Setting up WiFi Calling service on Honor 8X

[Blecheron]

I recently purchased Huawei Honor 8X on Amazon
The exact model is JSN-L22 (Global)
What does 'Global' mean?
I miss many settings and features on this model which do exist on other model (like the European one).
For example I can't find on this device how to enable/activate the WiFi Calling feature
Anyone can help?
My carrier is Cricket which is sub-carrier of AT&T (it means that I use the AT&T towers)

In many cases, some features (like wifi calling) end up being enabled only when you purchase the phone from the carrier.

After checking the phone to see if it supports the feature, and checking your phone plan to see if the feature is included, you may need to check with your carrier to see if the feature is restricted by sales policies.

Global means "not in North America" - it may be missing some 4G bands that AT&T uses (like 4, 5 and 7). (There's also an Asian version and a separate Chinese version. See https://www.gsmarena.com/honor_8x-9313.php)

And non-AT&T phones (those branded Cricket are AT&T) usually can't use AT&T WiFi calling.

The carrier (Cricket through AT&T (it's low-end, cheaper brand)) supports the feature.
The plan also supports the feature.
The phone doesn't have the feature in settings so I can't tell if it supports it or not, this is the reason for my post.
The question is if I can enable it myself on this device.
The device was not purchased from the carrier. It was purchased unlocked on amazon.com

If it misses some 4G bands that AT&T uses than how come I manage to still use it uninterrupted with Cricket SIM?

This is strange. This site suggests no 4G capability https://www.frequencycheck.com/comp...lx2-jsn-l22-64gb-huawei-johnson/united-states

Are you getting 4G?

 

[Blecheron]

Yes, I am, through Cricket (AT&T's towers)

Just found a list of supported devices on Cricket. It's not good news
