Apple is reportedly preparing to release significant upgrades to its RCS messaging implementation in the upcoming iOS 26.4 update. The enhancements will bring end-to-end encryption and several modern messaging features that align iPhone’s cross-platform texting capabilities more closely with contemporary messaging standards.
End-to-End Encryption Coming to RCS
Apple confirmed in March 2025 that it would support end-to-end encryption for RCS messaging in a future software update. At the time, the company stated it was pleased to have helped lead a cross-industry effort to bring end-to-end encryption to the RCS Universal Profile published by the GSMA. The feature is expected to be added to iOS, iPadOS, macOS, and watchOS.
When Apple initially introduced RCS support in iOS 18, it implemented version 2.4 of the protocol. This baseline version included fundamental features such as read receipts, higher quality photo sharing, and typing indicators, but lacked encryption capabilities. The encryption functionality only became available with the release of RCS version 3.0, which established the technical foundation for secure cross-platform messaging.
Additional Messaging Features Expected
Beyond encryption, the anticipated update to RCS version 2.7 and above is expected to introduce several feature improvements that will enhance the messaging experience between iPhone and Android devices. These upgrades would bring RCS functionality closer to what users already experience with iMessage.
Anticipated RCS 2.7 Features
- In-line replies to specific messages
- Proper support for emoji reactions
- Custom reactions beyond standard emoji options
- Message editing capability
- Message deletion and recall functionality
Currently, RCS on iPhone handles reactions through a text-based fallback system that displays reactions as plain text notifications rather than as visual emoji overlays. The expected upgrade would replace this workaround with proper reaction rendering similar to iMessage.
Timeline and Carrier Preparation
Evidence suggesting an imminent release emerged in January 2026 when French carrier bundles released alongside iOS 26.3 beta 2 indicated that some carriers will be able to enable end-to-end encrypted RCS messaging by default. This carrier-level preparation typically signals that Apple is nearing public deployment of the feature.
The presence of carrier bundle updates suggests the RCS upgrades are likely to arrive with iOS 26.4, which is expected to enter beta testing later in February 2026. As of the iOS 26.3 Release Candidate, the encryption and advanced messaging features remain absent from the operating system.
Impact on Cross-Platform Messaging
The addition of end-to-end encryption and modern messaging features to RCS on iPhone represents a meaningful step forward for cross-platform communication. While iMessage will likely remain Apple’s preferred messaging platform for communication between Apple devices, these RCS improvements will enhance the security and functionality of conversations between iPhone and Android users.
The ability to edit messages, delete sent messages, and reply in-line to specific messages will bring iPhone-to-Android texting closer to the experience users expect from contemporary messaging platforms. Proper reaction support will also eliminate the awkward text-based reaction notifications currently displayed in conversations.
FAQ
Q: When will end-to-end encrypted RCS be available on iPhone?
A: Based on carrier bundle updates in iOS 26.3 beta releases, the feature is expected to launch with iOS 26.4, which will likely enter beta testing in late February 2026. A public release would typically follow several weeks after beta testing begins.
Q: Will all carriers support encrypted RCS messaging?
A: Carrier support details have not been fully disclosed. Evidence from French carrier bundles suggests some carriers will enable end-to-end encrypted RCS by default, but broader carrier support information has not been confirmed by Apple.
Q: Will these RCS features work with all Android devices?
A: RCS features require both the iPhone and the recipient Android device to support the same RCS protocol version. End-to-end encryption and advanced features will only function when both devices support RCS 2.7 or higher with compatible implementations.
MacReview Verdict
Apple’s forthcoming RCS upgrades represent a pragmatic approach to improving cross-platform messaging without compromising its iMessage ecosystem. The addition of end-to-end encryption addresses a significant security gap in iPhone-to-Android communication, while features like message editing and proper reactions will modernize the experience to meet current user expectations. The timing aligns with Apple’s historical pattern of implementing industry standards while maintaining differentiation for its own platforms. For users who regularly communicate across device ecosystems, these updates should deliver tangible improvements to everyday messaging security and functionality.
