  • Patent number: 9998913
    Abstract: In a management method and a management server for using a plurality of SIM cards, a large number of users can start use easily. First, an MVNO 230A that has obtained one or more SIM cards logs in to a management screen provided by an MVNE 210 in association with a user ID of the MVNO 230A. From the standpoint of the MVNE 210, it is determined whether a user ID of a user who has accessed a management screen of a management server of the MVNE 210 is under MVNO contract (S301). When the user ID is under MVNO contract, an identification number given to each SIM card and a passcode for authentication given as needed are received as registration information (S302).
