Singaporean startup launches free VoIP for 2G

The Nanu app plays sponsored ads before a call, letting users make free calls to other app users, as well as landlines and mobiles not using the app.

Gentay Communications, a Singapore-based startup, has just launched Nanu, an Android app capable of making VoIP calls even on low-bandwidth 2G connections.

This means that, in theory, the phone should be able to work in rural areas where 3G isn't available. The app lets you make app-to-app calls, as well as calls to landlines and mobile numbers.

Instead of charging customers to make a call, Nanu will be using sponsored ringtones to offset the cost. This means that calls are free, even to the aforementioned landlines and mobile numbers -- though the catch is it's only for 15 minutes and only for the first million who download the app.

As more users sign on, advertising revenue will grow, which will allow Nanu to subsidize more calls and add more free minutes.

I gave the app a quick test, and found that while on 2G, I could hear the other party clearly, but I was constantly breaking up on their end. On 3G, it was much better.

The Nanu app is currently available on the Google Play Store, with iOS to follow soon. There are also plans to make the app available for the Mac and Windows.
