Siri AI Not Working on iOS 27? Fix Apple Intelligence & Siri

Check If Your iPhone Supports AI Siri

If Siri AI is not working on iOS 27, first check whether your iPhone supports Apple Intelligence. Compatible models now include iPhone 18 models, iPhone 17 models, iPhone Air, iPhone 16 models, and iPhone 15 Pro and iPhone 15 Pro Max. Older iPhone models cannot access Siri AI features powered by Apple Intelligence, even after updating to iOS 27. Language and regional availability may also affect which features are available.

If you have a compatible iPhone but Siri AI is still not working, make sure you're running the latest version of iOS 27 and that Apple Intelligence is enabled. Features may also take some time to become available while required models and system components are being downloaded or set up.

Latest Update:

Siri AI is already available as an English beta with iOS 27, which launched on September 14, 2026. Apple has confirmed that French, Japanese, Korean, Portuguese, and Spanish support is coming in October, but has not given an exact date. Apple released the first iOS 27.2 developer beta on September 16, although the public release date has not been announced.

1. Make Sure Apple Intelligence Is Enabled

Even on a compatible iPhone, Apple Intelligence must be turned on manually; it isn't always active by default after an update.

• Open Settings and tap Apple Intelligence & Siri.
• Toggle Apple Intelligence on if it isn't already.
• Restart your iPhone once the toggle is enabled, then reopen Siri to test it.

This single step resolves a surprising number of "Siri AI not working" reports, especially for anyone who updated to iOS 27 without going through the full setup prompts.

2. Check Siri Language and Region Settings

Siri AI's smarter features are currently tied to specific supported languages, and a mismatched language or region setting can quietly disable them.

• Go to Settings > Apple Intelligence & Siri > Language.
• Confirm your Siri language is set to a language currently supported by Apple Intelligence and Siri.
• Check Settings > General > Language & Region to make sure your region matches a supported market.

If your region or language falls outside Apple's current support list, Siri AI features may stay greyed out even though the classic Siri assistant keeps working normally.

3. Make Sure Apple Intelligence Has Finished Downloading

Apple Intelligence relies on an on-device AI model that has to download and install after you turn the feature on and it's easy to miss that this hasn't finished.

• Head to Settings > Apple Intelligence & Siri and look for a progress indicator or "Finishing Setup" message.
• Connect to Wi-Fi and keep your iPhone charging, since the download can be several gigabytes and may pause on cellular data or low battery.
• Give it time depending on your connection, the initial setup can take anywhere from a few minutes to a few hours.

Trying to use Siri AI before this download completes is one of the most common reasons people report that Apple Intelligence not working or Siri responding like the old assistant.

4. Turn Siri Off and On Again

A basic reset often clears out temporary glitches that block Siri AI from responding correctly.

• In Settings > Apple Intelligence & Siri, turn off both Listen for "Siri" and Type to Siri.
• Wait about 15--20 seconds.
• Turn both settings back on and complete the brief voice re-training prompt if it appears.

This forces the system to refresh Siri's voice recognition profile and reconnect to Apple's servers, which frequently fixes cases where Siri hears you but doesn't respond, or responds with outdated, non-AI answers.

Note:

Some users have also reported Siri AI suddenly returning an “Uh oh, something went wrong” error for both on-device requests and tasks handled through Private Cloud Compute. One Reddit user also wondered whether a daily usage limit was involved, even while using a 5G cellular connection.

Siri Says “I'm Having Trouble With the Connection”

If Siri shows “I'm having trouble with the connection” or asks you to try again later after updating to iOS 27, the problem may be related to your network, VPN, or a temporary Siri service issue. Some iOS 27 users have reported seeing this message repeatedly, especially when asking Siri to look up information online.

• Switch between Wi-Fi and cellular data to see whether the connection improves.
• Temporarily disable any VPN or network-filtering app, then test Siri again.
• Restart your iPhone and try the same Siri request once more.
• If Siri suddenly stops working for multiple requests while your internet connection is otherwise normal, wait and try again later, as the issue may be temporary on Apple's side.

If Siri works normally for basic commands but fails mainly when searching the web or completing more advanced requests, check your connection before changing other Siri settings.

If none of the settings-based fixes work and Siri AI is still unresponsive, frozen, or your iPhone is behaving oddly after the iOS 27 update, the issue may be a deeper system glitch rather than a simple toggle.

FAQs About Siri AI Not Working on iOS 27

Why is my AI Siri not working?

The most common causes are an incompatible iPhone model, Apple Intelligence not being enabled, an unfinished on-device model download, or a language/region setting that doesn't yet support Siri AI. Working through Settings > Apple Intelligence & Siri usually identifies which of these applies to you.

Does iOS 27 support Apple Intelligence?

Yes. iOS 27 is built around an expanded version of Apple Intelligence, but it only runs on iPhone 15 Pro, iPhone 15 Pro Max, and iPhone 16 or later. Older iPhones can install iOS 27 itself but won't gain access to Siri AI or other Apple Intelligence features.

Why Does Siri Say “I'm Having Trouble With the Connection” on iOS 27?

This message can appear when Siri cannot complete a request that requires an internet connection. Check your Wi-Fi or cellular connection, temporarily disable any VPN, and restart your iPhone. If Siri suddenly fails for many requests while other apps are online, the issue may also be temporary on Apple's side. Some iOS 27 users have reported the same connection message repeatedly after updating.

Conclusion

If Siri AI is not working on iOS 27, start by checking Apple Intelligence compatibility, settings, language and region, and whether the required features have finished setting up. For connection errors, slow responses, or Siri not responding, also check your network, disable any VPN temporarily, and restart your iPhone. If these steps don't resolve the problem and Siri issues continue across the system, Tenorshare ReiBoot can help troubleshoot certain iOS system-level issues with its Standard Repair mode while aiming to keep your personal data intact.
