Nope, have zero use for cell cams, as I visit and move my cameras frequently.  Plus, every video is 50 MB.  Imagine trying to send hundreds of those by cell signal (which doesn't exist on most of my property).  So far, for these cams in particular (Browning Dark Ops Pro Duo, HP4s and HP5s) I get a full season (Aug to early January) out of a set of 8 lithium AAs (12 for the Duo).  That's hundreds and hundreds and hundreds of 10 second videos per camera.  Although I did have one camera that was getting low towards the end of December last year.  Kept cutting night videos short, but day videos fine.  Must have been the power demand of the flash at night.
