Consider that the 4G connectivity device from the ISP probably needs to be on
BEFORE the PC connects to it. [I swear we've had almost exactly this message
before in one of the other threads].

The hotspot connects to 4G then serves out DHCP addresses - if you were using
WiFi, you'd get a WiFi connection. The hotspot is probably not meant to be
switched on and off repeatedly but to be used for a peroiod of hours 
per session.

1. Turn hotspot on. Check that it is working by using the app and/or 
connecting another device and checking connectivity.

2. Boot Debian.

3. Obtain Web connectivity *Profit*

If you're turning the PC on and off with a USB device physically connected, 
it's no wonder that things get confused - *especially* if USB enumeration
is unclear as to what sort of device it is.

I note also that you apparently have a cap of 2GB per month: in that situation
I'd not use a netinst to install anything but it does seem a crazily low
data amount for 30 days.

All best, as ever,
