Thank you for your reply.
In point (3) of your “here is what I see” list, you seem are not correctly understanding what “hologram connect” is reporting.
I am aware that being connected to a provider and creating a PPP connection are separate things. But connecting to a provider (getting your red LED), can be problematic in its own right. I wrote that I have not attempted a sudo hologram connect at this point for emphasis, because I’ve seen on other threads people trying to write this command in a flailing attempt to connect to a provider, and because I want to emphasize that no PPP connection was made by me prior to using the hologram send commands.
My steps prove that no, probably no PPP connection is being made with these send commands, or if one is made, it is momentary.
Which seems to be what you think too:
. . .
are you able to send AT commands to the Nova and see responses?
Yes, using Screen, according to these instructions:

It is how I turned off the NB-IoT radio in the first place to help connecting to a network provider (and get the red LED to illuminate).
. . .
I’d still be interested for someone at Hologram to shout out about how the send commands and PPP are related or not related.
Finally, I have managed now to do a file transfer over a PPP connection. Please see this topic, where I have laid out the steps as best I can:
