If you are looking for a Computer+GSM kinda setup, go for an used GSM phone having IR/USB/serial interface.
is
possible.
Your best bet is to go for some of the older stuff rather than newer modules costing £100+.
I bought from
They sell refurbished modules for £20 each. At that price, they're cheap enough to be used in loads of electronic projects. I've already GSM enabled my home alarm system and central heating units! :D
Another alternative is to use an old mobile phone, but I found that these are not so reliable.
Are units like these available in North America (usa) ??

This model supports GSM 900 and 1800:
That's the modem I bought which works great in the UK. But I don't think these are the right frequencies for the US. You can try the modems on this page:
This is for GSM 850/1900 which I think are US GSM frequencies. I think you also have CDMA.
