Apple Watch 8 doesn’t show incoming calls

Hey Colin.Harrison,

You should be able to answer calls on your Apple Watch. For more information, review this article:Answer phone calls on Apple Watch - Apple Support

Since updates include fixes, making sure both devices are up-to-date.

• Update your iPhone or iPad
• Update your Apple Watch

If you continue to experience the issue, power off both the iPhone and the Apple Watch. Afterwards, power them both back on.

If the steps above do not resolve the issue, unpair the Apple Watch and then pair it again. When you select to unpair Apple Watch, a backup is automatically created and can be restored afterwards.

To unpair the Apple Watch and set up the Apple Watch again, follow the steps below, or access the steps in this article: Unpair and erase your Apple Watch.

"If you're using your Apple Watch with a transit card in the Wallet app, remove your transit card from your Apple Watch before you unpair."

1. "Keep your Apple Watch and iPhone close together as you unpair them.
2. Open the Apple Watch app on your iPhone.
3. Go to the My Watch tab and tap All Watches.
4. Tap the info button  next to the watch that you want to unpair. 
5. Tap Unpair Apple Watch.
6. For GPS + Cellular models, choose to keep or remove your cellular plan. 

• If you want to pair your Apple Watch and iPhone again, keep your plan. 
• If you don't want to pair your Apple Watch and iPhone again, remove your plan. If you aren't going to pair with a different watch or iPhone, you might need to contact your carrier to cancel your cellular subscription. 

7 Tap again to confirm. You might need to enter your Apple ID password to disable Activation Lock. Before erasing all content and settings on your Apple Watch, your iPhone creates a new backup of your Apple Watch. You can use the backup to restore a new Apple Watch. After your Apple Watch unpairs, you'll see the Start Pairing message.

8 Set up your Apple Watch again."

Hope this helps. Take care.
