I9300 can't send and receive text messages, but can make phone calls. It is useless to restore the factory settings, and the mobile data is also on.

According to your description, I suggest you:

1. Check whether the mobile phone has downloaded the latest third-party software with SMS interception function similar to 360, which may be software.

Incompatibility with mobile phone leads to this phenomenon, so I suggest you try to uninstall it (Settings-Application Manager-Select Down).

Load-unload)

2. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore the factory settings (Settings-Reset-Restore

Factory settings), if the problem still exists, I suggest you take the three-guarantee certificate of your mobile phone and send it to the nearest Samsung.
