Misterious USB dongle

Question

I have this USB stick that seems to have a slot for a SIM and for a SD card. I don't know nothing else about this module. Searching the codes on internet I didn't find anything.

How could I find something out about this? And maybe use it in some way?

EDIT: It is recognized by the operative system (lsusb output Bus 001 Device 009: ID 0b3c:c003 Olivetti Techcenter)

And the kernel logs are:

Answer 1

It looks like a USB GSM/UMTS modem. The kernel logs are compatible. It is (was?) used to connect to internet from a PC using a SIM.

This is one such product: https://m.tomtop.com/it/p-c2070.html

The MicroSD is used to store user data, to use it as a memory stick, or sometimes used to provide management software for the modem

Here superuser question a regarding the MicroSD functionality https://superuser.com/questions/781844/why-mobile-internet-sticks-have-a-microsd-slot

With the case il looks like this:
