Notably for mobile users roaming in the EU, this problem has already been solved by the European Parliament:<p><pre><code> Under the wide-ranging telecoms reforms, the cost of making a call
or downloading internet data in another EU country will be the same
as at home.
The change is due to take effect from 15 December next year. It still
requires approval from EU governments.
In recent years the EU has legislated to lower the costs, so telecoms
operators have been forced to cap their fees.
The package was adopted by 534 votes to 25.
