Case like this, the problem could be with the SIM card slot or your phone is still lock up with your previous service provider. If the issue is caused by the latter reason, then you need to contact your provider to have the phone unlocked so you can use it with any other networks. To check if the problem is not with your SIM card slot, try to insert the SIM cards to your other phone (if available). If the SIM cards work and the other phone is getting cellular network connection, try troubleshooting your device before heading to Samsung store for a possible repair. 1. Insert the SIM card back into your Galaxy A20 and make sure that it is properly inserted. Then turn on your phone and see if it is still showing mobile network not available. If so, move on to the next procedure. 2. Soft reset your Galaxy A20. > Press and hold the Power and Volume down key for up to 45 seconds. Wait for the device to restart. Once the phone is on, check if the error message is already gone. Otherwise, try the next solution. 3. Make sure your Galaxy A20 is not on Data Roaming. When your phone is on roaming status yet you are not out of the country, the phone will have issue connecting to the network. If so, then you have to deactivate this feature. Here is how: > Go to Settings. > Tap Connections. > Select Mobile Networks. > Go to Data roaming and disable the feature when needed. After that, restart your phone and check if the mobile network issue has been fixed. 4. Check Airplane Mode and make sure it is off. Another thing that you should be mindful of when using your phone the Airplane Mode. When the Airplane Mode is on, it will suspend the signal transmission. 5. Check the phone’s network mode. GSM carriers usually 4G or LTE network work. To ensure that the phone is set to the correct network mode, do these: > Head to Settings. > Tap Connections. > Tap Mobile networks. > Tap Network mode and select 4G or LTE or auto-connect. If the phone is still having mobile network issues up to this point, try the next option. 6. Start the phone in Safe Mode. Third-party apps can also be the underlying cause. Starting the phone in safe mode will only allow pre-installed apps to run. Here’s how: > Turn the phone off. > Press and hold the Power key past the model name screen appearing on the screen. > Release the Power key when SAMSUNG appears on the screen. > Right 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. If the mobile network is still not available, try the last option. 7. Wipe the cache partition. Corrupted data cached partition on your device can also hinder the phone to connect to the available network in the area. To rule this out, follow these steps: > Turn off your Galaxy A20. > Press and hold the Volume Up and the Home keys, then press and hold the Power key. > When the device logo screen displays, release only the Power key > When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options). > Press the Volume down key several times key to highlight ‘wipe cache partition.’ > Press the Power key to select. > Press the Volume down key to highlight ‘yes’ and press the Power key to select. > ‘Reboot system now’ is highlighted when the wipe cache partition is complete, > Press the Power key to restart the device. If none of the solutions fixes the problem, your last option is to perform a factory reset which will cause data deletion. But you can back-up your files beforehand. Meanwhile, if the phone is not detecting any of the SIM cards but the SIM cards work fine when inserted to another phone, you need to bring your phone to your nearest Samsung store for a possible repair. 0 Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerYou must login or register to add a new answer.
