Early on I had this obviously naive notion that as long as a Wifi capable phone could connect to a Wifi network, even outside the US, it would identify itself to the phone company… and Wifi calls could reach the phone as well as Wifi calls could be made back home.
But that was never true… and I always wondered why? What’s blocking the connection?
Or what would happen if I were in the UK and used a VPN server in the US? Why would that not work?
