Abstract: A method for optimizing cross Subscriber Identity Module (SIM) calling by a User Equipment (UE), comprising: detecting, by the UE, an event associated at the UE, and cross SIM calling is established at the UE; initiating, by the ePDG of the AP, an evolved Packet data gateway (ePDG) at a communication processor (CP) of the UE based on the call being established; and processing, by the CP of the UE, the cross SIM data packets using an IP security tunnel.
