Same, in exactly the same situation, anyone got it working with a unlocked Pixel 2 XL and a BT sim ?
I'd love to know this too. I really want a Google Pixel 3 but do not want to buy it without BT Wi-fi calling.
Watched this thread from the start, 2 iPhones and an S8+ all happily working on wi-fi calling, Came home today and my Pixel 2XL working.....finally. On Nov updates but didn't notice anything immediatley after so not sure if it had anything to do with it.
Happy days, Just need VoLTE now.
My spare phone a cheapo Nokia 2.1 bought from Carphonewarehouse running a BT sim works lovely on wifi calling even though when I login to my account on BT website say it say's I don't get it😀 nor 4G too.
