Depends on carrier. IIRC (someone feel free to
correct me), most
modern phones that have serial USB or Bluetooth profiles (most Nokias
and Motorolas do) support CSD (Circuit Switched Data), so serial data
is not voice-band modulated at the phone, but sent to the carrier
digitally, then modulated at their switch.
I used to use a Sony-Ericsson T610 as a bluetooth modem on my
PowerBook, through T-Mobile.
If the GPRS data service was not available, I could send it AT
commands and use it as if it were any other modem. Dialup through the
GSM service was good for 9600 BPS.
