Verizon has decided that merely throttling the data hogs isn’t sufficient enough.
"Hey buddy, you, the one who is consuming massive amounts of 4G LTE data on your Verizon unlimited data plan and is out of contract. You will want to pay attention to what I’m about to share. Come August 31, if Verizon deems your account as using “an extraordinary amount of data” each month, you could see your line completely disconnected. In other words, Verizon may shut you down by the end of August."
