Josh Lowensohn, The Verge:
The new technology, called Apple SIM, is only available in the new iPad Air 2 and iPad Mini 3, and limited to some carriers in the US and in the UK.
Dan Frommer suggests that this could "legitimately disrupt the wireless industry." It certainly feels like a step in the right direction. If that happens, however, it's likely many years off. Carrier contracts still lock in a huge percentage of customers.
