I’ve used wi-fi calling fairly extensively mostly because I’ve lived in areas where there was zero cell service but ready access to internet (via Starlink or other wireless forms of it). One thing I do know is that my phone co. requests that I fill out a form specifying where I am living currently (whilst using it) so that if I ever need to contact emergency services they’ll have a better idea of where to route the call to. For instance my phone number originates from Western BC but I could potentially be using wi-fi calling from anywhere in the province. I mention this to say, it appears my telco doesn’t have a way to triangulate me with this service.
I can further attest that wi-fi call & text reception still works fine when I have a VPN running on the router that my mobile device is connecting to. Make of that information what you wish.
Though that I have read that wi-fi calling is atrocious for privacy reasons that I have not followed up on. Given the above I’m not sure how or why that would be the case, but basically if I’m in an area with cell coverage I turn it off. I’ve always meant to look deeper into how or why it might be bad (or worse) in some way.
Brian Thompson and his co-workers murder hundreds of thousands of people with systemic neglect, spreadsheets, and lawyers. They murder in broad daylight, during business hours. And yet they’re comfortable, well paid, successful people who will never see a day in jail. What they’re doing isn’t even considered a crime.
I hope he doesn’t get caught, also. Because the same laws that protect those fucking ghouls will crush him for bringing attention to the grift.
