Introduced last March, end-to-end encryption for RCS messages on iPhone has yet to be activated in the third beta of iOS 26. Apple is awaiting carrier adoption of the latest RCS standard version but promises features that will make RCS messaging comparable to iMessages.

RCS on iPhone: A Promise of Security and Modernity
Since iOS 18, Apple has supported RCS messaging on iPhones, a technology aimed at modernizing traditional SMS with enhanced features. Currently, Apple supports RCS Universal Profile 2.4. However, the major update anticipated is compatibility with version 3.0 of the profile, which notably introduces end-to-end encryption.
Announced last March, this encryption will finally secure RCS conversations in the same way as iMessage, preventing Apple or any third party from accessing the exchanged messages and attachments. Yet, the third beta of iOS 26 released Monday still has not enabled this feature. Apple must wait for telecom carriers to update their infrastructures to support the Universal Profile 3.0, which explains the delay.
Five Anticipated Updates for RCS Messaging
With the full support of Universal Profile 3.0, iPhone, iPad, Mac, and even Apple Watch users will enjoy a significantly enhanced RCS experience with Android users, coming closer to that of iMessage.
• End-to-end encryption: for total privacy of conversations, similar to iMessage since iOS 5
• Inline replies: to better organize group discussions
• Message editing: quickly correct a mistake after sending (within a given time frame)
• Send cancellation: remove a mistakenly sent message
• Full Tapback compatibility: quick reactions to messages without awkwardness (avoiding the little message that appears ten lines later)
These features will allow iPhone users to have a more seamless experience, even when communicating with Android users, while still keeping SMS as a fallback option when RCS is unavailable.
