Transceivers, Cell Phones, and RS-232.

Transceivers, Cell Phones, and RS-232. Ok, here is my situation, I would like to have my computer communicate large distances to a Microcontroller. I can find simple RS-232 transceivers that will get the job done, but will only communicate a distance of 20 Meters. I found one company that www.maxstream.com that sells RS-232 RF modems that can go up to 30 miles (if you have an extreme antenna). But I would like to communicate with my MCU device over greater distances. Perhaps 100 miles, but it is within a cell site. I don’t mind using a cell phone, but I don’t know how. Could anyone help me out here?
