Viber is a cross-platform messaging and voice calling app used for private chats, group conversations, file sharing, and HD audio/video calls. It works on iOS, Android, Windows, macOS, and Linux. Alongside personal use, Viber offers business messaging, chatbots, and promotional broadcasting tools.
If you want a secure, free-to-use messaging app that works globally without tying everything to your phone number’s ecosystem, Viber offers a solid alternative. Users get encrypted chats, cheap international calling, and strong group messaging features. For businesses, it’s a channel for customer outreach, transactional messaging, and automated support.
Viber uses phone numbers as identifiers but operates over the internet (Wi-Fi or mobile data). Chats and one-to-one calls use end-to-end encryption by default. Businesses can send transactional updates, promote campaigns, or build chatbots via Viber’s Business Messages and Bot API.
