Data bingers may have to scale back in October.

Verizon announced Friday that high-speed wireless customers on the company's unlimited data plan may have slower Internet speeds beginning Oct. 1, Reuters reported.

Wireless providers have been working to move customers onto tiered plans, a shift that will charge subscribers for individual data packages. The Oct. 1 change will affect unlimited 4G LTE customers whose data usage is in the top 5 percent of all Verizon subscribers and who are on month-to-month plans, according to The Verge.

The plan, which is already in effect for 3G LTE customers, isn't exactly straightforward since users have to hit all of these marks to be affected. Additionally, the limit only applies when the network is experiencing heavy demand, which will change depending on location.

"If you can check off all those boxes, you'll be subject to throttling and may experience video / music buffering, slower web browsing, and other interruptions that come along with reduced speeds," wrote The Verge's Chris Welch. "And it won't be for just one month: you'll potentially have to deal with throttling the following month, too."

Verizon subscribers who live in a busy city are more likely to experience throttling, while those who are in a less populated area may not. The company has attempted to reassure customers that most won't be affected by the change.

"The vast majority of data customers will not see any impact from Verizon Wireless' Network Optimization policy, and will be able to browse the Internet, stream music and videos, upload pictures and send emails as they always have," Verizon said in a statement quoted by The Verge.
