platform. While competitors like iMessage or early Android apps focused solely on high-end devices, WhatsApp realized that millions of users in developing markets—such as India, Brazil, and Rwanda—were still using button-based Nokia and Sony Ericsson phones. The Technical Hurdle
To ensure the app functioned smoothly on slow GPRS and EDGE (2G) networks, WhatsApp used a heavily modified, binary version of the XMPP protocol, internally referred to as FunXMPP . By stripping out verbose XML tags and replacing them with compact binary tokens, the app minimized data consumption, saving users money on expensive per-megabyte data plans. 4.
