Absolutely BRILLIANT response -- referring me back to the exact same web pages referenced in my original question. Typical of amazingly low USA literacy rate.

Fortunately for you, I’m not American.

You actually answered your own question:

At this web page T-Mobile network frequencies & technology:

T-Mobile identifies bands, but again, sadly conceals the scheduled timelines.

You failed to read/understand:

These bands are deployed today.  not all bands in all markets.  most markets are B2/B4/B12/B71

Check the link that I sent for what bands (who cares if it is CAT 6), 

If your device supports what is in use.. then you should be good to go.

Giving attitude to those wishing to assist will not help you in this matter, not will claiming elitism from T-Mobile/Bellevue.
