Why can't mobile phones send text messages?

A, first of all, please confirm whether the mobile phone is in arrears, whether the signal is normal, whether other functions can be used normally and whether the surrounding users have the same situation.

B, check whether the number of the SMS center on the mobile phone is correct: +86 13800XYZ500(XYZ is the area code of this number, and the mantissa with less than 3 digits is 0 and 3 digits are added. Example: Chengdu users should be set to:+8613800280500);

C. If the center number is correct, restart the mobile phone for several times to see if it can return to normal;

D, if it still can't return to normal,

Please take out the card and exchange it for a mobile phone that can be used normally. Please judge whether it is a mobile phone problem or a SIM card failure.

F. In case of mobile phone problems, please contact the mobile phone repairer as soon as possible; If there is something wrong with the SIM card, you can call 10086 to tell us your situation, and we will solve it for you as soon as possible!
