I just bought a brand new iPhone SE from an official apple reseller a few days ago. I do not plan on turning on the phone or activating it until I need to use the phone. Does warranty begin from the date the invoice was issued? Or based on the actual day I first activate my iPhone? My phone has yet to be activated as reflected when I check the serial number on apple's site. I know the Apple T&Cs mention that it begins on the date the item was purchased. But if I am "unable" to produce the invoice how would it work? Wouldn't they just base it off the activation date? I'm always hearing 50/50 responses whether it's purchase or activation date.
