My iPhoneXR won’t let me pair with my Apple Watch Series 3 I’ve tried manually and it didn’t display the code i don’t know what to do i need help

Hi TBurns95,

Thanks for posting in Apple Support Communities.

There are a few steps that can be taken if your Apple Watch isn't pairing. Make sure that your iPhone is updated, has been restarted, and has Bluetooth enabled and connected to a stable Wi-Fi network. Both devices need to be within 30 feet of each other. These steps are from the resource below, and it appears to you may have already viewed it before posting. Make sure you've covered all of the steps from that link, and let us know if the issue persists.
