Nearly a year ago, the GSM Association introduced the RCS Universal Profile 3.0, which incorporates an end-to-end encryption (E2EE) standard for messaging. Previously, end-to-end encryption was a Google-specific feature, which is why Apple refrained from supporting it when it integrated RCS with iOS 18.
With the establishment of an industry standard, Apple is now working on its implementation. This move will finally facilitate encrypted messaging between Android and Apple devices. Despite the significant delay—almost a year—initial indicators of support have surfaced in the iOS 26.3 Beta 2.
It remains unclear whether the software currently supports E2EE messaging. However, components of the user interface have been discovered, which will indicate the encryption status to users and permit adjustments to their settings.
The rollout of E2EE could coincide with the stable release of iOS 26.3, or it may be pushed back to iOS 27. As of now, Apple has not provided any official timeline for the implementation of Version 3.0.
The encryption feature not only safeguards text messages but also protects files—including photos, videos, and more—that are shared via RCS. This functionality extends to group chats as well.
Moreover, the new RCS Universal Profile 3.0 offers various features beyond encryption. These enhancements include inline replies, message editing and un-sending (within a limited timeframe), and improved Tapback support, which allows for emoji reactions—currently implemented in a makeshift manner.
Additionally, it’s worth noting that the GSM Association has already released the Universal Profile 3.1 specifications, which entail upgrades such as support for an advanced audio codec (xHE-AAC), spam reporting capabilities, enhanced file transfer security, and improved reliability under unstable connections.
