That tiny lock icon you already trust in iMessage is about to get more useful — and a lot less one-sided.
Apple's release candidate for iOS 26.5, distributed to developers and public testers this week, announces native support for end-to-end encrypted RCS conversations between iPhones and Android devices. The changelog is blunt: “End-to-end encrypted RCS messaging (beta) in Messages is available with supported carriers and will roll out over time.” The build is part of the broader 26.5 push that Apple is testing across iPad, Mac, watchOS and other platforms.
How it will look and where to enable it
When encrypted RCS is active, iPhone users will see an indicator in Messages that mirrors what Google Messages shows today. Conversations with Android phones will display a lock marker and the chat header will reflect RCS encryption (for example, Text Message · RCS | [lock icon] Encrypted). Android users running the latest Google Messages will see the same visual cue they already see for encrypted RCS chats with other Android phones.
On iPhone the toggle lives in Settings > Messages > RCS Messaging. Apple notes the End-to-End Encryption (Beta) switch is on by default, but you can confirm or change it there. The feature depends on supported carriers and will be rolled out gradually, so not every user will see it the instant iOS 26.5 ships.
Apple began testing RCS encryption in February as part of earlier 26.x betas. If you’ve been tracking the previews, you might recall details posted when the developer seed arrived; Apple has iterated quietly since then as it rounds up carrier support and final polish. For background on those developer-stage changes you can read the earlier notes about the iOS 26.5 developer beta and the public beta that followed.
Why this actually matters
RCS (Rich Communication Services) has been pitched for years as the successor to SMS — richer media, typing indicators, read receipts and, crucially, the possibility of encrypted cross-platform texting. The GSM Association updated the RCS Universal Profile to include end-to-end encryption last year; Apple’s move now plugs iPhone into that inter‑operable standard in a way it hadn’t before.
Practically speaking, this is a privacy win for people who split their social circles across iPhone and Android. For a long time, cross‑platform messaging forced a compromise: iMessage stays closed and private within Apple's garden, while SMS (and some early RCS implementations) lacked modern encryption. With RCS E2EE between the two ecosystems, those conversations no longer have to choose between features and privacy.
That said, the experience won’t be identical to an all‑iMessage thread. Encryption depends on carrier support and the Android recipient running an up‑to‑date Google Messages app, and Apple labels the capability as beta while it monitors the rollout. Expect a staggered availability rather than an overnight flip.
Apple’s 26.5 candidate also bundles other small additions — from Maps tweaks like Suggested Places to aesthetic touches — but encrypted RCS is the kind of cross‑platform change that could quietly improve everyday privacy for millions of users. If you're enrolled in Apple’s beta testing programs or watching for the public release, keep an eye on Settings > Messages > RCS Messaging and the lock icon in conversations; those are the clearest signs the handoff between systems has finally tightened up.
(If you want the nitty-gritty about earlier 26.5 notes, Apple’s developer beta coverage and the public beta writeup track the rollout closely.)
