Overview

  • iOS 26 beta code references the Messaging Layer Security protocol and suggests interoperable E2EE for RCS is in development.
  • Apple previously pledged to add end-to-end encryption for RCS across iOS, iPadOS, macOS, and watchOS under GSMA’s Universal Profile 3.0.
  • Google and carrier partners have built MLS support in Android Messages, enabling cross-platform encrypted texting once Apple ships its update.
  • Early tests imply Apple may limit its initial RCS feature set to encryption only, excluding extras like group icons and mentions.
  • Observers caution that the rollout could land in iOS 26 or be delayed to a subsequent update, as no official release date has been announced.
