Mobile calls app

Vonage Mobile: This app is the mobile version of the well known internet calls company. With this app you can call and text for free anyone in the world as long as they have the app installed on their phones (even IPhones). App-to-App calls are made using high-definition audio which provides better voice quality than traditional cell phone calls. The app works over Wi-Fi, 3G and 4G data networks worldwide. You do not need to be a Vonage phone service customer to use the app. If you want to call someone who doesn't have a cell phone or a land line that is a paid feature, but they offer lower rates than any international carrier. Here's the link. From the phone search for "vonage mobile" and install.
