I checked at mine, it's active server. Unfortunately, public mobile doesn't offer wifi calling. VOLTE is avialabe. this is the one holding me on another carrier.
I prefer freedom for one reason, because it does Wi-Fi calling ( Vowifi) . You can use as long as Wi-Fi is connected even out of country . but public mobile doesn’t have an option for Wi-Fi calling . That’s the only thing which puts me in another car...
