    Hi,
    is it possible to use Raspberry’s GPIO pins instead of the USB port on the 4G/LTE Shield Kit?
    Thanks

    Yes, It is possible but not recommended. This will limit your connection speed.
    You will need to solder/bridge the UART resistor pads available below the shield.

    So if I have the long header do you mean to bridge pins 8 and 10 in this image?
    pins
    and in the installation process what PORT name do I need to enter?

    Hi Michele, not sure if you’ve solved this yet, so apologies if you have. If you look at the underside of the 4G shield, near the header block you should see four pads labelled ‘UART Resistors’. I believe it’s these need to be bridged.

    Also, did you get an answer about what /dev/ttyXXX interface to use? I would like to know this also.

    Thanks
