The Apple SIM gives you the flexibility to choose from a variety of short-term plans from select carriers in the U.S. and UK right on your iPad. So whenever you need it, you can choose the plan that works best for you — with no long-term commitments. And when you travel, you may also be able to choose a data plan from a local carrier for the duration of your trip.
Apparently T-Mobile CEO, John Legere is a fan of the Apple SIM:
#Apple‘s SIM w/ the new #iPad is huge benefit to all customers, smart ones will bring it to the #datastrong network. #amiright?!
