I will be moving to the US shortly, and so I have been searching up about phone compatibility. Until I decide on a new phone, I will be using my Lumia 920 (unlocked) that I bought overseas. Below is the relevant information about my Lumia 920. Can I connect to AT&T's LTE/4G/3G?
Solved! Go to Solution.

TL;DR version: GSM 2G/EDGE - yes, 3G - yes, 4G HSPA+ - yes, 4G LTE - no.
According to AT&T's Nokia Lumia 920 phone, here are it's specifications:
4G-LTE Bands 2, 4, 5 and 17
4G HSPA+ with enhanced backhaul
3G - UMTS 850/900/1900/2100MHz
Since the 4G LTE network bands do not match up, my speculation would be that 4G LTE completely will NOT work, but everything, such as 4G HSPA+, 3G and GSM/GPRS/EDGE will work completely fine.
 I also ran into an article on Reddit that shows a guy from Singapore with an International Lumia 920 and his experience on T-Mobile, and on AT&T.
And from his review, he states that he cannot use LTE. But that he is able to use 4G.
quote from article:
AT&T however uses the 700mhz band for the majority of their LTE. The Lumia 920 is missing this band and as a result I have never been on their LTE network despite trying several different APN settings with the assistance of their tech support. AT&T does support the 2100mhz band which the Lumia 920 has but I suspect they have not done a huge deployment on this band yet as I have yet to connect.
