> that let Pixel users enable VoLTE anywhere

It did a great deal more than that. It also allowed the toggling of VoNR, which apparently affected the fallback behavior of some people's services. (Ie. It would fall back to LTE and not roam back to 5G data unless nudged manually)

However for me, it would enable backup calls over a secondary sim card's data, which would allow text and calls overseas without the usual extortionate charges. Oddly enough, I believe that toggle is enabled for my carrier... but only on iOS.

> that toggle is enabled for my carrier... but only on iOS

WiFi calling with SIM1 number via SIM2 data has always worked on iOS, so I was surprised when it didn't work on Pixel.

This does work on Pixel's, but Google allowed carriers to block it, which at least one major US carrier does.

This is the “Backup calling” toggle in Pixel IMS, and carriers are fond of blocking that function.

(TIL: Vo“WiFi” over wired Ethernet over USB doesn’t work on AOSP or Pixel and never did, for no apparent reason except noöne caring to make it work.)

The part that does not work on iOS is putting SIM2 into airplane mode so that it can do VoWiFi without connecting to the network. That would reduce power consumption and avoid utterly obnoxious behavior on the part of some carriers (cough, Visible).
