WhatsApp Messenger is a freeware and cross-platform instant messaging service for smartphones. It uses the Internet to make voice calls, one to one video calls; send text messages, images, GIF, videos, documents, user location, audio files, phone contacts and voice notes using standard cellular mobile numbers. In September 2017 WhatsApp announced a forthcoming business platform which will enable companies to provide customer service to users at scale. All data is end-to-end encrypted. It also incorporates a feature called Status, which allows users to upload photos and videos to a 24-hours-lifetime feed that, by default, are visible to all contacts.
