If you are an expat you'll agree that when we are connected to Internet we are not in the mood to call our relatives at home - and when we are in the mood to do it, we don't have a good Internet connection.
Thanks to this app I understood that I was losing the connection with family and friends!
Now I can call home when I am moving by car, train or whatsoever, because I can call with normal mobile calls (without using data), always at local rate, worldwide!
