C# How to Call Fetion to Send SMS

There are generally two ways to send short messages by fetion. You can download Fetion's mobile phone client directly. After logging in, Fetion will send two modes, message mode and short message mode. What you send in SMS mode will be received by the other party in the form of SMS.

In addition, you only need to download the latest version and the content sent by Fetion and Fetion after downloading, whether in message mode or super short message mode. If the other party's default client is online, then when the other party's target client is not online, it will end in the form of SMS by default, and you don't need to switch the sending method.
