Possible reasons why WeChat binding bank card prompts do not match bank reservation information

Xiaobian always prompts that the information reserved by the bank does not match when using WeChat to bind the bank card. I can't remember the ID card number. I made a mistake. The bank can't pass it. The only thing that may not match is the mobile phone number. But for many years, I only use this one mobile phone number. It is impossible to be wrong. . In order to ensure that, in case, I also logged in to the online bank to check the reservation information, it is indeed this mobile phone number.

After reading various precautions, Xiaobian has already opened the online banking and the mobile phone number is correct. Why is it still suggesting that it does not match the bank reservation information? After a few searches, I finally found the reason. The reason for opening online banking and opening online payment is not the same. You need to go to the bank counter to apply for online payment, and then reserve the mobile phone number. It will take effect 24 hours after the application. Oh, the children who are in the same situation can try it. .
