WhatsApp is a messaging service between mobile phones that can be used as a substitute for text messages that are usually used (SMS). WhatsApp uses an Internet connection to send messages. The service is available for smartphone types whether on iOS, Android, Windows, Blackberry or Symbian.
The major difference between SMS and WhatsApp messages is the fact that these messages are free as long as you use an Internet connection on your phone. However, the application is not completely free.
Use of the application is free for the first year and $ 0.99 per year thereafter. As it uses data, you will also have to pay for data consumption unless you are connected on a free Wi-Fi network.
The application also offers additional functionality via in-app purchases if you want to make non-Internet calls to other mobiles or landline phones. But compared to telecommunications service providers, WhatsApp’s premium service is much cheaper. In addition WhatsApp calls are very clear, especially if both parties have fast Internet connections.
With regard to the protection of personal data, especially the content of messages, administrators assert that there is no fear; that the messages are encrypted and are not stored on its servers.
WhatsApp Inc., was founded in 2009 by Brian Acton and Jan Koum, two former employees of Yahoo !. The company started out as a small start-up and the number of users swelled to 250,000 in a few months; this number was increasing more and more rapidly over time to such an extent that it was necessary to add a charge for the use of the service per year to slow down the subscription rate.
With 700 million users in January 2015, it is currently the largest online messaging application on the market. And as proof, in a year, the number of users amounted to 1 billion, as it was found in February 2016. WhatsApp Inc. is currently based in Mountain View, California, USA; and it is owned by Facebook Inc. since February 19th, 2014 which had acquired it at about $ 19.3 billion.

You can also receive invitations from other friends who have already installed the app on their devices.
