 
■ EGPRS, HSCSD, and CSD
With your phone you can use the enhanced GPRS (EGPRS), general packet radio 
service (GPRS), high-speed circuit switched data (HSCSD), and circuit-switched 
data (CSD, 
GSM data
) data services.
For availability and subscription to data services, contact your network operator 
or service provider.
The use of HSCSD services consumes the phone battery faster than normal voice 
or data calls. You may need to connect the phone to a charger for the duration 
of data transfer.
