Almost three quarters of Europeans are worried about the cost of using their mobile phone when travelling in the EU a survey released by the European Commission today shows. 72% of travellers still limit their roaming calls because of high charges even if a majority is aware that prices have fallen since 2006. Only 19% of people who use internet-related services on their mobile phones when abroad think the costs of data-roaming for (Internet surfing or checking e-mails) are fair. The results of this survey, plus the public consultation on the future of the Roaming Regulation, which closed on 11th February, will feed into the Commission's review of current EU roaming rules, due by June 2011. The performance target set by the Digital Agenda for Europe is that the differences between roaming and national tariffs should approach zero by 2015.
