Packet data (EGPRS)
Enhanced general packet radio service (EGPRS), packet data, is a network service that allows mobile phones to 
send and receive data over an Internet protocol (IP)-based network. It enables wireless access to data networks 
such as the Internet.
The applications that may use packet data are MMS, browsing sessions, e-mail, remote SyncML, Java 
application downloading, push to talk, instant messaging, and the PC dial-up.
To define how to use the service, select Menu > Settings > Connectivity > Packet data > Packet data
