Installing iOS 27, which Apple released on September 14, doesn’t automatically switch on the redesigned Siri everyone’s been waiting for. To actually try the new Siri AI, eligible users still need to join a waitlist first, a detail that’s tripping up plenty of people who assumed the update alone would do it.
Getting on the list means going to Settings, tapping Siri, and selecting Try Siri AI (Beta), turning Siri on first if it’s currently off. From there it’s a short setup, picking a voice, completing voice enrollment, and reviewing privacy settings, before you’re actually added to the queue. Per Apple support page, wait times vary, and Siri AI downloads automatically once your turn comes up. Oddly, even people who had Siri AI running during the iOS 27 beta reportedly have to rejoin the waitlist again now that the software’s gone public.
Hardware eligibility is narrower than iOS 27 itself. The OS runs on a fairly wide range of iPhones, but Siri AI is limited to Apple Intelligence-capable models: iPhone 15 Pro, iPhone 15 Pro Max, the iPhone 16 lineup and anything newer, plus iPhone Air. That leaves plenty of iOS 27 users, on older hardware, able to install the update but not able to access the headline feature, even on devices launching this season like the iPhone 18 Pro.
There’s a language and regional layer on top of that. Device language and Siri’s language both need to match a currently supported language, and at launch that means English only, with French, Japanese, Korean, Portuguese, and Spanish expected to follow later. Regional restrictions apply too: Siri AI isn’t available on iPhone or iPad in the EU at launch, and China faces its own limitations, so a compatible phone alone doesn’t guarantee access. On top of that, Apple Intelligence’s models and resources can take up anywhere from roughly 8GB to 14GB of storage depending on the device, on top of whatever downloads once your waitlist spot opens up.
What you actually get once it’s running is a meaningfully different assistant. Siri AI can pull personal context from Messages, Mail, and Photos, stay aware of whatever’s currently on screen, hold more natural back-and-forth conversations instead of requiring rigid phrasing, carry out actions across multiple apps in one request, answer general knowledge questions, and tap into an expanded Visual Intelligence system. Apple also rolled out a dedicated Siri app for revisiting past conversations across devices.
The waitlist approach mirrors how Apple handled the original Apple Intelligence rollout with iOS 18, gradually expanding access rather than flipping it on for everyone at once. Apple hasn’t given a maximum wait time, so there’s no real way to predict how long any individual user will be stuck watching for that notification. Siri AI itself was first announced back on June 8, 2026, alongside the rest of this year’s Apple Intelligence push, and even now, with iOS 27 fully public, Apple is still treating it as a beta rather than a finished feature.
