This is a bit of a brain dump / diary of what I've discovered about using 3G dongles to send SMS using Python on the Raspberry Pi. Here is how to use Python to send an SMS from the Raspberry Pi via a 3G USB dongle. In order to talk to the dongle, we need to install pyserial wget http://pypi.python.org/packages/source/p/pyserial/pyserial-2.6.tar.gz gunzip pyserial-2.6.tar.gz tar -xvf pyserial-2.6.tar cd pyserial-2.6 sudo python setup.py install Save this file as sms.py - make sure you change …
