Did something similar in Africa 10 years ago. We created a whole human writable protocol, carboards to help, and you could control the systems using nokia 3310 charged on a car battery in the middle of the Dogon desert. Fun times. Also, thanks python for making it way easier than it should have been. GPRS modems are not simple beasts.
