I set my iPhone 6 to allow WiFi calling and WiFi appears in the status bar at the top of the iPhone screen.
I am using a Prepaid T-Mobile plan. My understanding is that WiFi calls are not charged against my minutes but mine are.
Does anyone know why I am being charged for calls over WiFi? Thanks.
You have to turn off the cellular network and connect exclusively thru Wi-Fi. Someone stated to go airplane mode and turn on Wi-Fi manually.
WiFi calling does use minutes
