I received a short message asking my mobile phone card to fill in the information. Why do you want to add user information?

* * In order to severely crack down on criminals using non-real-name calling cards to carry out illegal and criminal activities, safeguard the legitimate rights and interests of the people, and ensure national security and social stability, our department requires telephone users to register their real identity information. Users who have not registered their real names at present will not be able to handle business. Please go to the nearest China Telecom's own business hall for registration as soon as possible.
