How to set email SMS reminder in QQ mailbox? I remember doing it before, and then I changed the number. I don't know how to set it now.

Hello, you have probably opened your mobile phone number email before. Since you need to change your mobile phone number now, please log in to the QQ email page first, click Settings at the top left, find account management on the account tab, and click the right side of the mobile phone number email to immediately cancel the original email.

Then, you can click to register your mobile phone number in your email account and follow the instructions of the wizard. You may be asked to send a text message at this time. You can send text messages according to the instructions.
