If you get people you need to talk to on Facebook App. The message box for private chats has a phone icon that will call whoever's chat box you are in.. They have to be activated in the app as well.. I called England and USA from Peru and people have called me in USA from around the world.. If they have the face book app for mobile devices, and they activate the call feature, its free.. Its clear with a bit of digital roughness and echo type feedback.. International Free call options are worth knowing about... It only works via face book and only with people on your friends list who have the phone feature activated in their private chat section..
