What should I do if my mobile smhd real name fails?

You can apply for real-name authentication again in the offline business hall. Because real-name authentication is a key factor in whether a mobile phone card can be opened. Therefore, when the real-name authentication is unsuccessful, you can go to the mobile business hall for manual real-name authentication. Generally speaking, there are two reasons for the failure of real-name authentication. One is system failure, just try it a few times. The second is that the real name registration is full. This number can only be used when you want to cancel your account.
