Apple will roll out the first public beta of iOS 27 in July, likely later this month. Historically, public betas for iOS 16‑26 launched between July 11 and July 24, so the schedule matches past patterns. Users can install the build for free once it appears in Settings → General → Software Update → Beta Updates.

To prepare, sign up at beta.apple.com, then enable beta updates on a compatible device. iOS 27 supports iPhone 11 and newer, but the new Siri AI, powered by Apple Intelligence, only runs on iPhone 15 Pro and later and currently sits on a waitlist. Backing up data and using a secondary phone are strongly advised because betas often introduce glitches.

Installing the public beta is straightforward, but expect occasional performance hits and app incompatibilities, especially with CarPlay. Early adopters can also jump to the developer beta, which is already available. The rollout signals Apple’s push to refine AI-driven features before a full iOS 27 release later this year.

For those eager to test Siri’s new capabilities, open Settings → Siri once iOS 27 is installed and join the waitlist; access may take weeks. Meanwhile, the OS brings Liquid Glass visual tweaks, faster app launch times, and expanded child‑safety controls. The beta gives developers a chance to fine‑tune these changes ahead of the final launch.
