Apple Begins Rolling Out End-to-End Encrypted RCS Messaging Between iPhone and Android

Apple has started rolling out end-to-end encrypted RCS messaging in beta, a step that allows iPhone users running iOS 26.5 to send encrypted messages to Android users through the cross-platform messaging standard for the first time. The deployment began on May 11, 2026, and is initially available to iPhone users on supported carriers whose Android contacts are running the latest version of Google Messages. The rollout follows the March 2025 publication of the GSMA's RCS Universal Profile 3.0, which established interoperable encryption for the protocol.

The Details

Apple announced on May 11, 2026, that end-to-end encrypted RCS messaging begins rolling out in beta for iPhone users running iOS 26.5 with supported carriers and Android users on the latest version of Google Messages. The company stated that encryption is on by default and will be automatically enabled over time for new and existing RCS conversations, which means eligible users will not need to toggle a setting or initiate a setup process to activate the protection.

The carrier requirements are specific. Apple's carrier support page lists end-to-end encrypted RCS messaging in beta for multiple carriers across the United States and Canada. The documented providers include AT&T, T-Mobile USA, Verizon and Verizon MVNOs, along with several Canadian carriers. The support page indicates that both the iPhone user's carrier and the Android recipient's messaging software must meet the stated requirements for encryption to be active in a given conversation.

When a conversation qualifies for the new protection, iOS 26.5 provides visual confirmation inside the Messages app. The Verge reported that supported RCS conversations with Android users display a lock icon and an "Encrypted" label, giving participants an immediate indicator that the thread is protected by end-to-end encryption rather than the transport-level security that previously covered cross-platform messages. The presence of the lock icon serves as the user-facing signal that both devices and the carrier infrastructure are cooperating under the new encrypted standard.

Context

Apple first introduced baseline RCS support on iPhone in 2024, bringing cross-platform messaging improvements such as read receipts, typing indicators, and higher-quality media sharing compared with traditional SMS. That initial implementation improved the experience of texting between iPhone and Android users but did not include end-to-end encryption for those RCS conversations, which meant iMessage chats between Apple devices remained more private than messages exchanged across platforms.

The encryption capability now rolling out traces its origin to the GSMA's RCS Universal Profile 3.0, which added interoperable end-to-end encryption using Messaging Layer Security in March 2025. Before that standard was published, Google Messages supported end-to-end encryption for some RCS chats, but the protection did not extend to interoperable conversations between iPhone and Android clients because it was not part of the official RCS specification. The gap left cross-platform threads without the same level of privacy that iMessage users experienced when messaging other Apple devices.

In March 2025, Apple told 9to5Mac that it would add support for the encrypted standard in future software updates. Apple said at the time that end-to-end encryption is a powerful privacy and security technology that iMessage has supported since the beginning, and that the company was pleased to have helped lead a cross-industry effort to bring end-to-end encryption to the RCS Universal Profile published by the GSMA. Approximately fourteen months after that statement, the commitment has materialized in the iOS 26.5 beta deployment, closing the privacy gap between iMessage and RCS conversations for users who meet the carrier and software requirements.

What's Next

Because Apple is enabling the feature automatically over time for new and existing RCS conversations, users on supported carriers should see the lock icon appear in cross-platform threads without taking any manual action, as long as their Android contacts have installed the latest version of Google Messages. The beta designation suggests Apple is monitoring performance, carrier compatibility, and user experience before moving to a broader general release.

Industry observers will be watching several indicators in the coming weeks. One is how quickly Android users update to the required version of Google Messages to activate encrypted threads with iPhone contacts. Another is whether Apple expands the list of supported carriers beyond the United States and Canada, which would signal a faster global phase-in. The automatic rollout means adoption will grow organically as users update their software and carriers activate the backend support, but the pace will depend on both mobile operating system update cycles and carrier infrastructure readiness.
