press and hold the Power and Volume down key for up to 45 seconds.
  • Wait as the device restarts.

Check if the Samsung Galaxy A40 mobile network not available issue still occurs.

Check your SIM card

There are instances when the problem is caused by an issue with the SIM card. If this is what’s causing the problem you should turn off the phone then remove the SIM card . Wait for a few minutes before reinserting the SIM card back then turn on the phone. Check if the issue still occurs.

You should also consider using a different SIM card in your phone to eliminate the possibility of the problem being caused by a defective SIM card.

Verify the roaming status of the phone

Generally, you will want to make sure that the roaming status of the phone is off if you are in your home country. This applies to travelers who have returned from a different country and still have the roaming status of the device activated. You can access the roaming settings of your phone from Settings > Connections > Mobile networks > Data roaming.

Make sure Airplane Mode is off

The airplane mode is a setting of your phone that is usually used when you are in an airplane. When this is activated your phone will not receive or transmit any wireless signals so that it will not interfere with the aircraft electronic equipment. If you are getting the Samsung Galaxy A40 mobile network not available issue then you should make sure that airplane mode is off or you can try toggling this switch if it is already in the off position.

Change your phone network mode

Make sure that your phone is using the correct network mode that matches the one your carrier is using. For most GSM carriers you will need your phone to be set to 4G or LTE.

  • Open Settings app.
  • Tap Connections.
  • Tap Mobile networks.
  • Tap Network mode and select 4G or LTE or auto-connect.

Start the phone in Safe Mode

There are cases when an app you downloaded from the Google Play Store will cause issues on the phone when it is installed. To check if an app you downloaded is causing the problem you will have to start the phone in Safe Mode as only the pre-installed apps are allowed to run in this mode.

  • Turn the device off.
  • Press and hold the Power key past the model name screen appearing on the screen.
  • When SAMSUNG appears on the screen, release the Power key.
  • Immediately after releasing the Power key, press and hold the Volume down key.
  • Continue to hold the Volume down key until the device finishes restarting.
  • When Safe mode appears in the bottom left corner of the screen, release the Volume down key.

In case the issue does not occur in this mode then it is most likely caused by an app you installed. Find out what app this is and uninstall it.

Wipe the cache partition of the phone

There are cases when the cached data stored in the dedicated partition of the phone can become corrupted. When this happens this will usually cause certain issues to occur on the phone. To eliminate the possibility that this is what’s causing the problem you will have to wipe the cache partition of the phone from the recovery mode.

  • Turn off the phone.
  • Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  • When the device logo screen displays, release only the Power key
