WhatsApp Messenger is a mobile application designed for smartphones that can be used for chat, text and voice messaging, share pictures or location and more.
The difference between this app and a mobile carrier is that all data transmitted (SMS, voice messages, files etc.) are sent via WhatsApp servers and you will not pay mobile carrier fees. All you need is an internet connection (ideal is a WiFi one).
Can chat with groups of friends, send any messages, audio and other data you want.
Is one of the most popular application for free messaging with large number of users. All recipients must have WhatsApp installed on their phones.
