LG Watch Urbane 2nd Edition LTE W200 & W200A Difference?

Hello, I'm on AT&T and I want to get the LG Watch Urbane 2nd Edition LTE but I see there is two and im curious about whats the diference? I know the W200a is the AT&T watch and the W200 is an unlocked overseas watch im guessing that will work on AT&T but im hearing If I get the W200 I wont get the LTE, is this true?

Thanks,
