There something called SMS server, with GPRS modem and a data plan, it works like a mobile, this GPRS modem is connected with a software that connecting the web application you've used to send the SMS and the GPRS modem driver, this GPRS modem is like th Fax modem but has a SIM card or it can be a cellular phone connected to the PC both are okay, and the rest is like how mobiles work sending to base station and so on, it's all about the software inside.
