I have a Dell Latitude 7280 on which I'm trying to install Linux. One problem is that I've only mobile broadband. ATM I'm trying to install NixOS but it's unclear if I'll keep it (haven't tried it yet). My computer has a WWAN module (SIM card tray) but I'd like to use an external modem, as I'm swapping the SIM between computers and never have a paperclip to open the damn tray. Anyway,
mmcli -L shows
mmcli -m 0 shows
state: 'failed' and
failed reason: 'sim-missing'. Since SIM isn't missing (the dongle works w/ Linux on another computer), I suspect the reason is that SIM's missing in the internal modem. Two questions:
- Is this conjecture likely correct?
- Is there a way to make the computer to use an external dongle instead of the inbuilt modem?
