Cisco 829 LTE takes several minutes to turn up the cellular interface. Is this normal?

I'm getting ready to deploy a small fleet of these damn things and I'm finding something odd. About half of them are going into vehicles that aren't on 24/7 and bootup time is a concern.

The router boots in 3 min, sits there calmly with all interfaces up/up hearing MACs from downstream and waits an additional 4 minutes to bring the damn Cell 0 up. I can't find any tuning for this in documentation. Anyone have insight into this?
