Data use doesn't appear to matter, just as before. Some of these units had used very little data (no more than a couple hundred MBs over 30 days) while others had used several GB.

I want to add in fairness that I have purchased several devices from another proprietor which are experiencing the same thing HOWEVER this guy was at least honest and explained that Verizon is doing the throttling on the accounts on the network side, which is more or less what I expected when this whole fiasco began in March.
