The best thing about this app is that it works even without internet connection; I was in Syria when my wife sent me a message asking for help but we couldn't communicate because there wasn't any wifi network available to connect. With all her worries at hand, she decided to use this app so we could stay connected through our phones. It's been days since she last heard from us. If you are looking for something reliable then go ahead try out this product. We needed to keep each other updated while being thousands of miles away. This application allowed us to do just that.
