QQ registration requires verification code, but SMS did not receive verification code.

You can't receive SMS or verification code due to the following reasons:

1, you can check whether the mailbox is full first. If it is full, please delete some information.

2. I still can't get it after deleting it. You can change your phone or card to see if it is a hardware factor. If it is a mobile phone problem, please contact the mobile phone for specific after-sales consultation.

3. After eliminating the above reasons, you can try to test whether it can be received in other places to see if it is the reason for the weak local signal.

If the above problems do not exist, please contact the local manual customer service of the mobile phone card operator to handle this problem.
