Residential proxies are almost always billed by bandwidth — the volume of data that passes through them, measured in gigabytes. Whether those gigabytes have a shelf life has nothing to do with the proxies themselves and everything to do with how the provider structures its pricing. Understanding that distinction is the difference between paying for what you use and paying for what you forgot to use.
What a gigabyte of proxy traffic means
When you route a request through a residential proxy, both the outbound request and the inbound response count toward your bandwidth. Plain HTML pages are cheap; pages stuffed with images, scripts, and media are expensive. You're billed for the data that flows, not for how long you stay connected — so a careful scraper that fetches only what it needs stretches a given balance much further than one that loads every asset on every page.
Subscription vs one-time: the expiry question
Here's where expiry enters. A subscription model charges a recurring fee and typically grants a monthly bandwidth allotment that resets at renewal. If your usage is uneven — heavy during a project, quiet afterward — you pay for gigabytes you never touch, then watch them vanish at the next cycle. The model rewards steady, predictable usage and punishes everything else.
A one-time model flips that. You buy a block of bandwidth as a single purchase, with no recurring charge, and the gigabytes sit in your balance until you actually spend them. Nothing resets, nothing lapses. For the bursty reality of most proxy work — a launch week, a quarterly audit, a one-off research push — one-time bandwidth simply fits the way the work happens.
How the models compare
| Aspect | Subscription | One-time (UNP) |
|---|---|---|
| Recurring fee | Yes, every cycle | None |
| Unused GB | Often reset / expire | Carry over — never expire |
| Fits | Steady, predictable use | Bursty, uneven use |
| Commitment | Ongoing | Pay as you go |
| Risk | Paying for idle GB | None — you keep what you buy |
How Unique Proxies handles it
We sell bandwidth as one-time packages — 5, 10, 25, or 50 GB — with no subscription and no monthly fee. Your GB never expire. Buy what a project needs, use it on your own schedule, and top up only when the balance runs low. Pricing starts at $3/GB for UNP and $5/GB for UNP Premium, each with a 5 GB minimum. There's no idle meter draining in the background between jobs.
That's the whole pitch behind no-subscription proxies: you pay for data, you keep what you bought. For the full breakdown of packages and tiers, see pricing.
