Coordinated leaving for a UE having a first SIM and a second SIM may include decoding, at a baseband processor, an RRC reconfiguration message associated with the first SIM received from a first network. A communication corresponding to the second SIM received from a second network is decoded while the baseband processor is processing the received RRC reconfiguration message. The communication received from the second network is determined to comprise a higher priority than the RRC reconfiguration procedure. Based on determining, a UAI message corresponding to the first SIM is encoded by the baseband processor for transmission to the first network. The UM message is configured to inform the first network of coordinated leaving and abortion of the RRC reconfiguration procedure. The first SIM is transitioned to an idle mode. An RRC request corresponding to the second SIM is encoded by the baseband processor for transmission to the second network.
