Why failed to send the verification code when logging in the salted fish SMS verification code?

It may be a network problem, it may be a wrong number input, it may be a problem with the operator, or it may be that the mobile phone was intercepted when it was turned on.

The mobile phone verification code has some services that the mobile phone can customize through the website. That is, enter the mobile phone number on the service opening page, and the system will send verification information to your mobile phone. The verification code received by the mobile phone needs to be input into the page again, and the related services can be opened on the mobile phone only after the system is verified.
