WhatsApp is an internet-based messaging platform that allows users to send messages, photos, videos, audio, and more over the internet, which is why it is considered a form of “instant messaging”. Unlike traditional text messaging, WhatsApp messages are actually sent through the internet, which allows messages to be sent almost instantly. Additionally, WhatsApp allows users to create and join group chats, make audio and video calls, and send documents and other files. This can be a great way to stay connected with family and friends, especially when someone is abroad, as using WhatsApp requires an internet connection rather than an active phone plan or sim card.
