摘要: The invention relates to a telecommunications method which enables visited mobile radio telephone network (VPLMN, VPLMN') be connected subscriber of home (HPLMN) without roaming agreements with the (HPLMN). To this end, first IMSI number (IMSI1) from range subscriber's and second (IMSI2) partner (PPLMN) are assigned subscriber. can used via additional agreements, common (MSISDN) is both aforementioned numbers (IMSI1, IMSI2). Both IMSI2) preferably stored on identification module or different modules.
