Why didn't I send a text message when I changed my QQ phone to accept the verification code?

Generally, there are the following possibilities for mobile phone receiving verification delay:

1, the problem of SMS sending platform

2. Cell phone signal problem

3, the phone itself.

Usually wait a few minutes in this case.

If you don't receive 10 minutes later, try again.

If it doesn't work, turn off the phone and turn it on again.

If you have any questions, please consult the mobile operator and let them tell you what the problem is.
