During Apple's iPad event in October they side-stepped their new Apple SIM feature that they knew would controversial. CNBC mentioned it the next day with one analyst calling it "remarkable." In their literature, Apple states that "The new Apple SIM is preinstalled on iPad Air 2 with Wi-Fi + Cellular models. 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." Today, the US Patent & Trademark Office published the patent application that's behind the new Apple SIM.
