It would be great if Apple could create their own version of Google Fi, optimized for iOS devices and, more importantly, privacy. This would also be cool for international use, where using my phone feels like playing Russian roulette. Is my Wi-Fi call billed at normal data rate? Am I being billed at $1/minute? Is my call even going over Wi-Fi? If Apple controlled the network, they could just say "This is a free call" on the call screen, or "This call is $0.20/minute." And even better, with flaky international Wi-Fi, the call could be locked into the initial rate even if it hops over to a cell tower if/when the Wi-Fi fails. All I want in a carrier is rock-solid predictability and reliability and for me to never think about it ever again. Google Fi comes really close to this, but it's still not ideal for those using Apple products.
