This website provides information about the “roam like home” service introduced by the European Union started on June 15 2017.
Although promoted roaming will be completely free for European customers when travelling the EU, this is not 100% the case. In certain cases you still can be billed surcharges. Read through this website and you will get a better picture of “free roaming by the European Union”.
