How to Use WhatsApp Messenger
WhatsApp is a cross-platform instant messaging service that has exploded in popularity. In fact, CEO Jan Koum recently boasted that the app was now bigger than Twitter with over 300 million active monthly users and billions of messages sent every day. Among WhatsApp's major selling points is the ease of use of its cross-platform messaging, file and media sharing, as well as the simplicity of creating user accounts (uniquely tied to your phone's SIM card), seamless transitioning between mobile and WiFi data, and contact syncing. Free for the first year of use, WhatsApp charges a paltry $0.99 per year afterwards. Check out our basic run down of WhatsApp's features, as well as a few tips and tricks for making it easier to use.
