Siri not working on Apple Watch? Here’s how I fixed it in watchOS 27

Apple Watch has become much more than a device for tracking fitness and checking notifications. With Siri, you can set timers, send messages, check the weather, start workouts, and perform several everyday tasks without reaching for your iPhone.

Things have become even more interesting with watchOS 27, which introduces the new Siri AI experience powered by Apple Intelligence. Siri now offers a more conversational interface, understands personal context, answers broader questions, and can take action within apps.

However, the new experience isn’t perfect. For instance, some Apple Watch users have reported network errors and slow responses. If Siri isn’t responding, keeps showing an error, or asks you to try again, don’t worry. I’ve put together these troubleshooting solutions to help you identify and fix the problem.

Before you start: Check Siri AI compatibility

Not every Apple Watch supports the new Siri AI experience. According to Apple, Siri AI (Beta) requires:

• Apple Watch Series 9 or later.
• Apple Watch Ultra 2 or later.
• Apple Watch SE 3.
• A paired Apple Intelligence-compatible iPhone (iPhone 15 Pro, iPhone 15 Pro Max, or iPhone 16 models or later).
• Compatible Siri and device language settings.
• Availability in a supported region.

Siri AI is available in beta, and availability can vary by language and region. If you have an older Apple Watch, you can still use classic Siri, provided your device supports the feature.

12 ways to fix Siri not working on your Apple Watch

I’ve put together easy fixes that I’d try to get Siri back on track, including solutions for the new Siri AI issues in watchOS 27.

1. Check the internet connection on your Apple Watch

The first thing I will do is make sure the internet connection is working properly. Siri needs an active internet connection to process requests, and the new Siri AI experience also relies on cloud-based processing for many of its capabilities.

If your Apple Watch isn’t connected to Wi-Fi or a cellular network, you might see an error such as “Sorry, something went wrong,” or Siri might take unusually long to respond.

On Apple Watch with cellular:

1. Open Control Center on your Apple Watch.
2. Check the cellular connection indicator. It should be green.
3. Make sure your cellular plan is active and that you have network coverage.
4. If the cellular connection is weak, move to an area with better cellular reception.

On Apple Watch with Wi-Fi:

• Go to Control Center and check that Wi-Fi is turned on. You will see an iPhone icon at the top if your watch is connected to your iPhone.
• Otherwise, open the Settings app on your Apple Watch and tap Wi-Fi. Ensure your watch is connected to a Wi-Fi network.
• If necessary, connect to a reliable network.

On your paired iPhone:

1. Open Control Center on your iPhone.
2. Check whether Wi-Fi or Cellular and Bluetooth are enabled so your paired Apple Watch can access the internet.
3. Open Safari and visit a website to confirm that your internet connection is working.
   

My suggestion: If classic Siri works but Siri AI keeps displaying network errors, try switching between Wi-Fi and cellular data. You can also temporarily disable a VPN to see whether it is interfering with Siri’s connection to Apple’s cloud services.

2. Turn Airplane Mode on and off

If Siri is not responding, try to refresh the network connection by switching to Airplane Mode. It is a very effective troubleshooting tool that helped me cope with temporary connectivity issues.

On Apple Watch:

1. Press the Side Button to open Control Center.
2. Find the Airplane Mode icon.
3. Tap it to turn Airplane Mode on.
4. Wait for a few seconds.
5. Tap the icon again to turn it off.
   

Alternatively, open Settings → Airplane Mode and toggle it on and off.

On paired iPhone:

1. Open Control Center.
2. Tap Airplane Mode to enable it.
3. Wait for a few seconds.
4. Tap it again to disable it.
   
   

Once your devices reconnect to the internet, try invoking Siri again.

3. Make sure Siri is enabled on your Apple Watch and iPhone

Sometimes the problem isn’t your internet connection. Siri might simply be disabled on one of your devices.

With the updated Siri interface in watchOS 27, you can also switch between Siri AI and the previous Siri experience on supported devices.

To enable Siri on Apple Watch:

1. Open the Settings app.
2. Scroll down and tap Siri.
3. Check whether Siri is enabled. To use Siri AI, tap “Try the new Siri (Beta).”
4. Make sure your preferred activation methods are turned on.
   

You can activate Siri using any of these methods:

• Listen for “Siri” or “Hey Siri”: Say the activation phrase followed by your request.
• Raise to Speak: Raise your wrist and speak directly to your Apple Watch.
• Press Digital Crown: Press and hold the Digital Crown until Siri appears, then speak.

