    What should I do if the Signal indicator is solid red?
    When there is no SIM card, no service, or the device is not registered to the network, the network indicator on the router is solid red.
    1) Make sure the SIM card is valid and inserted correctly;
    2) Move the router to an area with a better signal (try placing it near a window).
