Qq unseals and sends SMS blank.

You must use a bound secure mobile phone to send SMS. Sometimes the server is busy, and you may not be able to receive short messages. Suggest sending it another time.

If prompted, if it is released after 6 hours, it will be released automatically after 6 hours, otherwise it will be released manually.

You can click 2/login _ limit/login _ limit _ index.

Input account information, wait for approval to remove protection mode, or install QQ security center in mobile phone to remove protection, which is the most effective solution at present.

I hope I can help you and hope to adopt it.
