Data connections
Packet data
GPRS (general packet radio service) 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 set-up and fast data
transmission speeds.
You must subscribe to the GPRS service. For availability
and subscription to GPRS, contact your network
operator or service provider.
Enhanced GPRS (EGPRS) is similar to GPRS, but it enables
faster connection. For more information on the
availability of EGPRS and data transfer speed, contact
your network operator or service provider. Note that
when you have selected GPRS as a data bearer, the
device uses EGPRS instead of GPRS if this is available in
the network.
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.
UMTS
UMTS (Universal Mobile Telecommunications System) is
a 3G mobile communication system. Besides voice and
data, UMTS enables audio and video delivery to wireless
devices.
Your device can automatically switch between the GSM
and UMTS networks.
To select which network to use, select Menu > Tools >
Settings > Network and the network in Network
mode. If you want the device to switch between the
networks automatically, select Dual mode.
The GSM network is indicated with
, the UMTS
network with .
When you use your device in GSM and UMTS networks,
multiple data connections can be active at the same
time, and access points can share a data connection. In
the UMTS network, data connections remain active
