General Packet Radio Service (GPRS) is a mobile data service available to users of GSM mobile phones. It is often described as "2.5G", that is, a technology between the second (2G) and third (3G) generations of mobile telephony. It provides moderate speed data transfer, by using unused TDMA channels in the GSM network. The theoretical limit for packet switched data is approx. 171.2 kbit/s. A realistic bit rate is 30–70 kbit/s. A change to the radio part of GPRS called EDGE allows higher bit rates of between 20 and 200 kbit/s. (from Wikipedia (http://en.wikipedia.org/wiki/GPRS))
