1. An electronic device configured to receive a first subscriber identity module (SIM) associated with a first network and a second SIM associated with a second network, the electronic device comprising:
a transceiver, memory, and a processor which are configured to:
send a first registration request to the first network to register the electronic device, wherein the first registration request indicates that the electronic device is a multi-SIM device, the first registration request comprises a subscriber identifier that is associated with the first network, and the first registration request comprises a multi-SIM policy, wherein the multi-SIM policy informs the first network of capabilities of the electronic device for multi-SIM operations,
receive a page from the second network and, based on receiving the page from the second network, determine to switch to the second network,
send a second registration request to the first network, wherein the second registration request indicates the determination to switch to the second network, and
transition to a CM-IDLE state and an RRC_IDLE state in the first network.
