Great calling service to land line internationally – Ringo: Low cost calls Review

This app is great to call international land line. I use this to make reservation at restaurants, to make company inquiries, and to call people who does not use smart phones. It expand my convenience greatly while I was traveling places in Japan. Also, just $5 will stretch long long way to keep using this app.
