Just because Verizon Wireless has some customers on \u201cunlimited data plans,\u201d it doesn\u2019t mean that Verizon wants them to actually use it.\nThrottling the speeds of so-called data hogs was a tactic Verizon used before the FCC passed the net neutrality rule. Since throttling is now frowned on by the FCC, the largest wireless carrier in the country has found a new way to keep those pesky customers in line: Subscribers on unlimited data plans who use more than about 100GB a month will be disconnected from the network as of August 31. No calls, no data, no texts.\nIf they want to stay with Verizon, they\u2019ll have to subscribe to a standard data plan with a cap and charges for exceeding it. If, for some reason, those customers need 100GB of data, it will cost them $450 a month. Unlimited plans cost $50 a month and are no longer offered to new customers.You can find details on Verizon\u2019s data plans here: www.verizonwireless.com\/plan.\n[ Related: Verizon will give you 2GB of free data to flirt with Android Pay ]\nI doubt that very many customers --Verizon says it's only about 1 percent -- are directly affected by this move, and I\u2019d agree that 100GB is a heck of a lot of data to use. But there\u2019s a principle here: When a company sells an \u201cunlimited\u201d plan it needs to stick by its agreement with the customer. If it was an unwise offer, that\u2019s on Verizon.\nAfter all, when a consumer signs a contract agreeing to pay for service for a couple of years, he or she can\u2019t decide after six months that it was a bad deal and back out without a penalty. But if Verizon backs out, it gets to say \u201cno harm, no foul\u201d and proceed on their merry way.\nVerizon's side (sort of)\nVerizon, of course, sees it differently, and implies \u2013 but doesn\u2019t actually say or prove -- that heavy data users are causing network problems. Here\u2019s a statement sent to me by Kelly L. Crummey, Verizon\u2019s director of corporate communications.\n\u201cMore than 100 million Americans rely on our network to stay connected to their friends, family and colleagues, and to the information they need. Because our network is a shared resource and we need to ensure all customers have a great mobile experience with Verizon, we are notifying a very small group of customers on unlimited plans who use an extraordinary amount of data that they must move to one of the new Verizon Plans by August 31, 2016.\n[ Related: Verizon touts field testing as rush to 5G intensifies ]\n\u201cThese users are using data amounts well in excess of our largest plan size (100 GB). While the Verizon Plan at 100 GB is designed to be shared across multiple users, each line receiving notification to move to the new Verizon Plan is using well in excess of that on a single device.\u201d\nAlthough unlimited data plans have largely disappeared, AT&T and T-Mobile, do offer them, and throttle the download speeds of very heavy users. The FCC doesn\u2019t actually forbid throttling, but when Verizon announced plans toslow some customers in 2014, commission chairman Tom Wheeler criticized the plan and said he was skeptical of the company\u2019s claim that throttling was needed to manage its network.\nTip of my cap to Droid Life, which first reported Verizon\u2019s plans.
