Abstract: According to a first aspect of the present disclosed subject matter, a SIM virtualization system, having servers selected from a group comprising of: eSIM server; SIM server; SIMs bank; and any combination thereof, the system comprising: a SIM-Less mobile terminal having hardware configuration selected from a group comprising of: first configuration; second configuration; and a combination thereof, the SIM-Less mobile terminal comprising: a processor configured to execute SIM virtualization functionalities; a single cellular modem capable of communicating over CH-1 and CH-2 with at least one cellular network; and a non-transitory memory capable of retaining: at least one native SIM profile used by the mobile terminal for emulating a SIM selected from a group comprising of: a universal integrated circuit card (UICC); embedded UICC (eUICC); and a combination thereof; at least one virtual SIM profile; and software stack operative to cause the mobile terminal to obtain and authenticate the at least one virtual SI

Abstract: According to a first aspect of the present disclosed subject matter, a mobile terminal comprises a single cellular modem having concurrent protocol stack that is capable of simultaneous communicating over two channels with at least one mobile network, a logic selector configured to pass authentication information of a SIM to the modem, wherein the SIM can be a physical SIM accommodated in a first slot (native SIM) or a virtual SIM. The terminal further comprises firmware retained in a non-transitory memory operative to cause the mobile terminal to obtain and authenticate the virtual SIM for communicating with the at least one mobile networks, wherein the virtual SIM is obtained from a SIM server connected to a SIM bank that comprises a plurality of SIM profiles.
