Why does my Samsung mobile phone keep showing that the data connection is disconnected because you left the local network and turned off data roaming?

If the mobile data of the mobile phone you use is automatically turned off, it is recommended that you:

1. Check whether the latest third-party software (battery management, security guards, system management) has been downloaded from the mobile phone. It may be that the software restricts the use of data, so I suggest you try to uninstall it.

2. If it is not solved, it may be related to the system. You can back up mobile phone data (phone book, SMS information, multimedia materials, etc.). ) and restore the phone factory settings.

If the problem still exists, it is recommended that you take the purchase invoice, maintenance card and machine to Samsung Service Center for inspection by engineers.
