The world's most-used messaging app and the default contact method in many countries.
- Global
Viber is a messaging app with a substantial user base in Eastern Europe, Greece and parts of Southeast Asia, where it holds positions that WhatsApp occupies elsewhere.
Beyond chat it offers calls to landlines and mobiles at low rates, community channels for large audiences, and business messaging for transactional notifications.
Its relevance is regional rather than global: worth using where your audience already is, and worth ignoring where they are not.
