1. A method of wireless communication at a user equipment (UE), comprising:
transmitting a registration request to a base station of a first public land mobile network (PLMN), wherein the registration request indicates: (i) a UE configuration as a multiple universal subscriber identity module (MUSIM) device, and (ii) a UE capability for a multi-access protocol data unit (MA PDU) session associated with multiple PLMNs, wherein the MA PDU session includes a plurality of PDU sessions, and wherein each of the plurality of PDU sessions is associated with a Third Generation Partnership Project (3GPP) access type;
receiving, from the base station of the first PLMN, signalling configured to: (i) accept the registration request with the first PLMN, and (ii) provide the UE with an indication of a first PLMN capability for the MA PDU session;
receiving, from the base station of the first PLMN, a list of multiple PLMNs including a second PLMN, wherein each of the multiple PLMNs supports the MA PDU session with the UE, wherein the first PLMN is associated with a first universal subscriber identity module (USIM) of the UE, and the second PLMN is associated with a second USIM of the UE; and
selecting one of the first PLMN or the second PLMN as an anchor PLMN for the MA PDU session.
