Send a short message verification code to an empty phone number, will you receive it? It's a cancellation number.

First of all, confirm that it will not be received, but this is incorrect, because it is not a question of whether it will be received, but whether it will be sent.

If the mobile phone number has been cancelled, it means that this number does not exist. First of all, the first point is that you will fail to send a text message to this number, because there is no receiver, so the result returned by the operator is failure. SMS verification code is a truth. The verifier sent the verification code to the mobile phone number, but it could not be sent through the operator because it could not be received!
