What should I do if my mobile phone can't receive the SMS verification code sent by qq Security Center?

It may be the delay in sending the short message caused by the network delay of the operator. You can wait patiently for a while, and the short message may be received later.

I suggest you bind your mobile phone token, which is not only more convenient and safer, but also completely free.

1) Enter the mobile phone token page, and click here to enter.

2) Download and install the mobile phone token according to your mobile phone model.

3) Bind the mobile phone token with the number.
