if it sounds too good to be true... according to reviews "unless both sides are registered with the app there are just 15 mins of free calls"

@_jacksmith I totally agree, but assuming this were true and the service is functional, this has got to be one awesomely innovative idea. I mean the possibility this has in emerging markets such as Indonesia, Phillipines, South America are huge, the guys behind it are from Singapore. They say that they make the service possible with a ad based ringtone, but in theory this would work but I think there would be a time cap at some point... Definitley interesting...

@acondurache agreed. 2G network must be super cheap for the cellular guys to maintain. I see calls over wifi as the most logical step for facilitating free calls though; as it's not monopolised what you can do with it, as much as the phone companies. see http://www.producthunt.com/posts...

@_jacksmith the founder says that the tech behind it is ".. VoIP technology and was originally developed to support ship-to-shore voice communications for the maritime industry, which typically run on low bandwidth over satellite.." . Wifi would seem logical in developed economies, however this has a lot more potential in emerging economies that do not have a large distribution of wifi enabled devices (i.e. no smartphones and no hotspots)

Hello there, just to revive the thread. Sorry took me a long time @_jacksmith @acondurache The service is more stable now, fortunately! We pay for the termination fees from the bulk telco providers. The innovation is using VoIP even on 2G. Developing markets definitely picked it up and we gained half a million users just within 2 months of launch. We had a few more learnings along the way to ensure its performance. We offer non-nanu calls to mobile and landline in 48 countries so far (the cap that we can afford the termination costs for now) hence we have that 15 free minutes upon registration and we added 3rd-party app offers to get more minutes. Beyond that, app-to-app calls are unlimited for free.
