A system and method for providing incoming call to a remote device sharing a MSISDN with other remote devices

The invention concerns a method for providing an incoming call, through a cellular network (3), to a remote device (1) sharing a first Mobile Station International Subscriber Directory Number (MSISDN) with other remote devices (1) and having a Subscriber Identity Module (SIM, 2) storing a primary International Mobile Subscriber Identity (IMSI) corresponding to the first Mobile Station International Subscriber Directory Number (MSISDN), the method comprising: - receiving a call from the remote device (1), the call being based on the primary International Mobile Subscriber Identity (IMSI) of the remote device; - establishing a communication channel with the remote device (1) in response to receiving the call based on the primary International Mobile Subscriber Identity (IMSI); - transmitting, through the established communication channel, to the Subscriber Identity Module (SIM, 2) of the remote device (1) a secondary International Mobile Subscriber Identity (IMSI) corresponding to a second Mobile Station International Subscriber Directory Number (MSISDN) with an associated configuration instruction defining a time slot to cause the remote device (1) to activate the secondary International Mobile Subscriber Identity (IMSI) during the associated time slot in order to allow incoming call based on the second Mobile Station International Subscriber Directory Number (MSISDN) towards the remote device (1) during the associated time slot.
