Abstract
A system includes a subscriber identity module (SIM) application; a physical SIM driver configured to be coupled to a physical SIM card; a simulated SIM driver; a control switch that selectively couples the SIM application to the physical SIM driver or the simulated SIM driver, wherein the SIM application, when coupled to the physical SIM driver, is configured to read and write on the physical SIM card; and a SIM simulator in communication with the control switch and the simulated SIM driver, wherein the SIM simulator is configured to control the selective coupling of the control switch, and is configured to receive at least one request comprising an authentication request from the simulated SIM driver and transmit at least one response comprising an authentication response to the simulated SIM driver.
