My mobile phone is turned on, but it is turned off when someone calls me. I only send text messages, but I can call others. Why?

If the phone can't receive the other party's call, but you can make a call, I suggest you:

1. Take out the SIM card and insert it again.

2. Try to change the position.

3. Check whether the blacklist (call rejection) function is set on the mobile phone. If so, please cancel the post-test.

4. Check whether the call forwarding/call barring function is set on the machine.

5. If there is software for installing security guards in the mobile phone, it is recommended to uninstall and delete it.

6. If it is invalid, back up the data (contacts, text messages, pictures, etc. ) in the phone, and then restore the factory settings.

If the problem still exists, please take the purchase invoice, maintenance card and machine to the Samsung service center, and the professional after-sales engineer will help you test it.
