The good news that was buried in the iPad Air 2 (and iPad mini 3) announcement was that the cellular models would ship with a carrier-independent SIM card. This meant that users could decide which carrier to activate without being locked in. Unfortunately, the reality isn't quite as straightforward. As we wrote earlier, Verizon still requires their own SIM. But now we're learning that AT&T will "lock" the Apple SIM to AT&T's network the first time you activate it.
