1. A method for wireless communication by a user equipment (UE) having a first subscriber identity module (SIM), a second SIM, and a baseband processor, comprising:
decoding, at the baseband processor, a radio resource control (RRC) reconfiguration message received from a first network and corresponding to the first SIM;
decoding, at the baseband processor, a communication received from a second network and corresponding to the second SIM while the baseband processor is processing the received RRC reconfiguration message;
determining that the communication received from the second network comprises a higher priority than the RRC reconfiguration procedure of the first SIM;
based on determining that the communication received from the second network comprises the higher priority, encoding, at the baseband processor, a UE assistance information (UAI) message corresponding to the first SIM for transmission to the first network, the UAI message being configured to inform the first network of coordinated leaving and abortion of the RRC reconfiguration procedure;
transitioning the first SIM to an idle mode; and
encoding, at the baseband processor, an RRC request corresponding to the second SIM for transmission to the second network.
