WhatsApp is a great choice for messaging because it offers advantages that iMessage does not. Unlike iMessage, WhatsApp is easily accessible across multiple platforms, including Android, iOS, and Windows Phone. Additionally, WhatsApp offers end-to-end encryption to ensure that your messages and calls remain private and secure. Moreover, it also offers cross-platform support for sending pictures, videos, audio, and many more media files. Lastly, WhatsApp also boasts a variety of features like group chats, status messages, and GIFs.
