■ Packet data, HSCSD, and CSD
With your phone you can use the packet data, HSCSD (high-speed
circuit switched data), and CSD (circuit switched data, GSM 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.
