Viber

When VoIP-telephony lived mostly on desktops, it is difficult to imagine that someone could become a serious competitor for Skype. Even Google failed to solve this task. But now when the VoIP market is rapidly expanding to mobile devices, Skype can't feel so confident any more. Unlike the world of computers (where it was possible to develop single Windows-client), the world of mobile platforms is much more complicated. First, there are many of them, and second - it needs to develop the other VoIP technology. Therefore, the old rivals and even new startups are trying to take on Skype in the mobile VoIP sphere. Viber - is one of the newcomers. This service launched at the end of last year and has already attracted several millions of users. So by means of what Viber is going to beat Skype?
