Viber Allows You to Call & Text For Free!

Viber is an application for iPhone® and Android™ phones that lets you make free phone calls and send text messages to anyone who also has the application installed. This app makes it very useful for communicating with other teaching colleagues from all over the world (Relatives, businesses, schools, whatever) I personally haven't tried it yet, but if you have used Viber, please give us your feedback.
