What do you mean, the SMS configuration is not filled in, and the verification code cannot be sent out?

The reason for this situation is that the configuration of SMS server is not perfect, and the sending of verification code depends on SMS gateway.

1. The configuration of the SMS server is imperfect: for example, the server address, port, user name and password are missing, which makes it impossible to establish a normal communication channel with the SMS server.

2. The sending of the verification code depends on the SMS gateway: if the SMS gateway information is configured incorrectly or is under maintenance, the verification code will not be sent normally.
