I've updated to iOS 8.4 and been trying out WiFi calling. I expected that calls made via WiFi wouldn't be tracked as Cellular usage on iPhone. However the minutes seem to match the phone calls that have been made. I'm referring to the time that's tracked from: Settings > Cellular > Call Time > Current Period
Could this possibly be because technically, and as far as Apple is concerned, the call communications are still handled/trafficked by the cellular carrier?
If I look at my Sprint account's "detailed usage" it separates out minutes into various buckets, including WiFi.
Conversely, from a simple, end-user point of view, it would be nice to look at Cellular Call Time in iPhone Settings, and know what's legitimately cellular (i.e., you'll be billed for). But now that I think about it, that metric is really high level, and doesn't help delineate what may or may not count towards hitting a "barrier" -- i.e., do you have a bucket of minutes or unlimited, nights and weekends free, etc...? Who knows, various carriers may have different fine print regarding what counts and what doesn't. Probably need a separate app for this...
