Hello tess_nuguid,

Thanks for posting in the Apple Support Communities.

We understand you're looking for assistance with pairing your iPhone XR and Apple Watch, so let's check into this.

If you're unsure of the watchOS version, determining this may be helpful as the iOS version may need to be updated. Let's check out the following steps to see if they help with clearing up what's occurring. If not, take a look at this resource for additional steps to try: If you can't pair an Apple Watch with your iPhone - Apple Support

If the pairing process stalls

If it seems like the pairing process has stalled — for example, the pairing animation remains on the screen for several minutes — resetting your Apple Watch might help:

1. Press and hold the Digital Crown while your Apple Watch is in pairing mode.

2. Tap Reset when it appears on your watch.

3. After your watch resets, you can pair again.

If you see you need to update your iPhone, be sure to complete a backup of your information prior to completing the installation. For help with backing up or updating, check out this resource: Update your iPhone or iPad - Apple Support

We hope this is able to help.

Have a great day!
