# Enable SIM

To enable TelAF Sim Card Service, run the following command to compile the TelAF
            simulation image under the TelAF root
            directory.

    # In Dev PC HOST
    make simulac IMPORT_SDK_SIMULATION=y sdk_rootfs=<path/to/your/generated/rootfs> TELAF_SIMULATION_ENABLE_SIM=y
    Copy to clipboard

    # In Dev Container
    cat >> simulation/.simulation.build << EOF
    export IMPORT_SDK_SIMULATION = y
    export sdk_rootfs=/path/to/your/generated/rootfs
    export TELAF_SIMULATION_ENABLE_SIM = y
    EOF
    
    echo "make simula-c" > simulation/workstation/.simula.dev.action.sh
    make simula-xCopy to clipboard

For now, the remote SIM profile service (RSP) isn't supported in TelAF simulation.

The SDK uses a JSON file to simulate SIM card storage. See [Telematics SDK - User Guide: Telephony
                Simulation](https://docs.qualcomm.com/doc/80-PF458-1/topic/simulation-telsdk.html#telephony-simulation) for more information about how to simulate the SIM card and other
            usage.
