Roaming charges will be abolished and net neutrality rules introduced in Europe after lawmakers voted through the proposals.
The European Parliament approved both bills without amendments on Tuesday, two years after they were proposed as part of the European Commission’s Connected Continent reform.
The vote is the final hurdle the two proposals had to overcome before being enacted in law.
Roaming charges will be a thing of the past from 15 June 2017, while all network traffic must be treated equally as part of new open internet regulation.
On the latter, operators are still able to offer specialised services, such as the improved internet quality needed for certain services, but only on condition that this does not have an impact on general internet quality.
Commission Vice-President Andrus Ansip, responsible for the Digital Single Market, said: "The voice of Europeans has been heard.
“Today's vote is the final result of intense efforts to put an end to roaming charges in the European Union and to safeguard the open internet.
“This is the culmination of hard work by the Commission, and in particular by former Vice-Presidents Viviane Reding and Neelie Kroes, to tackle high roaming charges.
“This is not only about money; this is about bringing down barriers in the Digital Single Market.
Ansip added that this was “a first step” towards a telecoms single market. He said: “More work will need to be done to overcome national silos and address challenges such as spectrum coordination.
“We will go further as early as next year with an ambitious overhaul of EU telecoms rules.
“We count on the support of the European Parliament and Member States to make this happen."
