About Viber

Viber lets its users not only make VoIP-based calls around the globe but also share free messages and multimedia attachments. This is one of the most used apps of its kind, offering high quality of communication, even on a 3G connection.

Viber is a free service, available for Android and iOS mobile devices, along with Windows, Mac, and Linux desktop versions. Users pay only for dialing landline and mobile numbers, and the rates vary per country. The main reasons why businesses use this app are for attracting their target audience, marketing purposes, a high quality of communication, and account management.

Viber doesn't require any username and password registration. To make unlimited free voice and video calls, users only need their mobile phone number. The app is easy to install, easy to use, and it runs in the background of a smartphone if a user allows it.
