26. What is the separate sale of regulated data roaming services at retail level?

Under the terms of Regulation (EU) 2015/2120 of the European Parliament and of the Council of 25 November 2015https://www.anacom.pt/render.jsp?contentId=1373317, the separate sale of roaming services may entail provision of regulated data services in roaming directly on a visited network, by an alternative provider of roaming services without requiring a change of SIM card or mobile device.

However, offers of this nature need to appear on the market and operators are not required to make them available.
