What if the mobile phone can't send text messages in different places? The SMS center is set up.

If the mobile phone card is in a normal state and can't send SMS, you can check whether the SMS center number on the mobile phone is set correctly.

The number of China Mobile SMS Center is +86 13800XYZ500, where XYZ is the part of the area code to which your number belongs, and 0 is added at the end of less than three digits. For example: Nanjing area code 025, XYZ corresponds to 250; Shenzhen area code 0755, XYZ corresponds to 755.

Secondly, check whether the mobile phone card can be dialed out and put into other mobile phones to try to send it normally ~
