I can only speculate, since Europe is a huge place with multiple telco regulatory regimes and lots of transnational telcos. For example:

- France has a version of STIR/SHAKEN - Germany's Deutsche Telekom has massive presence via local operating entities in poland, austria, czechia etc etc. So it might be that they can assert tighter knowledge of a caller across countries and carriers because its all really DT. - Similarly Orange/Hutchison in France, Austria, and IIRC north Africa.

Beyond that, i dont know.

Could it be due to pricing differences? I have only been in the EU for 6 months, but one thing I noticed when signing up for cell service, is that SMS and Calling is expensive when calling to a different country. For me to call someone in Germany from The Netherlands, it is €0.23/min.

At that rate, scamming someone on the phone from a different country is prohibitive. The other option would be to setup shop and purchase numbers from all EU nations, which is also prohibitively expensive and probably not as easy since LLC's aren't really a thing.

My guess is the large population of the US + the advantageous legal system for new companies is what makes this a unique issue for Americans.
