  • Error 1: Blinking Red - Please check the connection of XBLink Duo (Cellular Antennas, Satellite Ethernet cable, Power, etc.) and ensure your SIM cards have an active data plan.

  • Error 2: Solid Red - Please insert SIM cards or connect the XBLink Duo with Satellite device.

If the main LED blinks both a blue and other colors as shown below.

  • Wait another 15-30s for the device to automatically switch between Cellular networks and Satellite to find the best available internet connection in your area.

  • If after this period the internet connection is still not available, check whether the satellite device has a clear view of the sky (not blocked by a roof, trees, etc.). If it is clear and the issue persists, restart either the xblink or the satellite device.
