GPRS (General Packet Radio Service)
GPRS is a technology that allows the car kit phone to be used
for sending and receiving data over the mobile network
(network service). GPRS as such is a data bearer that enables
wireless access to data networks such as the Internet.
Before you can use GPRS technology, you will need to subscribe
to the GPRS service. For details on the availability of and
subscription to the GPRS service, contact your network operator
or service provider.
For further information, see "GPRS modem settings (network
service)" on page 42.
HSCSD (High Speed Circuit Switched Data)
The car kit phone enables you to use GSM high-speed data
services (network service).
You can use high-speed functionality when your car kit phone
is connected to a compatible computer via Bluetooth wireless
technology and when the modem drivers supporting high-speed
data software are installed on the computer and selected as an
active modem. Modem driver software and installation help can
be found at the Nokia website: http://www.nokia.com.
For information on the availability of and subscription to high-
speed data services, please contact your network operator or
2004 Nokia. All rights reserved.
Remember that the safety of operating a motor vehicle in
traffic requires the full attention of all motorists. Only use
the data transmission features offered by your car kit phone
if traffic conditions permit safe use, and check if local laws/
regulations restrict the use of mobile phones while driving.
Your car kit phone employs the data transmission capabilities of
the GSM network to send faxes, short messages, and e-mails
and to establish connections with remote computers (network
GSM data capabilities of your car kit phone
We recommend that you move the car to a location where the
strongest possible cellular signal can be obtained. A stronger
signal allows more efficient data transmission.
Cellular data communications are subject to a number of
factors that may cause interference:
Radio interference from electronic equipment and devices or
from surrounding traffic may impact the transmission quality.
As the car kit phone user moves from one network cell to
another, the signal strength of the channel drops and the
cellular telephone exchange may hand the user over to a
different cell and frequency where the signal is stronger. A cell
