"Unlimited" means something completely different to Verizon than it's common usage. It is merely a marketing catch phrase. The use of the word Unlimited, in Verizon's lexicon is nothing but a big fat lie.
You will be limited. Your allotment will be exhausted in a couple days if not a matter of hours. (eg: streaming video eats your "Unlimited" bandwidth allowance up in a few hours)
The reps lie to get you to sign up. They lie not only about the meaning of the word Unlimited, but also about the features, performance and prices of both plans and equipment.
Then the real fun begins [NOT] when you find out you are, in fact, very limited, and they try to tell you the Verizon definition of the word "Unlimited". LoLz!
Avoid this shyster outfit at all costs.
