Check out the
documentation for a start on the mobile web stuff. It's a start, but it still needs a lot of work. Mobile ASP.NET uses an adaptation model where output is formatted to the device based on a library of device feature support.
While SMS is a mobile technology, it's not really a mobile ASP.NET thing. Messages can be sent from any device. Check out the
support KB 555578 for a code sample and
MXTelecom for a commercial service provider which provides an SMS/MMS gateway.
Cheers,
