How to solve the problem that Xiaomi 5s can't send text messages?

Xiaomi 5 can't send SMS because there is no central number. You need to check the advanced settings of SMS to see if the lack of center number caused the failure of sending SMS. The specific operation method is as follows:

1. First, you need to enter a short message.

2. Then press and hold the menu key to enter the SMS settings.

3. Select Advanced Settings to enter, and then check whether the center number is lost, which makes it impossible to send SMS.

4. If the center number is missing, please consult the operator's center number and fill it in.

5. If it is not caused by the central number, you can try to restore the factory settings or consult the operator.
