Does the P20 Pro work in the US on T-Mobile with VoLTE?

[webadass]

I am from the US and currently in Singapore, where I am considering picking up a P20 pro.
CLT-L29C: Dual SIM Card
LTE TDD / LTE FDD / WCDMA / EDGE / GPRS

Will this work with AT&T or T-mobile in the US? Will it have wifi calling? (I live in an area with subpar reception and use wifi calling extensively)

Thanks.

Yes it does work. And the fact that you can mimic one number or multiple numbers as many times as you'd like on multiple devices is pretty cool.

So if I use DIGITS while Wi-Fi is active, it will make the call in Wi-Fi??

I guess when not needing Wi-Fi calling, I can just disable the app.
