At Rakuten Viber, we connect people–no matter who they are, or where they are from. As a communication platform that connects hundreds of millions of people around the world, we know that the way people communicate changes on an almost daily basis. That's why we dedicate ourselves to providing added value to communication — from private and group chats to audio and video calls to the ability to follow and contact brands, businesses and celebrities.
Viber is an all-in-one platform for everything communications-based, and all Viber communications are protected by end-to-end encryption.
