This seems to need a computer to actually send the SMS. Would've been far more flexible to buy a cheap AT GSM modem.

But a lot more expensive

Does anyone know of a cheap and simple SMS only GSM modem?

All the ones I have used were expensive industrial spec units with complex data channels.

You can hack this module: http://finch.am/projects/arduinogsm/ $25

OR you can buy this arduino shield: http://www.sparkfun.com/products/9607 $100

I know it's "just" an arduino talking to another PC .. but after doing some drilling, soldering, glueing, screwing and general arduino-ing myself ( http://www.youtube.com/watch?v=N9Rj-NegE6E ) well done on actually getting something designed, done and "ready". If you inspire one person to pick up an arduino then that's compliment enough !

Huawei GTM900

Has serial port which takes AT commands. Easy enough to drive it.

Costs $20 a shot.

If it doesn't have to be SMS only, there are various mass market "surf sticks" offered by providers on the cheap, marketed at laptop owners and the like. Many of them are just AT modems with serial ports tunneled through USB and then controlled by an application on the computer.

Thanks, I assumed those would need a whole series of windows drivers to initialise them. But it looks like you can just jumper straight to the RS232 interface on this chip

This project's pretty awesome.

The cheapest way to solve the issue would be to hook it up to something like a nokia pay as you go phone over serial/bluetooth.
