GPRS

General packet radio service. GPRS enables

wireless access for mobile phones to data

networks (network service). GPRS uses

packet data technology where information

is sent in short bursts of data over the

mobile network. The benefit of sending

data in packets is that the network is

occupied only when sending or receiving

data. As GPRS uses the network efficiently,

it allows for quick data connection setup

and fast data transmission speeds.
You must subscribe to the GPRS service. For

availability and subscription to GPRS,

contact your service provider.
During a voice call, you cannot establish a

GPRS connection, and any existing GPRS

connection is put on hold unless the

network supports dual transfer mode.
