is the Verizon Iphone 5 sim unlocked like their other LTE phones such as the Lumia devices or their androids?
Yes,Verizon's iPhone 5 is sold unlocked. However, here in the US it will only work on AT&T and T-Mobile's 3/4G network for voice and data. Verizon's iPhone 5 will not work on AT&T's LTE data network... It will work on a number of international LTE networks. You can find more about Apple's LTE information details and the bands that each specific model of iPhone 5 supports here: Apple - iPhone 5 - View countries with supported LTE networks.
So Verizon iPhones will work on 3G if you have an AT&T sim ?
