Google and Apple have begun rolling out end-to-end encryption (E2EE) for Rich Communication Services (RCS) messaging between Android and iPhone users, marking a significant shift in cross-platform privacy that addresses the longstanding lack of encryption in standard SMS texts.
The feature is currently rolling out in beta today. Android users must have the latest version of Google Messages, while iPhone users must be running iOS 26.5 with a supported carrier. Encryption is on by default for cross-platform RCS chats. Users will see a lock icon in their conversation threads, similar to the indicator used for Android-to-Android encrypted chats, requiring no manual setup.
The encryption protects message content from being intercepted in transit, ensuring that no third party, including Google, Apple, or carriers, can read the messages. The feature currently applies only to RCS conversations; if RCS is unavailable, messages fall back to unencrypted SMS. Group chat encryption across platforms and support for Google Voice or third-party RCS-enabled apps may have varying availability.
While Apple added RCS support to iOS last year to improve interoperability with Android (providing features like read receipts and high-res media), it previously lacked end-to-end encryption. This rollout closes the security gap where iPhone-to-Android texts were vulnerable to eavesdropping, unlike encrypted iMessage chats.
This development is the result of a cross-industry effort led by Google and Apple to standardize secure RCS messaging, building on Google’s previous implementation of E2EE for Android-to-Android chats using the Signal Protocol.
