1. An apparatus, comprising:
a processor configured to cause a user equipment device (UE) to:
perform cellular data communications with a first cellular network using a first subscriber identity module (SIM) of the UE and a first radio resource control (RRC) connection in a first RRC State associated with the first SIM;
determine that communication activity prompts use of a second SIM of the UE, wherein determining that communication activity prompts use of the second SIM comprises determining a paging message is received in the UE;
in response to determination that the communication activity prompts use of the second SIM, transmit a message to the first cellular network while cellular data communications are being performed with the first RRC connection using the first SIM that requests release of the first RRC connection; and
subsequent to transmitting the message to the first cellular network, release the first RRC connection and change RRC State associated with the first SIM from the first RRC State to a second RRC State.
