You want the RM-1065. It has all the frequencies you need for T-Mo, AT&T and is a Factory Unlocked world-phone.

B&H has it on pre-order for black... Blue, white and orange in stock now: http://www.bhphotovideo.com/c/search?Ntt=lumia+640+xl&N=0&InitialSearch=yes&sts=ma&Top_Nav-Search=

Or you can search the interwebz for RM-1065, you may find a better price.

You DON"T WANT RM-1067... No LTE and no band 4 you need for T-Mo 3G to work in all areas.
