Question : sms gateway in asp.net

Hello, I have a website with too many audio songs, I want to let the visitors to download that songs as ringtones on their mobiles, to get the request from the visitors i had planned to ask them to send an sms with a code for the song which they desired to have like a ringtone. (this is my idea if there is any other ways to do so please tell me). and to do the further process i need a specific destination, i mean i  need a number to give to the visitor to send their request (actually i donno how to get that number also), after getting the request from the visitor application should search for the song with the code that been sent by the visitor and needs to send a link or the song to let the visitor to download the song to their mobile.
I need to do this but i dont have an idea to how to do it..and i also dont know how i can call it,but I named it as sms gateway. so please help me in doing this or give some tutorial links so that i can learn.
Thanks in advance.
