Roaming charges - gone in 2017
These new rules will also include net neutrality regulations, which hope to make sure internet service providers (and other businesses) can't discriminate between different services that run on their data networks.
The reason behind all this is to try and make the EU more profitable. The idea is that, with no mobile boundaries, the easier it will be for people to work.
Of course, the people who are making money from roaming charges aren't happy about this. Vodafone and Deutsche Telekom are throwing their toys out of the pram and saying that, by removing roaming charges, this might hamper investment in Europe's mobile and broadband infrastructure.
They're not convinced that there's anything good in reducing the costliness of people using their phones throughout Europe, unsurprisingly. What good could come from people being able to talk more freely from different countries and the like, eh?
"Europeans have been calling and waiting for the end of roaming charges, as well as for net neutrality rules," Andrus Ansip, the European Commission’s vice president for the digital single market, said in a statement. "They have been heard."
