USA Carrier compatibility T Mobile?

Having a hard time understanding the numbers, so...

The new Z Pro.  Is this device compatible on the USA T Mobile LTE network ?

It look like T-mobile US use band 2 - 4 and 12 for 4G

https://en.wikipedia.org/wiki/T- ... ency_spectrum_chart

And on the specs for the UMI Z pro it say:
    Band    GSM 850(B5)/900(B8)/1800(B3)/1900(B2)
               WCDMA 900(B8)/2100(B1)
               LTE FDD 2100(B1)/1800(B3)/2600(B7)/800(B20)
So it would appear thats a strike and miss for UMI on T-mobile in the US, but better wait for expert to be sure, i am a veru casual phone user.

It Seems a little bit odd that many smartphones support ALL bands, since the communications circuits from vendors support almost all, so UMI Z leaving behind North America big market (Canada/USA/Mexico) on Band 4 seems strange... Are the cells bands specs right? Aren't they programmable? No use in buying a phone that cannot be used...
