Apple to Introduce Encryption Capabilities for RCS Messaging

Nearly a year has passed since the GSM Association announced the RCS Universal Profile 3.0. One of the most significant additions in this release was standardized end-to-end encryption (E2EE) system for RCS messages. Prior to this update, RCS encryption was only available through Google’s proprietary implementation. Because this approach was exclusive to Google and not an industry-wide standard, Apple did not support it when introducing RCS messaging in iOS 18.

Now that an industry-wide standard for RCS encryption is in place, Apple has begun working on implementing it. This change will eventually allow Android and Apple users to exchange encrypted messages with one another. However, Apple does not appear to be moving quickly ,as nearly a year has already passed. Even so, signs that Apple is preparing this feature have surfaced in iOS 26.3 Beta 2.

It remains unclear whether the software currently supports end-to-end encrypted (E2EE) messages. What has been discovered so far appears to be limited to parts of the user interface, which inform users about the encryption status of their messages and allow them to adjust encryption-related settings.

End-to-end encryption (E2EE) could be introduced with the stable release of iOS 26.3 or it may be postponed until iOS 27. Apple has not made any official statements or confirmed a timeline for rolling out support for Version 3.0.

It is important to note that the encryption not only secures text messages but also extends to files shared over RCS including photos, videos and other types of attachments. This enhanced level of security applies equally to group chats ensuring that all participants messages and shared content remain fully protected.

Beyond encryption the RCS Universal Profile 3.0 introduces several enhancements to improve the messaging experience. Users can now reply directly to specific messages inline, edit messages after sending and unsend messages within a limited time frame. Additionally Tapback support allows users to add emoji reactions to messages in an official and reliable way rather than relying on the previous workaround which was not fully supported.

It is worth noting that the GSM Association has already released the specifications for the Universal Profile 3.1 which build upon the previous version with several important enhancements. Among the new features are support for a higher-quality audio codec (xHE-AAC) improved tools for reporting spam messages, stronger security measures for transferring files, and better performance in situations where network connections may be weak or unreliable.
