Can a iPhonexr make Wi-Fi calling ?

Yes Wi-Fi Calling can be activated on an iPhone XR. The thing to note here is that that feature has to be available from your carrier. Call your carrier to confirm whether Wi-Fi Calling is available with your plan (If you are not sure).

To activate Wi-Fi Calling, open Settings ➔ Phone ➔ Wi-Fi Calling : Here, set Wi-Fi Calling on This Phone to ON.

Yes, if your carrier supports that service and you included it in your traffic plan.

Contact your carrier and ask them.
