Apple to Introduce Private RCS Messaging on iPhone, Boosting Cross-Platform Security

Apple is preparing to roll out a major upgrade to its Messages app with the introduction of end-to-end encrypted Rich Communication Services (RCS), marking a significant step toward improving privacy in cross-platform messaging between iPhone and Android users. The feature is expected to arrive with the upcoming iOS 26.5 update, which is likely to be released in the coming days.

According to Apple’s official release notes, the new update will bring end-to-end encryption (E2EE) for RCS conversations, ensuring that messages exchanged between iPhone and Android devices remain fully secure and inaccessible to third parties. However, the feature will initially be available in beta and only supported by select carriers, with a gradual rollout planned across regions.

RCS messaging is considered the modern successor to traditional SMS and MMS, offering features such as typing indicators, read receipts, high-resolution media sharing, and improved group chats. Until now, while Apple has supported RCS on iPhones, conversations between Android and iPhone users lacked full encryption, leaving a gap in privacy compared to Apple’s iMessage system.

With iOS 26.5, Apple aims to close that gap. The new implementation ensures that RCS messages will be protected using end-to-end encryption, meaning only the sender and recipient can read the content. Even Apple or mobile carriers will not have access to the messages. Encrypted chats will be clearly marked within the Messages app, and users will also have an option in settings to verify or manage encryption preferences.

The feature has been developed in collaboration with the GSM Association (GSMA), which oversees global RCS standards. It is based on the updated RCS Universal Profile 3.0, which includes advanced security and interoperability enhancements. This update aligns Android and iPhone messaging security levels more closely, particularly for cross-platform conversations.

Apple has already been testing encrypted RCS messaging in earlier beta versions of iOS, iPadOS, macOS, and watchOS. However, full cross-platform encryption is now expected to be part of the stable iOS 26.5 release, though it will still be labeled as a phased rollout depending on carrier readiness.

Apart from encryption, Apple is also expected to introduce additional enhancements in the update, including improved messaging features and system-level refinements across the iPhone ecosystem.
