High-speed data calls (high-speed circuit switched data, HSCSD)

HSCSD enables data transmission rates up to 43.2 kb/s, 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 that sending data with HSCSD may drain the battery faster than normal voice or data calls, as the device may send data

more frequently to the network.

GSM data calls

A GSM data call enables data transmission rates of up to 14.4 kb/s. For availability and subscription to data services, contact

your network operator or service provider.
