1. A user equipment device (UE), comprising:
one or more antennas;
one or more radios, wherein each of the one or more radios is configured to perform communication using at least one radio access technology (RAT);
at least a first subscriber identity module (SIM) and a second SIM in communication with the one or more radios;
one or more processors coupled to the one or more radios, wherein the one or more processors and the one or more radios are configured to perform voice and/or data communications; and
wherein the one or more processors are configured to cause the UE to:
maintain, with a network, idle mode connections for at least the first SIM and the second SIM;
transition, upon receiving a first page from the network, a first connection associated with the first SIM to a connected mode;
receive, from the network, a second page intended for the second SIM, wherein the second page includes an indication of an associated paging cause of voice communications;
transmit, to a first access and mobility function (AMF) associated with a first RAT, an indication that causes a release of the first connection and blocks paging from the first AMF that is associated with a lower priority than indicated in the indication; and
initiate a radio connection to a second AMF in response to the second page.
