On the Verizon website a PDF document has been found that says the company will begin to throttle the data-throughput speeds of customers that consume huge amounts of data. The PDF reads:
"Verizon Wireless strives to provide customers the best experience when using our network, a shared resource among tens of millions of customers. To help achieve this, if you use an extraordinary amount of data and fall within the top 5% of Verizon Wireless data users we may reduce your data throughput speeds periodically for the remainder of your then current and immediately following billing cycle to ensure high quality network performance for other users at locations and times of peak demand. Our proactive management of the Verizon Wireless network is designed to ensure that the remaining 95% of data customers aren’t negatively affected by the inordinate data consumption of just a few users."
So, will this effect you? Most likely no, unless, you are one to constantly tether data from your device in large amounts and very often.
