activate the second SIM in accordance with a predefined criteria, wherein the predefined criteria comprises periods of activation and deactivation of each of a plurality of SIMs of different mobile terminals that are mapped to the same subscriber identification number, such that communication is directed to the mobile terminal having the SIM that is both activated during the communication and mapped to the same subscriber identification number without requiring tracking of the user currently filling the position that is shared by the first user and the at least one other user; and

subsequently deactivate the second SIM, wherein the at least one non-transitory memory and the computer program code are configured to, with the at least one processor, cause the apparatus to:

activate and subsequently deactivate the second SIM by activating and subsequently deactivating the second SIM in accordance with a predefined schedule that identifies one or more time periods in which the second SIM is to be activated, and

subsequently deactivate the second SIM by causing a signal to be provided to the at least one mobile terminal regarding activation of the SIM of the at least one mobile terminal, receiving a signal indicative of activation of the SIM from the at least one mobile terminal and deactivating the second SIM in response thereto.

7. An apparatus according to claim 6 wherein the at least one non-transitory memory and the computer program code are configured to, with the at least one processor, cause the apparatus to receive the signal utilizing the first SIM by receiving the signal from a network entity or from the at least one mobile terminal.

8. An apparatus according to claim 6 wherein the at least one non-transitory memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to cause a signal indicative of a successful activation to be provided in conjunction with activation of the second SIM.

9. An apparatus according to claim 6 wherein the at least one non-transitory memory and the computer program code are configured to, with the at least one processor, cause the apparatus to subsequently deactivate the second SIM by receiving a signal with an instruction regarding deactivation of the second SIM.

10. An apparatus according to claim 9 wherein the at least one non-transitory memory and the computer program code are configured to, with the at least one processor, cause the apparatus to receive the signal with an instruction regarding deactivation of the second SIM by receiving the signal from a network entity or from the at least one mobile terminal.

11. An apparatus comprising:

at least one processor; and

at least one non-transitory memory including computer program code, wherein the at least one non-transitory memory and the computer program code are configured to, with the at least one processor, cause the apparatus to at least:

cause predefined criteria to be maintained that defines periods of activation and deactivation of each of a plurality of SIMs of different mobile terminals of a plurality of users who share a position that are mapped to the same subscriber identification number, wherein the different subscriber identification numbers comprise a personal subscription and a professional subscription of the mobile terminal;

cause the SIM of a respective mobile terminal to be activated during the period of activation of the SIM of the respective mobile terminal as defined by the predefined criteria;

subsequently cause the SIM of the respective mobile terminal to be deactivated upon a conclusion of the period of activation of the SIM of the respective mobile terminal as defined by the predefined criteria; and

cause the SIM of another mobile terminal to be activated in conjunction with deactivation of the SIM of the respective mobile terminal and in accordance with the period of activation of the SIM of the other mobile terminal as defined by the predefined criteria, such that communication is directed to the mobile terminal having the SIM that is both activated during the communication and mapped to the same subscriber identification number without requiring tracking of the user currently filling the position that is shared by the plurality of users, wherein the at least one non-transitory memory and the computer program code are configured to, with the at least one processor, cause the apparatus to:

receive a signal utilizing the SIM of the respective mobile terminal with an instruction regarding activation of the SIM of the another mobile terminal; and

subsequently cause the SIM of the another mobile terminal to be deactivated by causing a signal to be provided to the at least one mobile terminal regarding activation of the SIM of the at least one mobile terminal, receiving a signal indicative of activation of the SIM from the at least one mobile terminal and causing the SIM of the another mobile terminal to be deactivated in response thereto.

12. An apparatus according to claim 11 wherein the at least one non-transitory memory and the computer program code are configured to, with the at least one processor, cause the apparatus to cause the predefined criteria to be maintained by causing a predefined schedule to be maintained that identifies the periods of activation and deactivation of each of a plurality of SIMs of different mobile terminals that are mapped to the same subscriber identification number.
