What should I do if I change my Samsung mobile phone and lose my SMS call?

According to your description, you can try the following methods:

1. Check whether the phone is in silent mode.

2. Press the button on the standby screen to adjust the volume of the ringtone (this operation can also exit the vibration only mode).

3. Play the song to test whether there is sound, and if there is sound. It means that the speaker is not damaged.

4. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ), restore the factory settings (Settings-Reset-Restore Factory Settings), and eliminate the causes of system errors.

If the fault still exists, I suggest you take the three-guarantee certificate of your mobile phone and send it to the nearest Samsung service center for inspection and maintenance. For more information about the service center, please visit:
