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.
