Is every iphone 5 4G compatible?

There are a few different iphone 5's

AT&T's model, the GSM A1428, supports the US carrier's LTE network as well as those of Bell (and Virgin), Rogers, (and Fido), and Telus (and Koodo) in Canada. However, its two LTE bands and absence of CDMA support mean there's no slapping in a Verizon LTE SIM and using that carrier's network, nor indeed roaming onto LTE networks in Europe or Asia.

Verizon's CDMA A1429 iPhone 5 comes out on top. That version supports five LTE bands - including three commonly used in Europe and Asia among LTE operators - as well as HSPA+/DC-HSDPA roaming. However, you won't be able to use it on AT&T's LTE, even if you somehow managed to persuade Verizon to unlock it, and - more frustrating in day to day use - there's no support for simultaneous voice calls and data. Instead, Verizon expects iPhone 5 users to rely on Wi-Fi for their data needs while they're making calls.

Finally, there's the single international version offered outside of North America. That, the GSM A1429, supports multiple LTE carriers in Europe and Asia; however it also lacks all support for North America LTE, meaning no 4G fun if you're roaming in the US or Canada.

UK answer as you asked on the UK&Ireland site.

Yes all iPhone 5's are LTE (4G) but not all the networks are and it is not cheap for a 4G contract.

The iPhone 5 Model A1429 (GSM model) is the model that supports the 1, 800MHz frequency that EE are using for their 4G network. You will also need to purchase a 4G bundle from EE - £36 to £56.

The best way to ensure that you are buying the correct model iPhone5 is to purchase from T-Mobile or Orange.EE owns the T-Mobile and Orange brands in the UK and runs a 4G network on 1, 800MHz. You should also check on their coverage map that they are offering 4G coverage where you need it because their coverage is not national yet.
