The RCS industry standard for enhanced messaging has been updated to officially support standardized End-to-End Encryption (E2EE). Further, Apple has committed to support it in future implementations of RCS in iOS. This will greatly improve the security and privacy of cross-platform messaging between iPhones and Android phones. Google launched its own implementation of E2EE for RCS in 2020, but the feature was not officially part of the RCS standard until now, with GSMA's RCS Universal Profile 3.0. That is why Google's E2EE feature only worked when both parties were using Google's Messages app. Now, this standardized version of E2EE should enable it for more RCS conversations. Apple has not committed to a specific timeline for adding E2EE to RCS.
