GPRS, EDGE, CSD, HSCSD

With your phone you can use general packet radio service (GPRS), high-speed circuit

switched data (HSCSD), and circuit switched data (CSD). The use of HSCSD services

consumes the battery faster than normal voice or data calls. You may need to connect

the phone to a charger during HSCSD data transfer.

With GPRS, you can stay connected to the mobile Internet and allow faster downloads

without completing a dial-up connection. Applications using GPRS include MMS, SMS

messaging, browsing sessions, e-mail, remote synchronization, PTT, Java application

downloading, and the PC dial-up. Your phone can support three simultaneous

GPRS connections.

Enhanced GPRS (EGPRS, or EDGE) is similar to GPRS but the connection is faster.

To use the EDGE service, subscribe to it from your service provider, and save the GPRS

settings for the functions that you want to use over the EDGE network. For information

on pricing, availability, and data transfer speed, contact your service provider.

When you have selected GPRS as a data bearer, the phone uses EDGE instead of GPRS

if this is available in the network. You cannot choose between EDGE and GPRS, but for

some applications, such as browsing mobile Internet pages, you may be able to select

either GPRS or CSD.

The phone can support three simultaneous GPRS connections.

DEFINE GPRS CONNECTION

Depending on your service, you may be able to define when the phone connects to the

GPRS or EDGE network.

Select Menu > Settings > Connectivity > GPRS > GPRS Connection and one of

the following:

When needed—The phone registers and connects to the GPRS or EDGE network only if

you use a function that needs the GPRS service. The connection closes when you exit

the application. Establishing a connection may take longer than when Always online

is selected.
