The main difference between texting and using WhatsApp is that WhatsApp is an instant messaging app that allows users to send and receive messages, pictures, videos, documents, and other media, while texting is a form of communication using Short Message Service (SMS) texts. WhatsApp is a data-based messaging service and can be used with Wi-Fi or a mobile data plan without incurring extra charges, whereas texting requires a plan with a texting allowance. Additionally, WhatsApp messages can be sent over various platforms, such as Android and iOS smartphones, whereas text messages are only compatible with one specific platform. Moreover, WhatsApp users can change their status and create groups to communicate with multiple people at once, while texting is limited to one-to-one communication.
