Last year, the EU agreed to cap prices of international phone calls:
The European Parliament scored a victory after months of heated negotiations as the European Commission and national diplomats agreed to limit the price of phone calls between EU countries to 19 cents per minute. Text messages will be capped at 6 cents per SMS for consumers within the bloc.
Is this final yet? From when will it be effective? My provider still charges €1.49/minute for calls to another EU country (as of 8 May 2019).
