Hello, I received a 4G dongle which is identified as "Quanta 0408:ea45" from my carrier with a static IP assigned to it and I can send up to 1000 SMS via the built-in web-interface located at 192.168.25.1

I attached it to my Linux box with usb-modeswitch installed and I got eth4 with DHCP enabled working fine, got 192.168.25.32 ip address on eth4 from the dongle.

The internet connection is working fine.

However I cannot find any ttyUSB* entries for this dongle, it is identified as a NIC only.

Is there a way I can send SMS messages from the command line in this case?
Can I force the dongle identify itself as both a NIC and a ttyUSB device?

0408:ea45 does not have any serial interfaces, only the direct ethernet interfaces and the interface for the TF/SD card.

There is most likely a built in web server where you can get connection status and probably also read/write SMS.
Web servers usually reside on the same address as you are getting as gateway, maybe 192.168.25.1

There is indeed a web server residing on 192.168.25.1, and I can send SMS from its webpage, but I want to be able to send SMS from the Linux shell (for use in scripts)

You can only do that via the web server, there are no other interfaces than the direct ethernet interface to go via.
Script it using curl or wget/wput.
