Preordering over dial-up.
My home network on a typical evening at 9pm (Hawaii) runs at 1 megabit if I am lucky. 3 megabit if every porn site on the planet is disabled for my neighborhood.
LTE is 35 megabit.
Phone will try with LTE, home computer on slower network. I expect the phone and apple pay to win.
Currently my best result is with WIFI. Not great reception for LTE where I am.
