 
GPRS, HSCSD and CSD
You can use GPRS (General Packet Radio Service), HSCSD (High Speed Circuit 
Switched Data) and CSD (Circuit Switched Data, 
GSM data
) data services.
For availability and subscription to high-speed data services, contact your 
network operator or service provider.
Note that the use of HSCSD service consumes the phone’s battery faster than 
normal voice or data calls. You may need to connect the phone to a charger for 
the duration of data transfer.
