Question to the Department for Digital, Culture, Media & Sport:

To ask the Secretary of State for Culture, Media and Sport, which other countries have introduced a system of domestic national roaming; and whether any analysis has been made of the effect such a system has had on consumer bills, investment and network coverage in each such country.

National Roaming has been implemented in France on a localised level and in Australia on a voluntary basis between two operators, accessible to consumers on a subscription basis. The French and Australian models are outlined in my recent consultation on tackling partial not-spots in mobile phone coverage, however neither model correlates directly to the model of national roaming on which I have consulted.
