The mobile phone number of this card is empty. What should I do if I can't send the SMS verification code?

In this case, you can only reapply for a mobile phone number, and then unbind the mobile phone number that needs unbinding, such as Alipay WeChat, and click Change Mobile Phone Number to enter verification. Unbind. Forget the phone number that needs to be untied. If you can't unbind through the "original mobile phone number" entrance, contact customer service to solve it. 2. The account registered with the mobile phone number needs to be replaced with the login name.
