Meaning you don’t even need to have friends on the app to use Viber.
They’re public group chats that you can join at any moment. However, the main feature that makes this messaging app stand out is Viber Communities. The service is called Viber Out, and while it’s not free, it’s definitely useful if you’re trying to contact someone who’s not a Viber user. One interesting feature the app has is the ability to call any mobile or landline in the world. You can set it to delete messages in a certain conversation to make sure your private information stays private. When it comes to security, Viber has secret chats that come with a self-destruct timer.
