Viber is a mobile application that allows you to make phone calls and send text messages to all other Viber users for free! Viber is available over WiFi or 3G. Our sound quality is much better than a regular call. Once you and your friends install Viber, you can use it to talk and message as much as you want. Talk, message, and talk and message some more - for free!* You can also call any number that doesn't have Viber at low rates using ViberOut.
Does Viber include advertisements?
