How does Unicom Wopaika authenticate the real name of SMS?

Unicom SMS real-name registration system registration is to reissue the real-name registration system for old users. You can send the short message "SMDJ" (case-insensitive) to 100 10 and operate according to the system reply. New users can't register in the real-name registration system by SMS. New users can register in the real-name registration system at the card purchase point or their own business hall with their valid certificates.

Or old users can log in to the online business hall/click on the real name registration column to enter the real name registration page, and input customer information according to the page prompts: the name (name), certificate type (category), certificate number and certificate address recorded on the certificate can be registered in the real name registration system.
