(EU citizen too) You can't select any network, your home carrier has to have an agreement with the network you select. They're talking about switching operators, not roaming - roaming means your traffic is still routed to your own provider. The concept, if I understand it correctly, is that you'd pay the best offered rate per byte around you at the moment, and your phone would be dynamically switching networks based on the offers. The problem with this is that unlimited plans would go out of the Windows and we'd be back to paying per byte. Not great imho.
