Hi Ingo. I don't know of any hotspot device that supports both US and European LTE bands. Even most phones don't support both. The only phone that I know supports all bands you mention, is the "iPhone 6S AT&T/ US SIM-free" model, "Nexus 6P US model" and "Galaxy S6/S6 edge AT&T model"; but band 30 is new, very optional, and not on any other phone I know of. There's other phones that come close: iPhone 6S non-AT&T/International model (missing band 30), iPhone 6 (missing bands 12,30; band 12 is optional, but useful on T-Mobile network for reception in buildings), iPhone 5c/5s (missing 12, 30; missing 7 on US model and 17 on EU model; LTE may work in a limited fashion), Nexus 5X US (missing 30), Nexus 5X Euro (missing 12, 30), Nexus 6 Euro (missing 12, 30), Nexus 6 US model (missing 20, 30; may work limited)

As you can see, only very recent and high end phones have this wide compatibility. I think this is because it's expensive to certify models for frequencies not used in the country of sale. If you're looking to buy a very good new phone then there's some options. Your options widen if you drop the optional band 12 or 30.

If you don't mind multiple devices, there are lots of cheap models now sold on eBay and you can buy one for US use and use your phone tethering in Europe. "MiFi" hotspots are out of style now, since most phones support tethering and the US carriers don't restrict it any more.
