General Packet Radio Service is a wireless data transmission service based on packet transmission. For example, if an email is sent by GPRS it will be reduced into .packets. of information. Each individual packet travels to its destination by the quickest possible route. This means the different packets from the same mail can travel separately through foreign networks around the globe in order to avoid obstructions. At the pre-set destination they are rebuilt and presented to the recipient as a whole. GPRS offers instant access, and permanent connection between the mobile device and the network. With GPRS you only pay for information sent or received, rather than for connection time.
