T-Mobile Note Edge on AT&T. topic

I have been searching for an answer and have not gotten a clear and definitive answer. Does the T-Mobile Note Edge variant work on all AT&T LTE networks without issue after being unlocked? According to tbr Samsung website both models have the same bands with the t-mobile Edge have 2 additional bands

I have the att model but would really like to be part of the dev community. I have a week and a half to return my att model. I would buy the t-mobile model if it works completely on the networks. Anyone out there using a t-mobile Edge on ATT. Thanks
