Viber Out is a service that allows Viber users to call any phone number at low rates. You can call landlines and mobiles, even if they are not Viber numbers. This is not free service like VoIP calls on several chat messengers. You have to buy Viber Credit to avail this service. The service price varies from country to country and is much cheaper than what you have to pay cellular operators for similar phone calls. With the release of Viber Out, Windows phone users will now enjoy broader connectivity across several platforms.

With the addition of this critical feature to our Windows Phone 8 version, we are ensuring that the complete Viber experience is available on as many platforms as possible.
