They vary widely. See
https://cellphonesignalbooster.us/blog/lte-frequencies-and-bands-of-cell-phone-carriers-in-usa-canada/
T-Mobile uses 1900 MHz Band 2 LTE, 700 MHz Band 12 LTE, 1700/2100 MHz
Band 4 LTE.
And see https://www.frequencycheck.com/countries/germany for example.
Germany uses Band 3 (1800+), Band 7 (2600) and Band 20 (800 DD). I see
no overlap with T-Mobile US frequencies, but sometimes phones have
hardware for bands not used by the carrier.
