Samsung Galaxy Note 20 Ultra Mobile Network Problem

[Millz1]

My galaxy note 20 Ultra has lost moble network. I have tried to insert a different simcard but to no avail. I have also tried to factory reset it but still no mobile network. 

As you can see,flight mode is auto enabled and it wont turn off. How can I fix this problem?

Try Disabling Airplane Mode via Safe Mode


Turn off your phone. Press and hold the Power button until the Samsung logo appears, then release it.Immediately press and hold the Volume Down button until the home screen appears."Safe Mode" will display in the bottom-left corner. Check if you can disable Airplane Mode in Settings > Connections.

Even from safe mode ,flight mode could not be disabled

Thank you. Let me try that. I'll update you wether it works or not

Or try updating your phone to it's latest software update, or dial *#06# and check your IMEI if it's shows null or unknown, your phone's network firmware might be corrupted

Unfortunately, note 20 series were discontinued meaning no official updates or support from samsung. Unless I try to root it and update manually

Or try resetting network settings
