1. Check for Input Errors

      1.1 APN, Username, and Password:

• Double-check for typos in the information you entered.
• Ask your carrier if the APN, Username, or Password details have changed.
• Check this article to know all about APN.

      1.2 Re-enter the SIM Activation Screen:

• Make sure the information you entered is displayed correctly.
• If the displayed data looks wrong or isn't saving, it could be a firmware or software issue.

      1.3 Re-run SIM Activation:

• If you've replaced your SIM, even with the same carrier, you must restart the SIM Activation process.

2. Check Device Settings

      2.1 LTE Setting:

• Make sure the LTE setting is ON in the firmware.
• If OFF, the device won’t connect to the cloud even if the carrier connection works.

2.2 Cloud Service Setting:

• Ensure the Enable Cloud Service setting is ON.
• If this is OFF, the dashcam won’t connect to the cloud even if it has an LTE or Hotspot connection.

3. Check Your Carrier’s Policy (Check with your carrier)

       3.1 IMEI Registration:

• Some carriers need your dashcam's IMEI number registered in their system before the SIM works.

       3.2 IoT Device Support:

• Verify that your carrier supports IoT devices like the dashcam.
• Some carriers may restrict USIM cards to specific devices.

      3.3 Carrier Lock:

• Check if the USIM is locked to a specific carrier.
• Carrier locks can happen during cross-platform use or regular operation.

      3.4 LTE Network Availability:

• Insert the USIM into a smartphone to check if LTE is working in your area.

      3.5 LTE Band Support:

• Ensure your carrier’s LTE band is compatible with your dashcam.
• Example: Verizon (USA) might have connectivity issues in certain areas due to band differences.

4. Check the Dashcam and Modem

      4.1 SIM Insertion:

• Make sure the SIM card is correctly inserted into the modem.
• If the SIM card is not inserted correctly, you’ll hear the voice prompt: "Please insert SIM card."

      4.2 Compatibility: Check if your CM100G LTE / LTE Dashcam is designed for your region.

• Example: The CM100G LTE (NA) model cannot be used in Europe.
• You can find regional compatibility details on PSN (check the PSN guide).
