@Backpacker87 Great info!! Thanks!! I'm curious have you deployed any of these Digi systems yet? If you have I'd certainly be interested in what kind of range you can get and how much info you can pump through. Defiantly going to be digging through your links to see if this might fit the bill.
While hunting for a solution to my problem I came across Verizons Data Plans as well as info on how to use 3rd party sims. Not sure whats the latest on this project tho. Looks like there might have been issues in the past. @rickkas7 has this doc on it.
