Hi guys

Im trying to find some HW for a project in which I want to take data from GPS and accelerometer and send to my server via modem (3G). I have seen SoC solutions (e.g. Telit) but really expensive! So far it has not been possible for me to find a cheap SoC solution (<50$).
I've also seen http://wm.sim.com/ but it's not easy to buy the chip from this supplier.
It has to be an embedded solution and I want it to be as cheap as possible.
Unfortunately I cannot find any good and cheap modem chips to buy on the market. I know there are a lot of Chinese and asian suppliers but I dont know how to approach this.
Can you please give me any advice on where or how I can find stand-alone modems to connect to a microcontroller?

Thanks.

$50 goal seems a bit unrealistic even excluding the GSM part. The last time i checked just a crappy GPS chip without antenna was about $20. Now count in the price of the PCB in single quantity, antenna, perhaps a battery, case and a bit of this and that, and you get over your budget fast.

From looking around, gps and 3g is not going to happen for 50 USD.

Here is interesting option if you are using Arduino: http://www.cooking-hacks.com/3g-gprs-shield-for-arduino-3g-gps
