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 service provider.

Reference information

xRemember 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.

Cellular transmission

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 services).

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:

Noise

Radio interference from electronic equipment and devices or from surrounding traffic may impact the transmission quality.

Handovers

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
