But I'm sure you're intelligent enough to realize that the users on HoFo are far from an accurate representation of the general population of cellular customers. The average customer isn't paying for service on multiple carriers. Pointing out that a handful of phone junkies on a tech website who pay for service with several carriers isn't a strong case for argument.
I haven't seen anyone bragging here bragging about using WiFi calling to make up for T-Mobile's shortcomings on the road or in rural areas. It's just something useful to have in buildings where cellular signals can have trouble penetrating. No matter how much you downplay it, it's a nice feature to have rather than not. I'd certainly prefer to use Wi-Fi calling over the $100 cell boosters that AT&T/VZW sell and I'm sure their customers would prefer that as well. If their coverage was so strong in all buildings then they wouldn't even offer them.
There is no setup to the cell boosters, i dont have to give out my wifi password, and anybody in my house can use it. most public wifi stinks, cant even facetime from it...like Panera for example. but that is an entire other conversation.