If one activation method isn’t working, I always try the other one to determine whether the issue is voice detection or Siri itself.

On iPhone:

1. Open the Settings app.
2. Tap Siri or Apple Intelligence & Siri, depending on your iOS version.
3. Select Requests and ensure Listen for “Hey Siri” or “Siri” is selected.
   

If Siri is already enabled, tap Off in the Requests menu and set it up again. This can help resolve temporary configuration issues.

4. Switch between Siri AI and Siri Classic

The new Siri AI experience offers more advanced capabilities, but it is still in beta. There are complaints about slower response times with Siri AI, inability to perform familiar tasks, and failure to find information that classic Siri could previously access.

If Siri AI is causing problems, switching back to Siri Classic is worth trying.

1. Go to Siri in the Settings app on your iPhone.
2. Tap Turn Off Siri at the bottom, then confirm it.
3. To use the previous version of Siri, tap Turn On Siri, then select Use Siri Classic. Tap Continue to proceed.
   

After switching, try familiar commands such as setting a timer, sending a message, or checking the weather. If these work normally, the problem might be related to Siri AI rather than your Apple Watch hardware.

5. Troubleshoot Siri AI network and response delays

If you have already checked your internet connection but Siri AI still takes too long to respond, the problem might not be with your Apple Watch.

Unlike some basic Siri requests, the new Siri AI experience relies on a combination of on-device processing and Apple’s Private Cloud Compute infrastructure. This means a slow connection or temporary cloud service issue can affect response times.

Here are a few things worth trying:

• Switch your network: Try connecting your iPhone and Apple Watch to another reliable Wi-Fi network.
• Temporarily disable your VPN: A VPN can sometimes interfere with the connection between your device and Apple’s cloud services.
• Unlock your iPhone: Some Siri AI requests involving personal context may fail when the paired iPhone is locked. Unlock your iPhone and repeat the request.
• Try a simpler command: Instead of asking a complicated question, start with something simple, such as setting a timer or checking the weather.

There is another limitation worth knowing. Siri AI doesn’t necessarily support every command that worked with classic Siri. For example, the new Siri AI doesn’t currently support queries about Health app data. I also got unexpected results from some familiar commands.

6. Increase Siri’s voice volume on Apple Watch

Sometimes Siri is working perfectly, but you might not hear its responses because the voice volume is too low.

I would check this setting before assuming that Siri has stopped responding.

On Apple Watch:

1. Open the Settings app and go to Siri.
2. Tap Siri Responses.
3. Ensure Always On is enabled.
4. Scroll down to find Voice Volume – Speaker.
5. Adjust the volume using the Digital Crown or the on-screen controls.
   

7. Restart your Apple Watch

Sometimes a temporary software glitch can lead to a malfunction in Siri’s response. Restarting your Apple Watch is a simple way to refresh its system processes.

1. Press and hold the Side Button and tap the Power button in Control Center.
2. Drag the Power Off slider.
3. Wait for your Apple Watch to shut down completely.
4. Press and hold the Side Button until the Apple logo appears.
   

If your Apple Watch is frozen and you cannot shut it down normally, you can try a force restart:

1. Press and hold the Digital Crown and Side Button simultaneously.
2. Keep holding both buttons until the Apple logo appears.
3. Release the buttons and wait for your watch to restart.

Once the watch restarts, invoke Siri and check whether it responds normally.

8. Check whether your Apple Watch microphone or speaker is blocked

If Siri can understand your commands but doesn’t respond properly, or if it cannot hear you at all, check the microphone and speaker.

Dust, debris, protective cases, and physical obstructions can interfere with these components.

Here’s what I recommend:

1. Remove any protective case or accessory that might be covering the microphone or speaker.
2. Check the microphone openings for visible dirt or debris and clean them properly.
3. Make sure your finger isn’t covering the microphone when speaking to Siri.
4. Test the microphone by recording a voice memo or using another app that requires microphone access.
5. Check whether the speaker produces sound when playing audio.

If your Apple Watch has recently been exposed to water, use Apple’s Water Lock feature to eject water from the speaker.

1. Open Control Center by pressing the Side Button.
2. Tap the Water Lock icon.
3. When you’re ready to eject water, press and hold the Digital Crown.
4. Your Apple Watch will play a series of sounds to clear water from the speaker.
   

Avoid inserting sharp objects, SIM ejector tools, or cotton swabs into the microphone or speaker openings. If you suspect physical damage or persistent blockage, contact Apple Support.

