VoX Communications has completed development of a downloadable mobile VoIP application for use on Symbian mobile phones.

According to Gartner, 80 million Symbian devices were sold worldwide in 2009, or approximately 47% of the entire global smartphone market. Symbian devices are so dominant in the marketplace today, that it would take the combined sales of the iPhone, RIM, Windows Mobile and Android to equal the same volume opportunity. VoX estimates that its app can be downloaded to more than 100 million Symbian mobile phones that are currently in use. Gartner also projects that Nokia will sell in excess of 100 million Symbian phones in each of the next 3 years.
