For at gøre det muligt for roamingkunder at købe regulerede tale-, sms- og dataroamingtjenester, der leveres som en pakke af en alternativ roamingudbyder, skal indenlandske udbydere, der driver et jordbaseret offentligt mobilkommunikationsnet, stille de netelementer og relevante tjenester til rådighed, der er nødvendige for, at alternative roamingudbydere kan videresælge detailroamingtjenester til den indenlandske udbyders kunder, sideløbende med at der leveres indenlandske mobilkommunikationstjenester, uden at kunden er nødt til at skifte SIM-kort eller mobilt udstyr.
For the purpose of enabling roaming customers to access regulated voice, SMS and data roaming services, provided as a bundle by any alternative roaming provider, domestic providers operating a terrestrial public mobile communication network shall provide the necessary network elements and the relevant services that allow for the resale of retail roaming services, to the domestic provider’s customers by the alternative roaming provider in parallel to domestic mobile communication services without the need for the roaming customers to change their SIM card or mobile device.
