Can't claim to know that much about cell phone bands, just the comparison I posted. Possibly you could check the bands on you Note to see if consisten with what I've found.
Confusing part is that models for different areas of the world have different bands. I used this site plus the Honor and Lumia support site

Because of different varieties of the same phone,you need to find the model number of the phone, e.g. Honor 6x is BLN-L24. For most phones it's in settings/about phone
There's also this page listing the phones with latest TMO bands T-Mobile B71 Phones
