Apple Brings End-to-End Encrypted RCS Messaging to iPhone and Android with iOS 26.5

Nearly 18 months after the FBI warned Americans about the security risks of texting between iPhones and Android devices, Apple has introduced end-to-end encrypted cross-platform messaging through iOS 26.5, according to Forbes.

The update enables encrypted RCS messaging between iPhone and Android users for the first time – though Apple has noted that the feature “is not available to all.” Availability depends on both device compatibility and carrier support, meaning some users may not gain immediate access to secure RCS messaging even after installing the update.

The carrier dependency is a key distinction from platforms like WhatsApp, where end-to-end encryption is always active because the app controls both sides of any conversation. Apple’s and Google’s implementation of encrypted RCS, by contrast, relies on carrier infrastructure – which introduces variability depending on the networks connected to both devices at any given moment.

For context, Apple’s iMessage has long offered fully encrypted communication between Apple devices, identifiable by the familiar blue chat bubbles. Messages sent outside that ecosystem — the green bubble conversations – fall back on SMS or RCS protocols. With Google Messages, encrypted RCS has been available when all participants are using updated versions of the app, though users need to verify whether encryption is actually active in any given chat.

Encryped RCS messaging to follow

In its release notes ahead of the update, Apple stated that “end-to-end encrypted RCS messaging (beta) in Messages is available with supported carriers and will roll out over time,” adding that a list of supported carriers would be published on its messaging support page.

Given the carrier dependency, Apple and Android users looking for consistent, reliable encryption may still find services like WhatsApp or Signal more dependable, or simply stay within their respective ecosystems where encryption is guaranteed.

Industry observers had anticipated iOS 26.5 would arrive this week, bringing encrypted RCS alongside broader improvements to performance, battery life, and system stability. German technology outlet Born City reported that Apple’s upcoming iOS updates are partly a response to longstanding criticism of the closed iMessage ecosystem, growing demand for AI features, and rising regulatory pressure. India-based publication Eastern Herald framed the RCS rollout as part of a wider industry effort to reconcile privacy with cross-platform interoperability.

Apple officially launched the encrypted RCS feature in beta on May 11, describing it as a joint initiative with Google aimed at making RCS – the modern successor to SMS – more secure across platforms.

“Starting today,” Apple said, “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.”

Users on supported carriers will see a lock icon appear in RCS conversations when encryption is active. Apple confirmed that encryption is enabled by default and will gradually extend to both new and existing RCS conversations over time.

The move represents one of the most significant shifts in text messaging in decades, potentially closing much of the gap between standard cross-platform texting and the kind of security that encrypted messaging apps have offered for years. Analysts, however, point out that it remains to be seen how quickly carriers around the world will adopt the protocol, and whether the change will meaningfully challenge WhatsApp’s grip in markets where it dominates.

What’s clear is that the rollout directly addresses the U.S. government’s earlier concerns about unencrypted cross-platform communication – and delivers what many users have been waiting a long time for.
