It does note appear that Android has that functionality. On my Pixel 4 (and 3A), I cannot use the data connection on one SIM to put through calls from the other SIM, even when I have selected wifi calling preferred.
Anyone able to do this on Android?
BTW, here is a thread on Reddit that starts with a screen shot of what it looks like on a Iphone:

I'm on T-Mobile which does not charge for WiFi calls to/from the US while roaming internationally. I've been experimenting with this in the US for the past month or so, and it is quite reliable, with good quality calling also. I've used T-Mobile, Verizon, and 3 UK service for the data service and all perform equally well.
I have no experience with Android, but I understand the function is similar, isn't it?
