Good news for anyone using mobile devices in the EU: roaming charges fall dramatically as from today, and will be completely abolished in June 2017. Data roaming is particularly impacted; before today, mobile operators were allowed to charge up to €0.20 per MB, the maximum as of today is the caller's domestic download rate (free for most people), plus a maximum of €0.05/MB.

Something the EU has definitely got right - not so long ago, data roaming charges of well over £1/MB were commonplace.
