Getting started with Kallber is quick and easy.
In a hurry? Sign up with Facebook.
We have apps for iPhone, Android and Windows Phone. You can also use Kallber on other phones.
Your first call is free so you don´t need to pay a cent until you've tried the service.
This app is so easy to use, it syncs with your phone (for people using it on their iPads like me) so all your calls and numbers are available. LOVE IT!

50% cheaper than Skype!! Definitely the best voice quality for international calling on 3G and Wifi out there right now. Better quality than Viber!

I'll spend a minute on this because Kallber simply rocks. I warmly recommend this service. Fair price and great quality always.
