Hi,

Thanks for wiriting to us.

Here, i will suggest you to check the SIM card is being inserted in the device it should be inserted correctly as per the images shown in the first starter link shared below. Also try different SIM card’s in the device, if they are working or not. Initializing means device is try read the card but not able to read it.

if you still faces any issues after performing the steps above, there might be issue with the device hardware so we may need to call the device at our end to check the same, here you need to connect with your sales manager or seller to help with you the next steps.

Thanks
