========================================
I'm using Mint Mobile (T-Mobile MVNO), and Wi-fi calling doesn't work. The option doesn't even present itself in the menu. I find it very hard to believe that a product that markets itself as fully compatible with T-Mobile and its MVNO's doesn't support this basic feature. I was wondering if anyone has found a way to make this work, or is this just an early adoption bug?

T-Mobile "calling over wifi" works in my country, so it should only be a setting change for Asus.

The other provider it does not in my country is KPN.
Entering the code #*#3642623344#*# does bring up "calling over wifi" for the KPN, but it doesn't work

I literally cannot believe you have a mobile provider that is literally owned by the actor that plays deadpool.
