Packet data, HSCSD, and CSD
With your phone you can use the packet data, high-speed circuit switched data (HSCSD), and
circuit switched data (CSD, GSM data) data services. For availability and subscription to data
services, contact your service provider. See “Modem settings,” p. 50.
The use of HSCSD services consumes the phone battery faster than normal voice or data calls.
