Viber, or Rakuten Viber, is a cross-platform voice-over IP and instant messaging software application owned by the Japanese multinational company Rakuten.
At the beginning of the smartphone era, Viber was one of the top messaging apps in the world battling with Whatsapp.
Now I don’t know a lot of people that still use it and it’s a pity because it works pretty well, video calls, sending pics, and chats can be sent for free.
If you had Whatsapp or other phone numbers and accounts banned you might opt for Viber as an alternative to be closer to your fans and family.
