Viber Advantages
Free Calls and Messaging
All calls and text messages between Viber users are free. All calls between Viber users take place over the device’s broadband connection, be it WiFi, cellular data, or standard wired broadband in the case of desktop computers.
Hold and Talk
A hold-and-talk button in chat allows users to send short audio messages as part of an IM conversation, giving people a hands-free way to send a comment without having to slow down and type one out.
Public Chats
The Public Chats feature enables a public discussion of up to 100 people to be seen and shared online. Any Viber user can follow a Public Chat but cannot participate unless invited.
