@AlanyG21 @fuchsiii @foone in terms of Adaptors to "harvest" if you want to try the cheap USB route, I can recommend the (#4G only but cheap!) #ZTE #MF79U and #Alcatel #LinkKey.

Both basically work out of the box on #Linux and #FreeBSD as #USB-"#Ethernet" adaptors and are essentially portable routers w/o battery.

The MF79U also has WiFi Router Function (2,4 GHz bgn) so it's a practical option that costs <€50 and just works...
