No provider gives away infinite bandwidth. On an unlimited plan the limit does not disappear, it moves somewhere less visible — and knowing where tells you whether the plan suits your work.
Unlimited plans normally mean unmetered traffic through a fixed number of addresses or ports, for a fixed monthly fee. You stop counting gigabytes; you start counting connections. The provider's cost is no longer proportional to your traffic, so it has to be controlled another way.
That control is where the fine print lives: a cap on concurrent threads, a ceiling on speed per port, a smaller pool than the metered product uses, or a fair-use clause that lets the provider throttle the heaviest users. None of that is dishonest, but it is the part that decides whether the plan works for you.
It wins when your traffic is large, continuous and tolerant of a fixed exit set — long-running crawls of a handful of domains, video or media transfer, monitoring jobs that run all day. If you would burn hundreds of gigabytes a month through a small number of addresses, a flat fee is simply cheaper.
It wins whenever your work is bursty or spread thin. Most account management, price checking, verification and ad-checking work sends modest traffic across many addresses and many countries. On a metered plan you pay for what that actually costs, and between projects you pay nothing.
It also wins for anyone who has not yet measured their own consumption, which is most people starting out. A month of an unlimited plan is a commitment made before you have the data to justify it. A gigabyte costs a couple of dollars and produces that data.
Run your real job for a day on metered traffic and read the consumption. Multiply out to a month, compare against the unlimited price, and the answer stops being a matter of opinion. Two numbers, one afternoon.
On PyProxy, traffic is billed per gigabyte and does not expire, so nothing is wasted if the job turns out smaller than expected. Larger packages carry bonus gigabytes, which lowers the effective rate as you scale — the practical middle ground between metering and a flat fee.
Traffic is unmetered, but the plan is bounded some other way: a fixed set of addresses or ports, a thread cap, a speed ceiling per port, or a fair-use clause. Read which one before buying.
Only above a break-even point that depends on your work. Measure a day of your real job on metered traffic, multiply out to a month, and compare with the flat price.
Not here. Traffic you buy stays on the balance until you spend it, which is what makes metered billing safe for irregular projects.
On PyProxy's metered products there is no thread or session limit — you are billed for traffic, not connections. Unlimited-style plans elsewhere are usually the ones with thread caps.
