Unlimited bandwidth is a proxy plan feature that removes any fixed cap on the amount of data a customer can transfer during a billing period. Instead of paying per gigabyte, customers pay a flat rate no matter the total usage.
The provider builds pricing around factors other than raw data volume, such as the number of concurrent threads, IP pool size, or connection type. Because there is no gigabyte counter attached to the account, heavy usage does not trigger overage fees or throttling based on data volume. Providers typically still apply reasonable use limits tied to thread count or request rate to prevent abuse of shared infrastructure. This model works well for large, data-heavy projects like continuous scraping or streaming tasks.
This is largely a plan and configuration choice, not a technical limitation.
USER-unlimited-bandwidth-session-task01Everything lives in the username -- add "unlimited-bandwidth" to any proxy credential to apply unlimited bandwidth to a single task. Swap "task01" for a new label to spin up an independent, isolated identity.
KnoxProxy sticky sessions persist up to 30 minutes on residential (60 on mobile), and the window refreshes with activity.
Each session or connection label gets its own exit, so parallel identities never collide.
This costs nothing beyond bandwidth -- successful responses are billed, not the session or connection itself.
Run as many parallel sessions or connections as the job needs -- concurrency is not capped on any plan.
A company running constant large-scale scraping jobs picks an unlimited bandwidth plan to avoid tracking gigabyte usage and unexpected overage charges.
Unlimited bandwidth plans give predictable, flat-rate costs for data-heavy operations, removing the risk of surprise bills. Buyers should still check for other limits, like thread caps, that can affect real-world performance.
Most unlimited plans still apply fair use policies or thread and connection limits to prevent abuse. There is no hard data cap, but limits still exist elsewhere.
Datacenter proxies most often come with unlimited bandwidth plans. Their infrastructure costs scale differently than residential or mobile IP pools.
