• turn your Android phone into a true,free,open... communications device - anytime, anywhere.

Here's the description : ''Mobile communications are useful, but depend on infrastructure that can be damaged, overwhelmed, or even absent. So we assumed zero infrastructure, and came up with this; just the phones talking to each other, relaying calls, and resolving numbers for each other; a cellular commons using our unique Serval Mesh telephony software. We have developed mesh software that uniquely allows you to use your existing phone number.
So with using your existing number, and not requiring Internet Access, our software is making the best of what you have, whether in a disaster or emergency situation, or where poor economies or regional & location restrictions can mean zero infrastructure, we enable communication using just existing mobile phones. Our software is :
* Completely open and open-source; free for all
* Can be carried and activated in seconds by those who need it when it is needed
* Carrier independent
* Can be retro-installed during an emergency
* Distributed nature makes network resilient

Ideal for remote, rural impoverished communities, and disaster/emergency situations, and the services that support them, our software is making the best of one of the most ubiquitous of devices - the mobile phone.''
