The impact of data roaming charges on EU citizens was the subject of discussion and debate in the EU for many years. Ending roaming charges was a key foundation of the EU’s Digital Single Market, and an important step in building an accessible, sustainable digital society for all citizens. After many years of work, on June 15, 2017 the EU achieved this objective: mobile roaming charges for calling, sending text messages and mobile Internet no longer apply when citizens use their mobile phone in another EU country. Citizens are now able to make use of these mobile services for the same price... that they would pay if they were at home. In 2017 a survey was commissioned by the European Commission to measure awareness about the abolition of roaming charges, and the impact this has had on citizens’ mobile use when travelling. This current survey follows on from the one in 2017, to assess the impact this change has had one year later. It covers the following: - Travel within the EU in the last 12 months; - Awareness of the end of roaming charges; - Perceived benefits of the end of roaming charges; - Perceived costs of roaming amongst non-travellers; - The use of mobile phone services in other EU countries, including steps taken to restrict use. Comparisons will be made with the results of the previous survey.
