Abstract: The invention relates to a method for enabling a combination of several individual products (product bundle) to be identified clearly in order to track said products according to the components thereof for the sale and premiumization thereof when said product bundle is purchased. The product bundle comprises a mobile radio terminal and SIM card. A clear material Number is allocated to the mobile radio terminal and a clear chip card Identification Number (U)ICC-ID is allocated to the SIM chip card. According to the inventive method, the mobile radio terminal and the chip card are combined with each other in an EAN data bank by means of the Material Number of the terminal (optionally IMEI) by means of a European Article Number (EAN) for said product bundle. Combination to form a new product makes it possible to market terminal-specific and/or service-specific packets with mobile radio cards in a package/bundle.
