Provision of regulated retail roaming services
Article 4
1. Roaming providers shall not levy any surcharge in addition to the domestic retail price on roaming customers in any Member State for any regulated roaming calls made or received, for any regulated roaming SMS messages sent or for any regulated data roaming services used, nor shall they levy any general charge to enable the terminal equipment or service to be used abroad, subject to Articles 5 and 6. 2. Roaming providers shall not offer regulated retail roaming services under conditions that are less advantageous than those offered domestically, in particular in terms of the quality of service provided for in the retail contract, where the same generation of mobile communications networks and technologies are available on the visited network. Mobile communication operators shall avoid unreasonable delays in handovers between networks at internal Union border crossings. 3. In order to contribute to the consistent application of this Article, by 1 January 2023, after consulting stakeholders and in close cooperation with the Commission, BEREC shall update its retail guidelines regarding the implementation of the quality-of-service measures.
