Data connections

This device supports packet data (GPRS), high-speed data calls (HSCSD), and GSM data calls.

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 setup 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.

High-speed data calls

HSCSD (high-speed circuit switched data) enables data transmission rates up to 43.2 kb/s, which is four times faster than standard
data rates of the GSM network. HSCSD is comparable to the speed of many computer modems that communicate with fixed
telephone networks.
For availability and subscription to high-speed data services, contact your network operator or service provider.
Sending data with HSCSD may drain the battery faster than normal voice or data calls, as the device may send data more
frequently to the network.

GSM data calls

A GSM data call enables data transmission rates of up to 14.4 kb/s. For availability and subscription to data services, contact your
network operator or service provider.

Mobile VPN

Select Menu Tools Settings
> >
The Nokia mobile virtual private network (VPN) client creates a secure connection to compatible corporate Intranet and services,
including e-mail. Your device connects from a mobile network, through the Internet, to a corporate VPN gateway that acts as a
front door to the compatible corporate network. The VPN client uses IP Security (IPSec) technology. IPSec is a framework of open
standards for supporting secure exchange of data over IP networks.
VPN policies define the method used by VPN client and a VPN gateway to authenticate each other, and the encryption algorithms
that they use to help protect the confidentiality of data. Contact your corporation for a VPN policy.
To use VPN with an application, the application must be associated with a VPN access point. A VPN access point is made up of
an Internet access point and a VPN policy.

VPN management

You can manage your VPN policies, policy servers, VPN logs, and key store password in VPN management. VPN policies define
how data is encrypted for transfer over unsecured networks. The key store password helps protect private keys.
An access point is where your device connects to the network by way of a data call or packet data connection. To use e-mail
and multimedia services or to browse Web pages, you must first define Internet access points for these services. VPN access
points pair VPN policies with Internet access points to create encrypted connections.
To manage VPN, select VPN management
