Glossary
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.
GPS Global positioning system. GPS is a
worldwide radio navigation system.

HSDPA brings high-speed data delivery
