I wouldn't call it "an end", €0.05 extra per MB of data is still very very expensive. It seems like a low number, but people forget it's per MB. Going out, claiming an end to "bill stock", could mean that people will forget that maybe the kids shouldn't be watching Netflix during the holiday, unless they're on WIFI. You still need to disable mobile data when traveling around the EU, because it's not going to be as cheap as using it at home, far from it.
