VoIP calls to other users of Viber are entirely free, even if your friends live on a different continent.

Chat logs and history are continuously synchronized between your computer and mobile phone. Viber for desktop essentially acts as a front end for the phone app, although VoIP calls and video chats are made directly from your computer. Once you have the app installed on both your phone and your computer, you can sign in to your account from both locations, and any contacts will be synched automatically. The app is available for iPhone, Android, BlackBerry, Symbian and Windows Phone. In order to use this desktop version of Viber, you must first have Viber installed on your smartphone. This is the desktop version of the more popular mobile Viber app. The program is a VoIP messenger that allows you to make voice and video calls and chat with friends using a large collection of stickers and emojis.

Viber for Windows allows you to call, chat and send SMS messages for free to other users of Viber.
