WhatsApp is the most convenient way to send quick messages via mobile phone to any contact or friend in our calendar. The only thing we need is that the person to whom we want to send the message also has the application installed on its own terminal.
Currently WhatsApp is compatible with virtually all mobile operating systems on the market: Android, iOS, Symbian and Windows Phone. That is, through WhatsApp we can communicate with any friend regardless of the terminal model you have.
WhatsApp users can send text messages, voice messages, hyperlinks and images to any user. The compression of images by default also makes the transfer of files very fluid (although quality is obviously lost).
One of the most interesting and used tools of WhatsApp is the possibility of creating and managing groups in a very simple way. Any user can enter any group previous invitation of its creator, and may leave it at any time.
WhatsApp is the perfect communication tool for any Android user, because thanks to it you can stop paying for text messages forever. It is important to bear in mind, in addition, that this application is fully compatible (as far as sending and receiving messages is concerned) with other unofficial WhatsApp tools.
