WhatsApp works by allowing users to send messages over a data connection, meaning users don?t have to pay for SMS, explains the official website. The cross-platform messaging application lets users send unlimited audio messages, videos and pictures, as well as creating groups.
WhatsApp enables users to chat with each other regardless of the phone brands they are using, notes the website. Android, iPhone, Windows Phone and Nokia users can download the app to their mobile devices and text each other. The app uses the same data plan an individual uses for browsing the Web or sending emails.
WhatsApp is also available for computer users, and the Web version serves as an extension of a user?s mobile phone account. People who download WhatsApp Web can view all of their messages on both their phones and computers by syncing the devices. WhatsApp advises users to connect to Wi-Fi while using the computer version to prevent data usage charges on their phones.
Users can enjoy WhatsApp for free in the first year and pay $0.99 in the following year, as of April 2015, according to iTunes. The app does not have any hidden costs and also does not charge for sending international messages. Users don?t have to add friends, as WhatsApp syncs with their phone address books and instantly connects with contacts.
