■ 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
).
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.
