Verizon Wireless customers who have an unlimited data plan and use significantly more than 100GB a month will soon be disconnected from the network unless they agree to move to limited data packages that require payment of overage fees. Ars Technica reports: Verizon stopped offering unlimited data to new smartphone customers a few years ago, but some customers have been able to hang on to the old plans instead of switching to ones with monthly data limits. Verizon has tried to convert the holdouts by raising the price $20 a month and occasionally throttling heavy users but stopped that practice after net neutrality rules took effect. Now Verizon is implementing a formal policy for disconnecting the heaviest users.In a statement, Verizon said: "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." a Verizon spokesperson told Ars. "These users are using data amounts well in excess of our largest plan size (100GB). While the Verizon Plan at 100GB 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." FYI: The 100GB plan costs $450 a month.
