Alright, so everything seems to work with the ‘good’ SIM. Here are the logs for a ‘bad’ SIM.
The most relevant issue seems to be:

Your modem APN/password/username may be wrong
Here are the full logs:
clouddebug: press letter corresponding to the command
a - enter APN for 3rd-party SIM card
k - set keep-alive value
c - show carriers at this location
t - run normal tests (occurs automatically after 10 seconds)
enter keep-alive value in seconds (typically 30 to 1380):
keepalive will be set to 30

I’m still learning about the ins and outs of cellular networking, so I’ll start reading up on what a PDP authentication failure might stem from in this context (where this SIM card works in different device, a cellular hotspot) and pass this on to the SIM card provider for additional information. But if you have any follow on thoughts that come to mind that would be great as well! Thanks for the debug tool, very helpful.
Edit: Based on this post on hologram’s forum, my gut says that it’s an issue with Hologram’s activation of the new devices at the carrier level, so waiting to hear back from them and will confirm here if that ends up being the case, though it’s still strange that it worked on the other device.
