I'm thinking about embedding a GSM module in a prototype tracking system, but I'm having trouble determining what service providers support GPRS. Do any service providers support this in the US? I know that T-Mobile offers GSM services, I'm not clear on their GPRS support. Do you pay by the number of kilobytes uploaded/downloaded?
I posted this question on alt.cellular too.
Thanks,

AT&T (as of recently, part of Cingular) does.
It depends on your usage plan. I don't know if they have data-only plans, but the "default" data rate is $0.03/kb if you're on a voice plan that doesn't include any prepaid data. They do offer plans with significant discounts on data, apparently - every time I go into GPRS mode on my phone, it asks me if I want to sign up for one of those plans and warns me that if I don't, I'll be charged $0.03/k.
it is aviliable in HONG KONG.

Is you mission in life to piss people off? Go away MY_LINUX, that answer wasn't even an option.......
I was/am/will be looking into M2M (machine to machine) communications using GSM. I was thinking of using a Rabbit Semiconductor solution or bit banging a Coldfire's serial port to control a Wavecom GSM modem.

You'll want to look at this:
It has a dual band GSM/GPRS modem (900/1900 MHz for US Kit, 900/1800 MHz for International Kit) -Brian
