What is it that Xizhengtong publishes personal information, showing that his mobile phone number has been bound to someone else's mobile phone number?

Your mobile phone number is bound to someone else's card, it must be that your mobile phone number has been used by someone else before, and you don't have a real-name registration system.

The number tied to someone else's card has never been untied. Now all the phone numbers are bought by the real-name registration system, so they will not exist and are still bound to other people's cards. If you can't handle it yourself, go to the bank to untie it and solve this problem. You can also call customer service yourself. You can also enter the mobile APP first, click on the avatar in the upper left corner, then set it, push up the screen until there is an exit login below, click, and then log in with a different mobile phone number.
