MiFi Modem not turning on

I am using gl-inet MIFI as wifi router using sim card and it was working for 2 weeks fine . Last week all of a sudden the 3g/4g modem light went off and the modem light has not turned on even after several hard reset , only wifi symbol is showing. I also verified that the sim card is functioning in a mobile device.

What does it show in the web panel? Can you still see the module?

please find the screenshots attached,

I need the content below what you captured.

The modem is gone. Modem or USB died.

Can you talk with customer service directly?
