Apple’s iOS 26.4 will bring major Messages upgrades including enhanced RCS texting, expanded privacy, cross-platform features, and security.
Apple is lining up one of the most consequential updates to its Messages app in years with iOS 26.4, expected to roll out this spring. The update significantly expands Apple’s support for RCS (Rich Communication Services), signaling a deliberate move away from the limitations of traditional SMS and toward a modern, cross-platform messaging experience that better reflects how people actually communicate today.
RCS is the telecom industry’s long-promised successor to SMS and MMS, designed to deliver features users now take for granted in modern chat apps. It enables high-quality media sharing, read receipts, typing indicators, and reliable delivery over Wi-Fi or mobile data. More importantly for iPhone users, RCS narrows the long-standing gap between Apple’s iMessage ecosystem and Android devices, replacing the fragile “green bubble” SMS experience with something far closer to native chat.
