Whatsapp

WhatsApp Messenger is a freeware and cross-platform messaging and Voice over IP(VoIP) service owned by Facebook.[44] The application allows the sending of text messages and voice calls, as well as video calls, images and other media, documents, and user location.[45][46] The application runs from a mobile device though it is also accessible from desktop computers; the service requires[47] consumer users to provide a standard cellular mobile number. Originally users could only communicate with other users individually or in groups of individual users, but in September 2017 WhatsApp announced a forthcoming business platform which will enable companies to provide customer service to users at scale.[42]
