I think you've missed the point. Yes, there's a lot of phones around, but there are laptops, desktops, embedded systems, thermostats, doorbells/locks, ..... So it's not about whether a phone uses the mobile network or WiFi, it's about all those other devices that aren't mobile phones connected to networks that aren't mobile phone networks.
