In general it's best to talk in terms of "Bands" rather than "Frequencies", as sometimes carriers will use multiple frequencies together to form a single band.
The device you're referring to - presuming it is the EU model - supports the following bands :
3G - Bands 1, 2, 5 and 8
4G LTE - Bands 1, 3, 7, 8, 20, 28, 38, 40 and 41
T-Mobile in the US uses the following bands :
3G - Bands 2, 4
4G LTE - Bands 2, 4, 5, 12, 66 and 71
Clearly the only overlap between those two is 3G Band 2, and even then this is a band that is not available in all T-Mobile coverage areas. It is also 3G only, so if you do get coverage it will at best be slow.
The story is similar with other US carrier. AT&T 4G LTE uses bands 2, 4, 17 and 30 - again giving no overlap. Same for Verizon (Bands 2, 4, 13).
The only carrier with any 4G coverage would be Sprint (Bands 25, 26 and 41), however they will generally only allow approved devices on their network, so your odds of being able to use them are low - plus their band 41 coverage is fairly sparse so even if you could get it connected the coverage would be very bad.
So whilst technically this device will work in the US, the coverage and performance will both be bad enough that if you do bring it with you, you'll probably wish you'd let if at home...
If you do decide to bring it, your best option is probably to use AT&T. Their 3G "Band 2" coverage is better than T-Mobile - but again don't expect too much performance.
