VoX Communications is now offering its mobile voice Android app to Facebook users. Facebook is running millions of impressions a week to promote VoX's Android app. Ads are being shown primarily to college graduates in ten countries. The countries selected are the United States, Argentina, Brazil, Columbia, Egypt, Mexico, Malaysia, Philippines, South Korea and the United Arab Emirates.

A VoX user can subscribe entirely on the phone and choose a U.S. phone number without leaving the interface, which makes the sign up process more elegant than many competitors. The Mobile VoIP paid plans start at $4.95, which is a low cost of entry for a high quality and reliable VoIP service offering. VoX also offers 500 minutes for $9.95 and unlimited calling to more than 60 countries for $29.95 per month. New subscribers can download the app for a free 60-minute trial and make calls to any country on the unlimited calling list.
