Correct. I am using a T-Mobile version on att and it works just fine with my microcell.

The only difference between the t-mobile moto x and the at&t moto x is the sim card and APN settings which are changeable.

While the TMO version does in fact have all the AT&T LTE bands (your AT&T SIM will work), the hardware itself does not contain all the same bands as the AT&T version. Our TMO version supports: LTE Band 02; LTE Band 04; LTE Band 17 and the AT&T version supports LTE Band 02; LTE Band 04; LTE Band 05; LTE Band 07; LTE Band 17

Those bands that are missing in the T-Mobile are not used in the US.
With 4.2.2 band 7 is disabled in the AT&T model.
