Why can't the mobile phone send short messages?

The reasons why you can't send text messages should be analyzed as follows:

1, is the SMS center number set correctly on the mobile phone? If it is not correct, it will directly lead to receiving text messages instead of sending them. You have to change it. If it is correct, you can call 10086 for free, and press 0 to serve you manually ~

2. If the number of the short message center is correct, you still can't send short messages. That's a cell phone problem. I suggest you bring your mobile phone and card to the communication service hall 100 for consultation.
