Question about Huawei DUPLICATE E3372-325

Hi,

I bought This Stick a few weeks ago, and I use it for my Business Laptop.
It needs a sim card.
It Shows under Windows as LAN-Connection After Findling 4G LTE (does Not Support 5G)

You can use it to access the Internet on the Windows computer on which it is plugged in. It is therefore not really a router, as other devices in the LAN/WLAN cannot use the Internet connection.
