Verizon Communication 's high speed wireless customers who subscribe to the company's unlimited data plans might experience slower speeds.
The compnay said on friday that starting from Oct. 1, it will slow services for the top 5 percent of data users who are on unlimited plans in places where the network is experiencing high demand.
The policy will impact customers who consume more than 4.7 gigabytes in a single billing period who are on unlimited plans and who have fulfilled their minimum contract terms and are subscribing to service on a month-to-month basis.
The policy is currently in effect for unlimited subscribers on the 3G network, but will be expanded to its 4G, higher speed network in October.
