Could you explain how this Directive is likely to cause this? It seems significantly more likely, in my eyes, that this Directive will simply end up with even less competition than we already have, as large mobile networks across the EU will buy up smaller ones in other countries in a bid to reduce their costs when their customers roam.

If we want mobile networks detached from mobile infrastructure, we're going to have to legislate that, not piddle around with legislating roaming fees.
