1. A server apparatus comprising:

  • a data communication interface;

    one or more processors; and

    one or more memories including computer program code;

    the one or more memories and the computer program code configured to, with the one or more processors, cause the server apparatus at least to;

    manage, instead of mobile network operators, by a service provider, subscriptions to wireless communication networks as specified by a set of subscriber identity modules accommodated in a personal portable container communicating with a mobile terminal by a short-range radio link;

    maintain subscriber identity module-specific usage records about utilization of the wireless communication networks by the mobile terminal associated with the set of the subscriber identity modules, each usage record comprising a quantity quantifying amount of data transferred with each subscriber identity module and a limit setting the maximum allowed amount of data transfer for each subscriber identity module;

    receive from the mobile terminal, with the data communication interface, information on the amount of the data transferred with each subscriber identity module;

    update the subscriber identity module-specific usage records with the information on the amount of the data transferred with each subscriber identity module;

    compare periodically the quantity in each usage record with the limit in the same usage record, andif the quantity in the usage record is within a predetermined margin of the limit in the same usage record, transmit, with the data communication interface, to the mobile apparatus, a command to limit data transfer speed of the subscriber identity module defined by the usage record; and

    detect a roaming of the mobile terminal, and select the cheapest subscriber identity module to provide a required service, at a required quality of service and at a required data transfer rate, from among the set of the subscriber identity modules, taking into account a location of the mobile terminal and the quantities and the limits defined in the usage records for each subscriber identity module.
