Wi-Fi calling on Verizon iPhone 5s running iOS 12.4
Does anyone have work around to get wi-fi calling on 5s with Verizon carrier and iOS 12.4 or later? Wi-fi calling is not showing up at all, neither under settings>cellular nor settings>phone. Also having problem maintaining wi-fi connection even with phone right next to router. Having none of these problems with iPhone 6s on same wi-fi network and with same carrier, Verizon, and iOS.
