Sorry I just now am replying. If you haven’t tried yet I would take the power hat off and try it without that in the mix.
In case anyone else sees this thread, a quick update.
Looks like IoTDataWorks is now actually throttling to the advertised speed limit on the 64kbps unlimited plans.
For a few months I (like others) was seeing un-throttled speeds of 5Mbps or more. Fun for experimenting. But that no longer seems to be the case.

Still a pretty good deal - if you can handle not having a web dashboard for monitoring your connections, reporting, etc (like Twilio, Hologram, etc).
We use the AT&T LTE-M One Rate Plan, 64kbs but unlimited data. It feels like cheating because we end up using 40-60gb per month on some of these cards. It’s perfect for our use case though.
Unfortunately we haven’t been able to get the card working with the Sixfab HAT yet. Still working towards that. Today we’re only using it in cellular IoT devices.
