1. A method of wireless communication performed by a user equipment (UE), comprising:
establishing, via a first subscriber service, at least one protocol data unit (PDU) session;
obtaining a first internet protocol (IP) address associated with the first subscriber service;
registering the first subscriber service with an IP multimedia subsystem (IMS) network using the first IP address; and
registering a second subscriber service with the IMS network using a second IP address, wherein the second subscriber service uses the at least one PDU session of the first subscriber service to register the second subscriber service with the IMS network and perform Session Initiation Protocol (SIP) procedures for the second subscriber service.
