what is gprs?

GPRS is a system of transferring information over the GSM mobile phone network in small packets. E.g. an email would be broken down into lots of little packets of information and then sent over the network. Each packet is given an extra bit of information that tells the network where it is meant to be going and how it fits into the overall structure of the original email. This means that the packets can be routed via different parts of the network taking advantage of spare capacity and re-assembled at the destination in the right order. This is exactly the same method used on the Internet for moving information around.
