Yeah, it sucks because AT&T is the one blocking that feature from unlocked phones. So far I have only seen the pixel 3 as an unlocked phone having WiFi calling on AT&T. Guess google struck up a deal with them.
It might be possible Samsung may have struck a deal too, but so far none have worked and I would wait until it’s confirmed to have it or not before getting the unlocked model.
Thanks, not surprised that AT&T would pull that. I am sticking with Verizon. It’s interesting none-the-less.
