Viber is one of the favourite app. But i gave you 4 Stars. Reson : We cant send private messages in the app. I mean we cant send messages without show number. If we send message they are always chat with us. And if we block them after they use another number to chat me. This is the probleam im Faced. Other wise is good. I Love The app. ❤️💙🧡💚🤎💛.
