Connectivity

Your device offers several options (network services) to
connect to the Internet, a corporate intranet, or to
another device or PC. Wireless methods include wireless
LAN, Bluetooth, and infrared. Your device supports a
wired solution with a USB (Universal Serial Bus) cable
connection for Nokia PC Suite. Your device also allows
you to communicate using net calls (Voice over IP), push
to talk, instant messaging (chat), and modem-based
connections.

Packet data (GPRS)

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
54
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.

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
during voice calls. You can, for example, browse the
Web faster than previously possible while
simultaneously speaking on the phone.
