Somewhat different in terms of use, but the following question probably can get you started with some of the research:

Answer 2

You could download a program called gnokii (I think it works both on Linux and Windows, please check the website). You can connect a very cheap Nokia mobile phone (check the list that are compatible) and send instructions to the cell phone using this program, like sending sms.

I did this some years ago with a very cheap Nokia phone. Of course I had to pay for each SMS sent, but this depends on the plan of your operator.. in my case I bought a SMS packpage for 6 bucks, then I could send 120 SMS (I'm from Brazil, check your location).
