The mobile phone number tied to QQ has been stopped, so you can't receive information. How to change the bundled mobile phone number?

Hello ~ Method 1: Enter the binding page () and log in the QQ number to be unbound; After logging in, you can see the bound mobile phone number (7 digits will be displayed). If you can recall the original bound mobile phone number according to these 7 digits, you can directly change the unbinding. Operation method 2: If the user still can't remember the original binding number, please log in to the customer service center (/) and fill in the complaint about the loss of QQ account. After the customer service center verifies the identity of the number, unbind it. (But the system will change a new password after the number appeal is passed. )
