Voice over IP (VoIP) is a technology that allows you to make free and cheap calls on the Internet. It allows you to save a lot of money, and often not to pay anything, when calling worldwide. Android is the most popular operating system for smartphones. The two blend perfectly together when it comes to making free calls. 

If you have an Android phone and enjoy Wi-Fi, 3G or LTE connectivity, then you should install and use these apps to communicate with your friends and family around the world without paying anything. Note that for 3G and LTE, you need to consider the cost of connectivity for the data plan.
