Source: [https://docs.qualcomm.com/doc/80-41102-1/topic/enable-data-call.html](https://docs.qualcomm.com/doc/80-41102-1/topic/enable-data-call.html)

To enable TelAF Data Call 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_DCS=yCopy 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_DCS = y
    EOF
    
    echo "make simula-c" > simulation/workstation/.simula.dev.action.sh
    make simula-xCopy to clipboard

See [Telematics SDK – User Guide: Data Simulation](https://docs.qualcomm.com/doc/80-PF458-1/topic/simulation-telsdk.html#data-simulation)
            for more information about how to use SDK data simulation.

Note: For multi-profile data connection, users need to add
            a virtual interface inside the container and change the /etc/telux/tel.conf
            file. See [Telematics SDK – Network Interface
                Configuration](https://docs.qualcomm.com/doc/80-PF458-1/topic/simulation-telsdk.html#network-interface-configuration) for more information.
