WhatsApp Messenger is a freeware and cross-platform messaging and voice over IP (VoIP) service owned by Meta.[9] The application allows the sending of text messages and voice calls, as well as video calls, images and other media, documents, and user location.[10][11][12]

In September 2017 WhatsApp announced a forthcoming business platform which will enable companies to provide customer service to users.[14]
