Less so in France: virtually everybody that would sip 2-3EUR coffees has a 19EUR cellular plan with unlimited data. And that's the price if you're not bundling and not playing off providers off eachother.
Can confirm. Having dropped my mobile in the bath (...) I needed wifi yesterday and only the fifth café I tried in provincial France had wifi available. (And that didn't work until I adjusted my settings to use the DHCP server's provided DNS...)
Now I wonder if it's this law that made it not worth the effort for them.
Many EU tourists as well, here you can still get sub GB plans, and unlimited is twice what it is in France, and if you're not savvy, four times is possible too.
Free wifi is for the non-EU tourists.
