This article is from a year ago, and since then, the implementation of this has been delayed until at least 2018 [1]. The good news is that the latest drop (last year) of statutory roaming rates has made roaming within the EU much cheaper if you shop around a bit, but we're sadly still far from the way it is in the U.S. where you don't have to think about the fact that you're 1000 km away.
