Abstract:
Methods and devices are disclosed for enabling efficient network registration using a shared radio resource for at least a first and second SIM of a multi-SIM wireless communication device. After the end of a radio-off condition of the radio resource, the wireless device may identify services supported by each of the first and second SIMs, evaluate criticality of the supported services, determine which of the first and second SIM supports the service having the highest criticality, and prevent the other SIM from registering with its network before the SIM with the service of the highest criticality has successfully registered for service in its selected network.
