High-speed data calls (High Speed
Circuit Switched Data, HSCSD)
HSCSD enables data transmission rates of up to 43.2 Kbps,
which is four times faster than standard data rates of the
GSM network. HSCSD is comparable to the speed of many
computer modems that communicate with fixed telephone
networks.
For availability and subscription to high-speed data
services, please contact your network operator or service
provider.
Note: Sending data in HSCSD mode may drain the
device’s battery faster than normal voice or data calls,
as the device may send data more frequently to the
network.
