1. A wireless communication device comprising:
a transceiver; and
control circuitry configured to:
transmit a registration request message to a first management device that belongs to a first public land mobile network (PLMN) and that manages registration of the wireless communication device,
the registration request message including second PLMN_ID information,
the second PLMN_ID information being also included in first PLMN list information that is stored in a second subscriber identity module and that is stored in a first subscriber identity module,
receive, from a first base station that belongs to the first PLMN, a first paging message related to a first paging that has been generated in the first PLMN, and
receive, from the first base station, a second paging message related to a second paging that has been generated in the second PLMN,
wherein the control circuitry:
specifies a first paging occasion in which the first paging message is arranged and a second paging occasion in which the second paging message is arranged, by using at least one of identification information of the wireless communication device and system information received from the first base station,
specifies a subframe number of the first paging occasion and a system frame number of a first paging frame including the first paging occasion, by using the identification information of the wireless communication device allocated from the first PLMN, and
specifies a subframe number of the second paging occasion, based on the subframe number of the first paging occasion.
