No, the rule says that you can use abroad what you've been using "at home" on a regular basis.

No, as far as I can see all dataplans (in Denmark) differentiate between "at home" and in EU allowance, e.g. I can use 8GB out of 40gb monthly in EU

Anyway, for a typical one week vacation this is a good step forward.
