so where is it? I'm not seeing any sim card slot on any of the pics on apples website??
Do all iPad models use the same type of SIM card?
No. iPad Air 2 with Wi-Fi + Cellular and iPad mini 3 with Wi-Fi + Cellular can use either the Apple SIM card or a carrier-supported nano-SIM card. iPad Air, iPad mini 2 and iPad mini use a nano-SIM card. All other iPad models use a micro-SIM card. Micro-SIM cards cannot be used in devices that use the Apple SIM or another nano-SIM card.
