As the time of this writing, the Preferred SIM Slot definition as below:

  • Select Auto: To have the Mobile Router (MR) automatically detect and choose the SIM card slot that has a SIM card inserted. If both cards are inserted, the primary Internet connection uses SIM 1, and the cellular backup connection is SIM 2.
    If you change from SIM 1, SIM 2 to Auto, the MR will choose the SIM card slot you previously selected if it has an inserted SIM card.
  • Select SIM 1: To have the MR only use the SIM card in slot 1. There is no cellular backup. If the SIM card is in slot 2, then the MR won't have Internet access.
  • Select SIM 2: To have the MR only use the SIM card in slot 2, select SIM 2. There is no cellular backup. If the SIM card is in slot 1, then the MR won't have Internet access.

Switch when Detach

To enable cellular backup on the MR, enable the switch (to the right).
