Frontline SMS is a piece of software which turns a laptop computer and a mobile phone or modem into a two-way group messaging hub.
In rural areas in most countries, the mobile phone is the nearest thing to a computer that anyone has. That makes the SMS, which is cheaper than traditional voice calls, the dominant form of communication. So, back in 2005 when Ken Banks was trying to help South Africa’s Kruger National Park communicate and engage with its neighboring communities, it was natural that the solution be provided by mobile phones. Banks recognized this, and elegantly married open-source software to mobile phones to give birth to Frontline SMS — which transforms mobile phone networks into a mass messaging systems.
