WiFi calling is an add on Apple feature licensed to the cell provider for calls and texts to be sent and received when the phone is not connected to the Consumer Cellular cell network. Not all cell providers license the feature and some restrict the usage. WiFi calling is required for IMS.
I am not certain how Android licenses WiFi calling but my Pixel and prior Samsung phones are enabled for WiFi calling.
