With over 1.5 billion Series 40 phones sold since the platform was launched, this is a huge step on Viber’s path to become the first truly global VoIP client.
While Microsoft’s multi-billion acquisition Skype might be the first VoIP app to come to mind, it’s a demanding app available on modern smartphones like iOS, Android and Windows Phone. Viber is also available on those platforms plus RIM’s BlackBerry, works quietly in the background at all times and is coming to over 1.5 billion of feature phones, satisfying the developing world’s need for free calls.
Viber is also unveiling new functionality for its existing apps - the Windows Phone version of the app is now adding support for 720p HD video calling.
Finally, Viber has been growing steadily since the first day of its launch in late 2010. In February, it hit 50 million, in May the number grew to 70 million and right now, there are more than 100 million Viber users across the globe making 10 million free calls a day. Not bad for an app that’s less than two years old, is it?
