Hi Marc. First check here if all your 4 countries belong to the common roaming area (green on the map). Then you should buy a SIM in Amsterdam, you first port of entry.

Vodafone is sold at the airport, other brands in town (but not on a Sunday). Stay away from the ethno providers like Lycamobile, as they haven't implemented Roam like at home yet and don't give out data packages at the domestic rate for roaming.

So I guess for 3GB Vodafone will be a good choice. They offer 4G/LTE roaming in almost all EU countries, but limit roaming to their own branded or partner networks. I used Vodafone roaming a lot as back-up within the last year and it was quite reliable.
