    Modify Cellular SIM Settings

    Change the primary SIM settings.
    Automatic SIM switchover occurs when the primary or the active SIM fails. The switchover occurs only if there are two SIMs in the ION device and the data session cannot be established for more than five minutes. SIM switchover is limited to only two times when both the SIMs are unable to establish a valid data session—SIM 1 to SIM 2 to SIM 1.
    When the switchover is initiated, if a different carrier SIM is present in the secondary slot, the modem is reset and loads a new firmware. If the secondary SIM is from the same carrier, the modem is not reset.

    Enter the SIM PIN to Unlock the SIM

    The SIM PIN prevents unauthorized use of SIM cards. With SIM PIN enabled, a SIM is locked to a modem. A PIN code is required to unlock the SIM for the modem to access the cellular network and start data sessions.
    The entered PIN is saved in the ION device and this PIN is used for PIN verification when the ION device is reset. PIN verification is not required for an unlocked SIM.
    1. Select the ellipsis icon against the SIM and select
      Enter PIN
    2. Enter the
      PIN Number
       for the SIM.
      The check box
      Remove PIN from Configuration
      is deselected by default. When deselected, the PIN is used to secure the SIM. You cannot use the SIM until the SIM PIN is configured.
    3. Enable PIN for SIM#1
       to enable the PIN for the selected slot.
    4. Save
       to save the configuration.
