This shouldn't be surprising, AT&T WiFi calling works everywhere but here:
"Wi-Fi Calling is restricted in the following countries: China, Saudi Arabia, India, Turkey, Israel, United Arab Emirates, Vietnam, Pakistan, Cuba, Iran, North Korea, Sudan, and Syria."

The list changes all the time and is subject to local restrictions. Best to check the link above just before you travel to avoid unpleasant surprises. Anecdotal stories here on FT don't really help that much.

The list is not surprising, it is mostly countries with US sanctions, or countries where VoIP is heavily banned (because of "security", censorship, or telecom monopoly protection)
Really the only one which I am surprised to see is Israel.

Not really useful to those of us who already use FaceTime to bypass high telecom rates when traveling overseas. Ironically AT&T had a wifi app that it was pushing a couple of years ago, but later decided to cease support and ultimately deleted it.

It's important to note that at least on AT&T it doesn't matter if a phone is natively able to do wifi calling. AT&T has to approve the device, and so far at least they only approve iPhones and devices sold by AT&T.
AT&T is wildly customer-unfriendly, and sadly no OEM who cares has the power to force their hand on Android devices.

Why don't you enlighten us who are so ignorant as to how this differs from Facetime, Skype and any number of other apps? And why we should care?

I use it to dial into US conference calls when I'm overseas. I find it much more reliable and clearer than Google Hangouts or Skype.

Here is what I came up with:
1) Video. FaceTime / Skype have video and audio. WiFi calling has audio only. All three have audio only options.
2) FaceTime - both people must have a Apple device, at least as far as I know.
3) Skype - both people once needed a smart phone or tablet or computer, but not anymore if you use a premium (not free) version of Skype. Then the other person can be using a landline and have no idea you placed the all through skype.
4) With WiFi calling, the other person sees your normal phone number and they can use a regular phone, land line, etc. But Skype can do this now also.
5) Calls to 911 can give false locations through wifi calls.
From my experience, call quality is highly depended on a good internet connection for any of these options.
I see no clear winner between the three, but would add their is something special / memorable about a video call from a person at a remote, far off destination.

WiFi calling works exactly the same as cellular calling on your phone. The only difference is that your call is connected via WiFi instead of your carrier's cellular network. There is no difference how the calls are made and received. There is no need to install or use any special apps. My phone switches automatically and seamlessly midcall from cellular to WiFi when I am in a weak cellular reception area.

In practice I - and many others - have disconnected the "wifi" option for mobile calls due to the well known battery drain, as summarized by T-Mobile:
1.On LTE radio only battery drain is about 0.3% to 0.7% per hour with no active use of the phone.
2.On turning on WiFi battery drain goes to 10% to 11% per hour with no active use of the phone.
3.On turning on Airplane mode to shut down LTE, followed by turning on WiFi, usage is still 10% to 11% per hour.
Really there is no need to enable WiFi calling in the USA if (1) You have an unlimited minutes plan (vast majority of us do) and (2) You are rarely outside of an area with sufficient cell tower coverage. Even so you could still use one of the apps listed above just as easily from a location that has wifi.2.On turning on WiFi battery drain goes to 10% to 11% per hour with no active use of the phone.

As I noted above, the bigger draw is when traveling overseas so as to avoid heinous roaming charges on the regular mobile networks. But again, the apps serve the same purpose. The only difference with enabling the wifi calling is that you phone can automatically toggle between cell towers and wifi, but then you risk high fees on the mobile network (or limit yourself to the same wifi locations that you could access through the apps).

I personally find Skype rather cumbersome to use and limit my use of the app to international calling (calling from the US to international destinations or calling from one foreign country to another).
