Recently acquire AT&T A10e. The Wi-Fi calling switch is missing, as in not there, absent. I know where it’s supposed to be, but it’s not. I spent considerable time on the phone with AT&T, they assured me that Wi-Fi calling is enabled for my account but were unable to resolve the issue. I’ve tried the various remove SIM, reinstall and reboot solutions found online to no avail. I’ve performed a hard reset. Nothing has brought the switch back. Please help!
