GPRS (General Packet Radio Service) is a packet-switched wireless communication service. GPRS is based on GSM and existing services such as circuit-switched cellular phone connections and the Short Message Service (SMS). GPRS is charged per megabyte of transferred data, while traditional circuit-switched service is billed per minute of connection time, independent of whether the user has actually transferred data or has been in idle state. GPRS is also known as 2.5G, a technology between the second (2G) and third (3G) generations of mobile telephony.
