I'm on a US Factory unlocked S22 Ultra running on a Xfinity Mobile Sim and a T-Mobile eSIM

Is it possible to enable WIFI calling on both numbers ?

Seems its only enabled for T-Mobile I only see WI-FI Calling scrolling after T-Mobile scrolls like this Xfinity Mobile | T-Mobile WI-FI Calling

For some reason only T-Mobile is showing up as WIFI calling enabled ?

is there any other way to check if WIFI calling is enabled other then how it scrolls across the top ?

Would depend on Xfinity and if they have wifi calling? Just throwing that out there.

I was able to trouble shoot it and got Xfinity Mobile support to fix it

I have the exact same issue and phone configuration as you. Can you tell me what Xfinity Mobile had to do to fix this?

Sorry I can't remember exactly what they did. But the way I think I remember it what they had me first disable turn off the T-Mobile eSIM then they had me reset network settings and then take the Xfinity Sim card out reboot reinsert the sim and go into settings and try and reenable wifi calling for the Xfinity mobile sim only. For it to work it will have to ask you to enter your location and some personal info for 911 emergency services it does this just once after that wifi calling will be enabled then I went back and reenabled turned on the T-Mobile eSIM back on and it came right back on now with Wifi calling enabled now on both services. Been working ever since with no issues

I have wifi calling on both. Probably depends on your carrier.

So it is either this T Mobile phone software or possibly lock from my employer on the setting as the phone is controlled by them. So I tried your recalled fix without luck. The WiFi calling setting never appears for the SIM1 Xfinity Mobile. I see it only for T Mobile eSim2. I imagine the WiFi calling setting should have enable for each sim and not just ON setting. But I found an app called "Wifi calling" on Google Play that enables the VoWiFi setting and that worked. Now I have Wifi calling on Both SIM1 and eSIM T Mobile.

I have wifi calling on two networks and the question here if I can have wifi calling enabled while on not on wifi but on data for the primary sim.
Can the wifi calling on the secondary sim "see" the data on the primary sim in order to register for wifi calling?

It seems new Iphone did it. You can register any wifi calling using the second sim data
