Answer 1

Most GSM modem will come with a library of it's own. You don't really need the library to be written in C#. Generally it will be in dll or exe. If it's a dll written using C++, you can still call it's function via p/invoke. You just need to know the function signature in order to send and retrieve data from it properly. Check the documentation. If it's an exe, most likely it commandline based, then you can call it by using Process.Start() and putting in what ever you want to send via the argument.
