Living in France since 2012, I get zero French spam calls on my mobile. I'm getting some immediate-disconnect calls from Algerian numbers though (no idea what those are). I used to get silent calls on a landline though, back when I had one (even if I never gave the number to anyone). One fine day I just disconnected it as it was annoying.

I used to get occasional spam calls on my rarely-used old Polish number, but since beginning this year they somehow stopped (late effect of GDPR perhaps?)
