They will charge you for roaming if you're clearly abusing the system (ie, not living in the place you bought the SIM). How long that takes to happen depends on the individual provider - if they didn't then everyone would predictably just use cheaper eastern Europe SIMs.

Agree but despite the roaming at times it can be way cheaper. For instance paying for BElgium operator (not necessarily the cheapest) you can buy an unlimited 5G (limited to 90G in BE without throttle) which in roaming is 31G costing 25 Eur.

I’ve also seen some cheaper providers than this in DE but they limit 5G to 50mbps :(
