Just had a look at Ubigi, which I used when on vacation in Japan, and they sell a data only recurring monthly Germany 20 GB data subscription for 19 USD. It's 8 USD more if you want all of Europe. So a bit more pricey. I haven't looked at other vendors, but I don't think there is anything special with my choice of data esim vendor, nor their prices. I haven't seen anything, on their pages, that indicates, that there are stay limits, and if there where, you would expect them to flag that? I wouldn't view these prices as expensive, and they seem not that far from what I pay I Norway. But what is cheap for some, is expensive for others, so what do I know?

This also won't help with coverage, of course, and if you want a phone number, you would need an extra SIM for that.
