As we know there are various free calling apps are present by which we can call for free over the internet but are all working perfectly using the 2G network? No. Maximum all apps worked perfectly using wifi or 3G or they need strong connection. Nanu is an app which will run perfectly in 2G also, so now you can call on any nanu user over 2G for free.
What's revolutionary about nanu? Well first of all, nanu doesn't need a fast network so it works on 2g and congested networks too. In other words, it works anywhere your phone does (in the elevator, the subway, the car etc). Plus nanu sounds crisper and clearer.
