An activation email is sent to the email you provide right away. It may take some time for your mail server to receive. Don’t forget to check junk mail box.
If the activation sent page is still open, check to see if you’ve made a typo in the email address. You can also click to re-send the activation email.
Also please make sure that you have not opened a QQ account with the same email before. Every email account can only register for one QQ number.
If you still don’t receive activation email, you will have to register again with a different email, preferably with a different email provider.
