The fixed allowance is the same within the EU. It's not "no roaming charges", but it is that you must not be charged for occasional fair-use roaming (which is quite a lot of roaming). They can still ban you from roaming if you are living in a different country from your contract provider - you're not allowed to buy a contract in Slovakia and then move to Denmark.

You'd be surprised: I picked up a French SIM when I was on holiday there years ago on a very competitive package (including on roaming)... it's still working and I have been living full-time abroad.
Is it "allowed"? Probably not. What are they gonna do about it, cut me off? Well godspeed and thanks for the years of cheap data.
