There is no call record on the mobile phone. What's the matter if you can't receive or send text messages?

If your mobile phone can't send and receive short messages, we suggest that you:

1. Check whether you can make a phone call, and rule out whether the phone bill is insufficient or the network signal is unstable.

2. If the call is normal, but the SMS cannot be sent, please check whether the SMS blacklist function is set.

3. If you can't receive the short message, please check whether the information center number is entered correctly (hint: the telecom card has no information center number setting).

4. If you can't send and receive SMS, it is recommended to try to replace another SIM card.

5. If it is invalid, please back up the information (contacts, pictures, etc.). ) and restore the phone to the factory settings.

If the problem still exists, I suggest you take the purchase invoice and replacement card and send your mobile phone to the nearest Samsung service center for testing.
