xiaomi mi6 global room

It has more limited LTE frequencies BUT yes it should work.
 
Will this phone work in the USA with the latest global rom (t-mobile)?
I am wondering the same thing. I have a blue Mi6 and I'm getting H+ on T-Mobile in Los Angeles. It's a beautiful phone but I was hoping it would get LTE like the Mix did.
 
The ROM works perfectly with T-Mobile in Austria, even with LTE

As @pkcable said, not all LTE Bands are supported (e.g. Band 20 which is widley used in Europe)
