HSCSD - High-Speed Circuit Switched Data
With the GSM high-speed data service, you can use the Internet and other services more quickly than
usual. For example, Internet connection and sending or receiving e-mail is faster. You can use high-
speed functionality when your phone is connected to a computer via an IR connection or Bluetooth,
and when the modem drivers supporting high-speed data software are installed on your computer and
selected as an active modem.
Note that sending data in HSCSD mode drains the phone’s battery faster than normal voice or data
calls as the phone is sending data more quickly. For continuous usage, connect the phone to a charger.
