I like the Viber app. It is a fine way of connecting with your near and dear without having to worry about payment. Since it is free, its so convenient to call at the drop of a hat and that too instantly. I LOVEEEEEEEEE IT. I have received a 4 digit number from Viber and am supposed to enter it in my acc. where do I do so and how do I do it in Viber.![Smile Smile](https://gsmintro.net/user/images/smiley_images/smile.gif)
