FrontlineSMS (http://www.frontlinesms.com) is a software tool used in developing countries to monitor elections, broadcast weather changes, and connect people who don’t have access to the Web but do have phones and mobile connectivity. It is the brainchild of Ken Banks, who has probably done more to help people using mobile technology than any other human alive.

FrontlineSMS runs on a computer with a phone plugged into it. The computer and plugged-in phone serve as a hub for SMS (short message service) text communication within a group. People who don’t have Internet access can send in a special code to join the group, after which they receive broadcast messages from the hub. For places with no Internet access, the broadcast hub can serve as a vital connection to the outside world.
