Apple has turned on end-to-end encryption for cross-platform RCS chats in iOS 26.5, giving iPhone and Android users a more private default for message threads that were already trying to catch up with iMessage. The catch is classic telecom fashion: the feature is arriving as a beta, and Apple says it will take months to reach everyone.
The iOS 26.5 update landed after six weeks of beta testing. Apple first brought RCS to iPhone in iOS 18.1, opening the door to richer messaging between iPhone and Android owners, and it started testing encrypted RCS in iOS 26.4. In iOS 26.5, the switch is enabled by default, though users can turn it off in Settings, then Messages, then RCS Messages, where Apple has added a new ”End-to-end encryption (beta)” toggle.
How iOS 26.5 RCS encryption works
Apple also updated the Messages interface so encrypted RCS conversations show a lock icon at the top of the thread, matching the look of iMessage chats, where end-to-end encryption has existed since 2011. Android users will see the same lock, which is a small but useful signal that the message is protected rather than merely ”secure” in the marketing sense.
The feature does not switch on everywhere at once. Apple says end-to-end encryption works only with supported carriers, and the company has published the list on a dedicated web page. Even if a carrier appears there, subscribers may still have to wait while the rollout reaches them over the next few months.
What changes for iPhone and Android users
- iOS version: iOS 26.5
- Rollout: after six weeks of beta testing
- Default setting: on, with an off switch in Messages
- Status: beta
This is Apple finally bringing its cross-platform messaging story a little closer to the standard users expect in 2026, even if the plumbing is still carrier-dependent. The bigger picture is less glamorous: encryption is only as good as the slowest operator, and that means the rollout will be uneven long after the headline fades.
Carrier support will decide how fast it spreads
That unevenness is the real story here. Apple can flip the software switch, but carriers still control when the feature reaches individual subscribers, so the promise of encrypted RCS will likely arrive in pockets rather than as a clean global launch. The good news is that the platform finally has the feature; the less exciting news is that telecoms remain telecoms.
