Open the call show and send 1 SMS to the server for verification. To which server?

The user must first fill in the mobile phone number and then request to send the verification code. After receiving the request, the server sends a verification code short message to the user's mobile phone. Of course, you should set up your management system (on the server) first. For example, if the user requests a verification code, first, the mobile phone number of ta and the sent verification code are saved on the server.
