Apple Watch 3 cannot unlock iphone

Hello, JMPoison.

Thank you for posting in Apple Support Communities. We understand that you’re no longer able to use your Apple Watch to unlock your iPhone when you’re wearing a mask after up dating the software on both devices. 

Let’s check the requirements to see if you have everything set correctly.

- You need to be wearing a mask that covers your mouth and nose.

- Bluetooth and Wi-Fi should be enabled on both devices.

- Your Apple Watch should have a passcode and Wrist Detection enabled.

Warmest Regards.

Justin,

This is such a great feature! We can understand why you're looking into a resolution. Since the connection requires Bluetooth and Wi-Fi, is it possible you may have some wireless interference? Do you have any other Bluetooth devices connected? You might try temporarily disconnecting those and test in an area without any potential interference.

If you're still not able to unlock, try powering off your Apple Watch and then your iPhone for a few minutes. When you're ready to turn them on again, make sure you power the iPhone first.

If you're still not able to unlock with your Apple Watch, you may need to contact Apple Support for more advanced troubleshooting.

Good luck!

Justin,

You're very welcome. We're glad it was just a minor oversight that resolved the issue for you. Thank you for replying and letting us know.

Cheers.
