Here is my .02 - Not directly related to this subject but kinda/sorta.
I am one of the Ex-Millenicom people. Not finding a better alternative, I signed up for Verizon's offer of 20 gig for $100 (only offered to Millenicom folks in order to keep them in the fold). When I was working with the Verizon tech over the phone to do the switch, one of the questions I asked was 'What happens if the Millenicom MiFi (actually a Verizon MiFi) dies and I need to get a replacement ?' The reply from the customer service tech was that I would lose my special plan and that I would then need to get a 'normal' Verizon data plan. As long as I use my original Millenicom MiFi, the plan will continue in place indefinitely.
If I was in your shoes, I would be leery of making any changes as that could provide Verizon with a reason to bump you out of your unlimited plan.
