What should I do if QQ is not bound and I can't send text messages?

SMS will be delayed occasionally, so it is recommended to wait for a while. The steps to unbind the mobile phone are as follows:

1. First log in to QQ, click the penguin icon at the bottom of QQ to pop up the "Main Menu", select "Security Center" in the main menu, and click "Security Center Home Page" here.

2. Pop up the home page of the Security Center. On the right side of the page, you can see the secret phone. Click "Replace" at the back.

3. At this time, he asked to fill in the complete mobile phone number. If he didn't fill in the mobile phone number, click "Verify Secret Protection" below.

4. In security verification, you can also choose to use a security card for verification, fill in the correct security questions, and click "Verify".

5. After successful verification, you can fill in a new mobile phone number for binding. Enter your mobile phone number first, and then click the "Get verification for free" button below. After a few seconds, the mobile phone will receive a short message, enter the verification code on the short message and press "OK".

Note: If you want to unbind, you need to complain manually, and just write down the reason for the loss of your mobile phone card.
