Apple has released iOS 27 with Siri AI as its headline feature, a comprehensive overhaul built with Google partnership that enables conversational input and access to emails, messages, and on-device content. However, users must manually enable Siri AI and join a waitlist. To sign up, update to iOS 27 or iPadOS 27, then go to Settings > Siri > Try Siri AI (Beta), ensuring language is set to English (United States) and region to United States.

Support for French, Spanish, Portuguese, Japanese, and Korean arrives October 2026. Device compatibility is limited: iPhone 15 Pro series or newer for iPhone, and seventh-gen iPad mini (A17 Pro) or M1 iPad or later for iPad. Users in China or the European Union cannot join due to EU Digital Markets Act (DMA) disputes; Apple argues opening Private Cloud Compute to rivals threatens privacy.

Advanced features like Expressive Voices and Advanced Dictation require iPhone 17 Pro or newer. The waitlist manages cloud infrastructure demand, preventing slowdowns as millions enable the feature simultaneously. Apple balances computational load by gating access rather than enabling by default.
