System, methods, and computer program products are provided for interfacing between one of a plurality of service provider (SP) trusted service managers (TSM) and one of a plurality of secure elements (SE). A first request including a mobile subscription identifier (MSI) is received from an SP TSM over a communications network. At least one memory is queried for SE data including an SE identifier corresponding to the MSI. The SE data is transmitted to the SP TSM over the communications network. A second request based on the SE data is received from the SP TSM over the communications network. A third request, based on the second request, is transmitted, over a mobile network, to an SE corresponding to the SE data. The mobile network is selected from multiple mobile networks, and is determined based on the SE data queried from the memory.
