How to untie the mobile phone number?

If you use a vivo phone, it refers to how to change the phone number of the vivo account.

1. You are using a vivo mobile phone, and the mobile phone number/emergency contact/email/secret protection bound to the account is still in use. You can enter the mobile phone settings-click on the top account-security and password-secure mobile phone number-modify the secure mobile phone and reset the mobile phone number according to the prompts. If the system detects that the account is highly secure, you can directly set a new secure mobile phone number. If you are prompted for authentication, you can modify it after authentication.

2. If all the above methods fail, you need to appeal to reset through your account. Please click on the link on the link page and fill in the complaint account with relevant information according to the prompt.
