Cisco Sdwan Router LTE Card issue

[Rahul NIrmalkar]

The LTE card is not showing in the Cisco SDWAN Router ISR-4331.

The card shows up after restarting the router 2-3 times. What could be the issue in it?

@Rahul NIrmalkar hi, check if the router firmware version compatibility with card. also check when router reboot, if its detecting card properly or if it throw any issues.
