Hi,

If your SIM is not working on your Dell Latitude 5490 (i5 8th Gen, Windows 11 Pro), try these steps to fix the issue:

  1. Check Laptop Compatibility – Not all Dell Latitude 5490 models support SIM cards. Confirm if yours does.
  2. Reinsert the SIM Properly – Power off the laptop, remove and reinsert the SIM correctly.
  3. Enable WWAN in BIOS – Restart the laptop and check if the WWAN module is enabled in BIOS.
  4. Update or Install Drivers – Go to Device Manager > Network Adapters, find the modem, and update drivers.
  5. Check in Windows Settings – Go to Settings > Network & Internet > Cellular, and see if the SIM is detected.
  6. Try Another SIM Card – Test with a different SIM to check if the issue is with your SIM or laptop.
  7. Contact Your Network Provider – If the SIM is still not working, contact your service provider to check for any network issues.

Let me know if you need more help! 😊
