Abstract: A method for optimizing remote authentication of a virtual subscriber identity module (VSIM) for a multi-subscriber identity module (SIM) multi-standby (MSMS) mobile communication device includes: receiving a VSIM authentication request from a VSIM network; determining whether a previous packet switched (PS) connection between the VSIM and the VSIM network is available; in response to determining that the previous PS connection between the VSIM and the VSIM network is available, performing VSIM authentication using the previous PS connection between the VSIM and the VSIM network.
