Hi @pravinpharande

Check in Device Manager > Network Adapters to see if the Intel XMM7360 adapter is working OK.

If it is there but not working (yellow exclamation mark or red cross) check that the latest version drivers for the adapter are installed (scroll down the list to find the XMM7360 drivers).

If it isn't shown in Network Adapter, check if it appears in Device Manager > Communication ports or Device manager > Unknown Devices.

Well I will suggest you to check the following:

1.Ensure the WWAN Card is Properly Installed

2.Check If Your Model Has a WWAN Module

3.Check BIOS Settings for that Reboot and enter BIOS and then Go to System Configuration > Wireless or WWAN>Make sure WWAN is enabled> Save and exit BIOS.
