How can I receive the verification code of foreign social software?

This method is effective in personal testing, but there is no guarantee that everyone will try it, because I can't do anything that others can do online (what to add to the white list and what to add to the contacts).

1, hang the ladder (I've been hanging it)

2. Register another Facebook with the same qq email address.

3. When the qq mailbox can receive Facebook mail, try again whether the verification code of ig can be received.

4. (If you still haven't received the login verification code at this time) Try the verification code with the wrong password.

Note: Don't use qq email here, use your user name (if you forget your user name, please ask a friend who can log in to help you look at the email sent by ig before, which usually contains your own user name).

If the above still doesn't work, you can try to log in to the English version of qq mailbox and see if you can receive the SMS.

All my operations are done with Google browser and tizi.
