WHATSAPP

WhatsApp Messenger is the most convenient way of quickly sending messages on your mobile phone to any contact or friend on your contacts list. The only requirement is that the other people must have the app installed on their own device

Currently, WhatsApp is compatible with just about all mobile operating systems on the market: Android, iOS, Symbian and Windows Phone. So this basically means you’ll be able to use WhatsApp to communicate with any friend, regardless of what model of device they have.
