Google and Facebook both have products that can translate languages for you and let you chat with people in different countries. While these tools may help you communicate with people outside your country, WhatsApp is also great for communicating with people within your country and with the rest of the world. 

So why should you use it?

The reason is simple: if you have friends in other countries, and you want to talk to them, you will not be able to communicate with them if you use the Google or Facebook translation tool. With WhatsApp, you can send messages to anyone in the world, for free.

You can choose from over 100 different languages for this app, and your messages will be translated with the language you choose.
