Quick answer. Yes, Apple supports RCS on iPhone. Apple added RCS to the Messages app starting with iOS 18.1 in late 2024, ending years of iPhone-only SMS/MMS fallback for messages to Android. In May 2026, iOS 26.5 added end-to-end encryption to cross-platform RCS by default (in beta), built on GSMA Universal Profile 3.0. Apple's RCS support depends on the carrier, and availability has been expanding country by country; the three major US carriers all support it, including the encrypted version.
Apple's support was the inflection point for RCS: it brought the standard to virtually all modern smartphones in markets like the US and triggered a major surge in RCS traffic. Apple still keeps iMessage as its own encrypted service for Apple-to-Apple chats, with RCS handling messages to Android and business senders.
