I get your point but making calls is no longer the principal reason to own a smartphone. I have made no calls in the last two months and have received just one. But I have spent hours on Skype via WiFi, recorded tens of hours of video and taken hundreds of photographs, as well as read lots of books, sent and received money for goods that I have used the phone to list for sale online. Not to mention email and dozens of other applications.
Almost none of my use needed the cellular network.
