Abstract: A system and method for managing subscriber mobile devices comprising: a home network (400) of a first mobile network operator (MNO1), in which data associated with at least one physical SIM of a subscriber device with an embedded SIM card (eUICC) is obtained, and a destination network (300) of a second mobile network operator (MNO2) which the device travels to, obtaining static data and dynamic data associated with at least one virtual SIM (503, 603) of the device. The dynamic data comprise a subscriber authentication key (Ki) and is obtained from a SIM provider platform (500, 600) on which the destination network (300) relies. The static data comprise IMSI/MSISDN identities and is stored in a pool (202) of the destination network (300). For a given virtual SIM, it is checked whether there is an association in a mapping table (106) of the first mobile network operator (MNO1) between the static data from the pool (202) and the physical SIM data from the home network (400).
