Prsww - cheapest calls (Unreleased)

PRSWW is the cheapest VoIP service for national and international calls. Mobile VoIP has never been that easy. Use your Wifi or data plan (3G/4G) to make VoIP calls with your phone or tablet. The App doesn’t use any minute of your mobile service provider. When you call, PRSWW bypasses you regular carrier and makes VoIP calls using your phone or tablet’s Internet connection ( no more roaming fees). PRSWW works anywhere as long as you have a good 3G/4G or Wifi connection.
