Question: This notification keeps appearing on my Mac running Mac OS X 10.13.6 (17G65):

[![Notification that Wi-Fi calling is available](https://i.stack.imgur.com/G5uYI.png)](https://i.stack.imgur.com/G5uYI.png)

> 
> **Wi-Fi Calling**  
> 
>  You can use your phone number to make and receive calls directly on this Mac using Wi-Fi.
> 
> 
> 

I have:

1. Clicked "Not Now"
2. Clicked "Turn On"
3. On my Mac: Turned off *all* notifications for FaceTime
4. On my Mac: Logged out of FaceTime
5. On my iPhone: Went to "Settings" » "Phone" » "Wi-Fi Calling" and turned ***off*** "Add Wi-Fi Calling for Other Devices"
6. On my iPhone: Went to "Settings" » "Phone" » "Wi-Fi Calling" and turned ***off*** "Calls on Other Devices"

Still, after all of that, **the notification keeps coming back every few minutes**.

Any ideas how to kill this thing?

I tried Google but all of the results were about turning this feature *on*, not *off*.

Answer: 
My Mac kept nagging after configuring a new iPhone. Despite turning WiFi calling on on the Mac, and rebooting, the nags kept re-appearing. 

What finally caused a stop was updating my E911 emergency contact on the phone. No more Mac nags!
I recently upgraded to the iPhone 12mini (from iPhone 6s) and was receiving this issue. After some poking around, here's how I was able to solve it:

* Sign out of iMessage / FaceTime on your old iPhone.
	+ *Or more drastic, erase all content and settings from your old iPhone.*
* Sign out then sign back in to iMessage and FaceTime on your new iPhone.
* Authenticate / allow wifi calling from new iPhone.
