VoX mobile VoIP is a cloud-based service that allows users to call free in-network and make cheap calls to landlines and mobiles worldwide. Parent company Pervasip Corp. recently announced that the World Prepaid Phone Card from VoX is now available and has been shipped to distributors in California, Florida, Michigan and Washington.

“Our distributors have placed the card in several retail stores and we are seeing revenue growth from the launch of our calling card product,” said Paul Riss, Pervasip’s CEO. “We are beginning to see the VoX logo in store windows and we are pleased with the initial reception we have received.”

“We are also working with calling card companies directly, who want the low calling rates and no connection fees for their customers,” continued Riss. “Our strategy is to use our calling card product as a technique for introducing the calling card distributors to our mobile app. We believe we can help these companies transition to a digital product as consumers flock to smart phones and other mobile devices.”

The VoX mobile VoIP app allows both voice and video messaging and has racked up over 160,000 downloads with almost no marketing driving its growing popularity. The company has an iOS application coming soon (as soon as today if Facebook hints as of late are any indication), with Windows Phone and BlackBerry 10 versions planned in late 2013 or early 2014.

The VoX mobile VoIP app can be downloaded directly from Google Play.
