Viber

What Viber is

Viber is a free calling and messaging app for Android, iOS, Linux, macOS, and Windows. People can exchange texts, photos, videos, files, voice messages, and video messages, and make voice, video, and group calls. Group chats hold up to 250 people; Communities can have unlimited members, hide members’ phone numbers, and offer admin moderation controls. Community and channel admins can also connect bots to help manage or interact with those spaces.

Chats sync across mobile, tablet, and desktop, and calls can be transferred between devices. Desktop activation requires an active Viber account on a mobile phone. Viber says one-to-one and group chats use end-to-end encryption by default, with encryption keys stored on users’ devices. Privacy features include disappearing messages, hidden chats, message editing or deletion for everyone, and controls for online and delivery status. Viber Out supports calls to phone numbers outside Viber, with rates varying by destination. Viber Plus adds an ad-free experience, privacy and customization features, and live chat support; its price is shown in the app.
