T-Mobile states:
Key Dates
    As of March 31, 2022, Sprint’s older 3G (CDMA) network will be retired
    As of June 30, 2022, Sprint’s LTE network will be retired
    As of July 1, 2022, T-Mobile’s older 3G UMTS network will be retired

Sadly, T-Mobile conceals which bands those are. Anybody already know what's on file with the FCC?
Or, does T-Mobile just like to give customers a hard time? (Bellevue/Factoria HQ elitism).

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

T-Mobile identifies bands, but again, sadly conceals the scheduled timelines.
Also, T-Mobile conceals the LTE levels required. E.g., LTE-A(5CA) Cat18 1200/150 Mbps; LTE, Cat6 300/50 Mbps.

So, what is the minimum T-Mobile 4G LTE specification, valid through July 2023, for a cheap & destructible used phone, that I can use at a heavy construction site? It's much more efficient to go through 5x $20 ebay 4G LTE phones, than to get a Panasonic Toughbook T1 for $1,000 -- particularly before 5G is widely available in all market segments.

Tmobile has already been on lte for +7 years.

This page has the list you're looking for

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

Strange that they didn't add LTE B41, B25 or B26.

While Sprint has B25/B26, TMobile has deployed B41.  I'm not sure if B25 (extended B2) or B26 (800MHz SMR) will be deployed.

 

This map should help with what is deployed and where.  of course,  2g/3g to de. Be decommissioned

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

@formercanuck’s post is about the best you are going to get.  What runs on 3G/UMTS are also covered by the same bands on 4G/LTE.  Even though Sprint’s CDMA service is being retired.  Band 41 is already being repurposed for 4G/LTE and 5G. Whether or not this will happen with Bands 25 and 26, the information just isn’t available.

Fortunately for you, I’m not American.

You actually answered your own question:

You failed to read/understand:

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.
