Phone number of receiving illegal text message

1. Don't owe the mobile phone card. 2. Have you sent many short messages before? If so, it is possible that the short message function has been shut down by the operator, and such short messages will be completely invalid. You need to call 10086 to find a manual customer service to help you open it before you can continue sending it. 3. If the above 1, 2 is invalid, have you changed your phone settings? You can consult 10086 to tell you the correct SMS center number, and you can change it back. You can put your mobile phone card in someone else's mobile phone and send a text message to confirm whether it is a card or a mobile phone problem. I hope it works for you.
