What should I do if I change my qq space mobile phone number?

If you change your mobile phone number, you can't log in to qq space with your mobile phone number. You can choose to log in by QQ number, email address and password, not necessarily only by mobile phone number.

If you want to change the phone number bound to QQ space, you can do this:

1. On the QQ login page, click "Retrieve Password" below.

2. Enter the QQ number or QQ-bound email address, and then click Next.

3. Select Data Assistant Authentication.

4. Complete the information. Enter the mobile phone number you are using now, and then click "Submit". Then bind your new mobile phone number, and then you can log in with your new mobile phone number.
