This looks like another foul-up by blackberry management. the bands listed are not fully covered by AT&T and if you do a check with AT&T you will find they do not guarantee coverage for the listed bands. It's all related to their license in different areas.
Not sure if T-Mobile is covered.
The phone looks nice but unless they cover the major carriers, Verizon, Sprint, US Cellular, AT&T among others this will be another mss.
The other issue is the off brand name carriers like Cricket also use the majors cell network so they wont work on those also.

the disclaimer in the article states it all

"Although FD-LTE coverage is fairly wide-spread across Canada, we recommend checking the coverage map of your service provider to ensure the best possible experience. "
