Abstract: A user equipment (UE) device performs fast network camping when multiple SIMs of the UE device are out of service. A first software stack begins scanning for available networks and finds an available network at a frequency X. The first software stack decodes system information received from the available network at frequency X and determines that the available network is mapped to the SIM associated with a second software stack of the UE device. The first software stack signals the second software stack that an available network is mapped to the SIM associated with the second software stack at frequency X. In response to receiving the signal, the second software stack sends an attach request to the available network and completes a network attach procedure.
