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
ha ve s ele cte d GP RS a s a da ta 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.
Mobile VPN
Select Menu > Tools > Settings > Connection > VPN.
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 > Options >
