WhatsApp Messenger allows you to send text messages, images, video, audio, and even make calls using the Internet connection of your mobile device (including support for Android Wear).
WhatsApp is a multi-platform messaging service available on most mobile operating systems, as well as Windows and Mac. If you'd like to use WhatsApp for PC on your computer, download it here.
With WhatsApp you can also make calls for free, even when your friends are located in a different country.
Calls are free because the app uses your internet connection, like Skype, instead of your carrier's call network.
Therefore, if you are not connected to WiFi, WhatsApp calls will use your data plan.
