The Portability Regulation (the Regulation) (EU) 2017/1128 came into force on 1 April 2018. Part of the EU Commission's aim to establish a Digital Single Market, the Regulation facilitates cross-border portability of online content. It allows for subscribed content services to “travel” with the subscriber throughout the entire European Union. Be it movies, sport events, music, e-books, online games, they all need to remain accessible when temporarily abroad in another Member State. Service providers need to make sure this travel option is provided to their customers. Providers of free-of-charge online content services may opt-in but if they do the Regulation applies to the full extent. Importantly, the Regulation applies to both new and existing subscriber contracts.
