The problem in a predominantly pre-paid phone connection market like India is that caller identities are often a mystery. So people end up taking a lot of unwanted calls and spam. That’s why an app like TrueCaller, developed in Sweden, is more popular in India than in the West.

Now there’s a new app called Holaa!, just launched today, which claims to help smartphone users manage their calls better. It’s a product of Nimbuzz, which shifted its base from the Netherlands to India in 2012 to serve a growing Indian user base for voice over IP (VoIP), messaging, and mobile advertising services.