9. Use Type to Siri if voice commands aren’t working

Here’s another useful workaround that Apple specifically recommends when Siri isn’t responding to voice commands.

Instead of speaking, you can type your requests directly into Siri using the Type to Siri accessibility feature.

1. Open the Settings app on your Apple Watch.
2. Go to Accessibility.
3. Tap Siri.
4. Turn on Type to Siri.

You can also adjust Siri Pause Time in the same section. Choose Longer or Longest if Siri doesn’t give you enough time to finish speaking.

This feature is particularly useful if your microphone isn’t working properly or you prefer typing instead of speaking.

10. Download or update Siri’s voice

If Siri displays responses on your Apple Watch but doesn’t speak, the problem might be related to its voice package.

Apple notes that Siri’s voice may need to download before it can speak properly on supported Apple Watch models.

Here’s how to check it:

1. Open the Settings app on your Apple Watch.
2. Scroll down and tap Siri.
3. Find Siri Voice.
4. Select your preferred language and voice variety, if available.
5. Check whether the voice download is complete.
   

Keep your Apple Watch connected to Wi-Fi and place it on its charger to give the download enough time to finish.

11. Update your Apple Watch to the latest watchOS 27 version

If none of the above solutions work, check whether your Apple Watch is running the latest available watchOS version.

Apple regularly releases software updates that fix bugs, improve performance, and address issues with system features such as Siri. Follow the steps below to update your Apple Watch.

On Apple Watch:

1. Open the Settings app.
2. Tap General.
3. Select Software Update.
4. Wait while your watch checks for available updates.
5. If an update is available, tap Download and Install.
   

On iPhone:

1. Open the Apple Watch app.
2. Go to My Watch → General.
3. Tap Software Update.
4. Wait for your iPhone to check for updates.
5. Download and install the latest available version.
6. Don’t close the app until the update is completed.
   

Keep your Apple Watch connected to Wi-Fi, sufficiently charged, and on its charger during the update. Also, make sure your iPhone is running the latest iOS version.

I would also recommend enabling Automatic Updates so your watch receives future software improvements without requiring you to check manually.

12. Reset your Apple Watch

If Siri continues to malfunction after trying all the above solutions, resetting your Apple Watch can be your last resort.

However, I wouldn’t recommend doing this immediately. Resetting erases your watch’s content and settings, so make sure you have a recent backup and have tried the less disruptive solutions first.

Reset from Apple Watch:

1. Open the Settings app.
2. Tap General.
3. Scroll down and select Reset.
4. Tap Erase All Content and Settings.
5. Enter your passcode if prompted.
6. Confirm that you want to erase your Apple Watch.
   

Reset from iPhone:

1. Open the Apple Watch app on your iPhone.
2. Go to My Watch → General.
3. Scroll down and tap Reset.
4. Select Erase Apple Watch Content and Settings.
5. Follow the on-screen instructions.
   

After the reset, pair your Apple Watch with your iPhone again and test Siri before restoring any potentially problematic settings.

If Siri still doesn’t work after trying these solutions, you may have a hardware issue or a software problem that requires further investigation. I recommend contacting Apple Support or visiting an authorized Apple service provider. Explain whether Siri fails to recognize your voice, doesn’t produce audio, or displays an error when processing requests.

Bonus: Fix Siri AI conversation syncing issues

watchOS 27 introduces a dedicated Siri app where you can revisit previous conversations, continue discussions, and start new ones.

However, Apple has documented a watchOS 27 issue where Siri AI conversations might fail to sync with the paired Apple Watch, sometimes displaying a “No iCloud is configured” error.

If you encounter this problem, try refreshing your Apple Account connection.

1. Open the Settings app on your Apple Watch.
2. Tap Apple Account.
3. Allow your watch to refresh your account information.
4. Open the Siri app again.
5. Check whether your conversations are syncing.

Apple has also documented a related issue affecting some Apple Watch devices updated from earlier beta versions. In most cases, conversation syncing recovers automatically.

Signing off

Siri is one of the most convenient features of the Apple Watch, and the introduction of Siri AI in watchOS 27 makes the experience even more interesting. However, the new AI-powered assistant also brings its own challenges, including slower responses, network errors, and occasional issues with familiar commands.

If Siri isn’t working on your Apple Watch, I recommend starting with the basic troubleshooting steps, such as checking your internet connection, restarting your device, and verifying Siri settings. If you’re using Siri AI, switching back to Siri Classic can also help you determine whether the problem is specific to the new assistant.

I hope one of these solutions helps you get Siri working again. Let me know in the comments which fix worked for you.
