Oh dear...this is rather bad news

I'm in and out of The Netherlands at least twice a week so this will be a bit of a pain for me.
However, it seems my Callkey based sim (now handled by "simazing") seems to make no mention of these charges
Simazing. Does anybody know if this new rate system will effect all Manx based sims or just those provided through callblue?
I'll be in the Netherlands over the weekend so I suppose the simplest way is to test it and see if charges are made.
