If you encounter the "No SIM Detected" issue with your JL01 or MX2 4G modem, there's no need to worry. This common problem can often be resolved with some simple troubleshooting steps. This article will help you identify and resolve the issue to get your modem up and running smoothly.

  1. Ensure proper SIM insertion
    The first and most crucial step is ensuring the SIM card is inserted correctly into the modem. Follow these steps to ensure a proper insertion:

    1. Power off the modem by unplugging and removing the SIM card.

    2. Examine the SIM card for any visible damage or dirt. If it appears damaged, consider using a new SIM card.

    3. Align the SIM card correctly with the provided guidelines and insert it into the SIM card slot of the modem.

    4. Make sure the SIM card is snugly fitted into the slot.

    5. Power on the modem and check if the "No SIM Detected" issue persists.

  2. Connect the modem directly to the server USB port
    A weak or malfunctioning USB port can sometimes cause the "No SIM Detected" problem. To rule out this possibility, follow these steps:

    1. Disconnect the modem from the USB port.

    2. Connect the modem directly to any USB ports on your server (bypass using USB hubs).

    3. Check if the SIM card is detected.

  3. Test with another SIM card
    To verify if the issue is related to the SIM card itself, try using a different SIM card in the modem. Follow these steps:

    1. Power off the modem and remove the current SIM card.

    2. Insert a different SIM card (preferably from the same carrier) into the modem.

    3. Power on the modem by plugging it back and checking if it detects the new SIM card.

  4. Test the troublesome SIM in another USB modem
    If the previous steps didn't resolve the issue, it's essential to verify if the problematic SIM is working correctly. Follow these steps:

    1. Power off the modem and remove the SIM card showing "No SIM Detected."

    2. Insert the same SIM card into another modem of the same model or a compatible one.

Power on the modem and check if the SIM card is detected.
