Why does Huawei p20 pro not work with tmobile wifi calling?

[Android Central Question]

I don't have a Huawei p20 pro but looking into it. I like the wifi calling feature with tmobile because when I travel abroad wifi calling with my us phone number is free. Any way to get this feature installed on Huawei p20 pro or do I have to wait for oneplus to make a splash with tmobile?
