T-Mobile compatibility?

So, this device looks pretty sweet. And it might be a good upgrade from my Note 4. The only question I have is, will it get LTE on T-Mobile?

Since this whole sub-forum is dead, I guess I'll have to wait until some people get their hands on it over here.

In Germany are available these networks:

I have the Asian version which was bought in Hong Kong.
I can confirm it doesn't work with O2 and partly with 3 (Three)
When i say partly with 3 (Three) is because it will pick up LTE on the 1800 MHz where available and not the 800MHz
Whereas o2 is completely on the 800MHz range and therefore unhelpful.

4g.co.uk/4g-frequencies-uk-need-know

according to the above link, you can get LTE on frequencies 1800MHz and 2600MHz depending what mobile provider you are with and the availability in your area.

Bottomline, 800MHz/Band 20 isnt supported on the C9 PRO.

My question is are the supported Bands software or hardware enabled??
If it possible to unlock the 800MHz via software??

This is what I found to compare.

T-Mobile uses these bands:
GSM850, GSM900, GSM1800, GSM1900, UMTS850 (B5)
UMTS1700/2100 (B4), UMTS1900 (B2), UMTS2100 (B1)
LTE850 (B5), LTE1700/2100 (B4), LTE2600 (B7), LTE1800 (B3), LTE1900 (B2), LTE700 (B12)

The Galaxy C9 is compatible with these bands:
2G bands: GSM 850 / 900 / 1800 / 1900,
3G bands: HSDPA 850 / 900 / 1900 / 2100,
4G bands: LTE2100 (B1), TD-SCDMA2000, TD-SCDMA1900, LTE1800 (B3), LTE2600 (B7), LTE900 (B8), TD-LTE2500 (B41), TD-LTE2600 (B38), TD-LTE2300 (B40), TD-LTE1900 (B39).

The important numbers to look at are T-Mobile using 850/900/1800/1900 and the C9 getting 850/900/1800/1900/2100. That covers what we need for what T-Mobile calls 3G. Note: What T-Mobile calls G3 is called G4 by other companies. Thus what they call 4G is 4G LTE only. So by these numbers, T-Mobile actually gets 4G. IF I understood correctly what I read :)

As for 4G LTE T-Mobile uses B1/B2/B3/B4/B5 and B12.

Of the T-Mobile bands, the C9 is compatible with only B1 and B3 as well as a bunch of irrelevant ones. This means that if you are in an area where T-Mobile is using B1 or B3, you are in luck and will get 4G LTE. If not, you will have to be happy with 4G.

However, I came here trying to find out how to set it up and which of three slots to put my T-Moblile SIMM card into, so this didn't help me at all.

I hope it helped you!!

SM-C900F should support 800MHz/B20.
Ugh, I finally received the C9 Pro C900F/DS for my wife (got it from Malaysia), and turns out I was mistaken after all: It does NOT have Band 20 (I used 'LTE Discovery' app to check). I was under the assumption that Samsung's "F" models are the global variants, and always have Band 20. I guess I was wrong.
