Great news for those waiting anxiously at the door for their UPS / FedEx delivery… well, for those awaiting a Verizon iPhone 5, anyway. We’ve already broken down the differences between the trifecta of iPhone 5 models, and it seems that the one VZW is hawking is a real gem for travelers. Aside from handling Verizon’s LTE waves just fine, the nano-SIM slot will also accept cards from any other GSM carrier worldwide. In other words, AT&T nano-SIMs will get you onto its HSPA+ network, and T-Mobile nano-SIMs will play nice as well. If you’re heading overseas, you can pick up a local nano-SIM on arrival and plug it straight in — no unlocking code necessary. To confirm, this even applies to Verizon iPhone 5 units that were purchased under contract.
