EU and mobile phone charges

The EU is forcing mobile phone companies to cut their roaming charges abroad. Sounds nice, yes, but I can't imagine the burden on mobile phone companies, and indeed on domestic consumers - after the last roaming charge legislation my minimum call charge rose from 10p to 15p - will it go up again? Probably.

It also tends to ignore supply and demand, which is the best legislation - they charge too much and I won't make calls abroad - and indeed that's the case.
