Website iDownloadBlog claims it was able to trim down and install a micro SIM card into
the new Verizon iPhone 5, which was purchased under contract, and connect to AT&T's HSPA+ "4G" network.
The publication contacted a Verizon representative who confirmed the handset is indeed unlocked, meaning it can use SIM cards from other carriers even under contract. This is encouraging to travelers who own a CDMA Verizon iPhone 5 but need to hop onto international GSM networks from time to time.

While the installation is anything but elegant, in this case requiring a paper clip and a piece of tape to hold the card in place rather than the supplied tray, AT&T and T-Mobile nano-SIMs are likely to have a better fit.
With the iPhone 5, Apple is implementing new nano-SIM cards that bring a 40 percent reduction in size compared to last-generation micro SIM cards.
