I suspect it's the network.  One thing you could test is to kill power
to the device, let it be recognized again by the drivers, and re-run
your connect attempt.  If that always works, then either (a) throttling
is done by modem firmware, or (b) restarting the device takes more time
than the network throttles you for.

There is a "Get PDN Throttle Info" command in QMI that isn't hooked up
yet in qmicli, that returns the amount of time left that the APN will
be throttled.  Would be interesting to see for your case, but as I said
unfortunately it's not hooked up in qmicli yet.  Wouldn't be too hard
to add though, if you were interested in doing that.
