With WhatsApp, you’ll get fast, simple, secure messaging and calling for free, available on phones all over the world.


  • Message your friends and family for free. WhatsApp uses your phone’s Internet connection to send messages so you can avoid SMS fees.
  • Keep in touch with the groups of people that matter the most, like your family or coworkers. With group chats, you can share messages, photos, and videos with up to 256 people atonce. You can also name your group, mute or customize notifications, and more.



WhatsApp’s end-to-end encryption is available when you and the people you message use the latest versions of our app. Many messaging apps only encrypt messages between you and them, but WhatsApp’s end-to-end encryption ensures only you and the person you’re communicating with can read what is sent, and nobody in between, not even WhatsApp. This is because your messages are secured with a lock, and only the recipient and you have the special key needed to unlock and read them. For added protection, every message you send has its own unique lock and key. All of this happens automatically: no need to turn on settings or set up special secret chats to secure your messages.



WhatsApp  was founded in 2009 by Brian Acton and Jan Koum, both veterans of Yahoo. A cross – platform instant messaging application that allows iPhone, BlackBerry, Android, Windows Phones and Nokia smartphones. Users to exchange text, image, video and audio message for free.
