I'll consider it if I ever travel outside of europe though (roaming inside EU was fixed several years ago luckily).
I can get a local SIM with 50GB data that is available with a 10 euro topup each month.
Don't forget the purchasing power in Europe is much lower than in the US (especially southern Europe). For this reason local carriers are a lot cheaper too.
*Genuinely unlimited data - including tethering, no speed limits or soft caps where you get limited to 128kbps or anything like that after using 100GB.
In my case they clearly have to say upfront on the cheaper unlimited, it's not rate limited until X but the caps have to be proportionate so it's still absolutely fine, they do have an "always on" thing for capped packages though, so you're never really cut off (data only which does not have such strict regulation as voice/SMS)
