■ 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,
services. For availability and subscription to data services, contact your
network operator or service provider. See “Modem settings,” p. 50.
The use of HSCSD services consumes the phone battery faster than
normal voice or data calls.
