My Samsung note2 mobile phone can't send and receive short messages.

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

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

2. if the call is normal, but you can't send SMS, 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 short messages, it is recommended to try to change another SIM card.

5. if it doesn't work, please back up the data (contacts, pictures, etc.) in the phone and restore the phone to the factory settings.

if the problem still exists, it is recommended that you take the purchase invoice and repair the card, and send the mobile phone to the nearest Samsung service center for testing.
