Does Unused Proxy Traffic Expire? Pay-Per-GB vs Monthly
What happens to GB you do not use, how prepaid traffic differs from a monthly allowance, and what to check in any provider's terms.
The short answer
Pay-per-GB means you pay for gigabytes, not for a period. Proxy302 sells rotating residential traffic this way on two lines, Budget and Premium, and the traffic you buy has no expiry. If you buy 50 GB and use 5 GB this month, 45 GB are still there next month.
A monthly allowance works differently. You pay for a billing period and the GB come with it. Some providers carry the rest over and some do not, and this page cannot tell you what a given provider does: it is written in that provider's terms or FAQ.
Three ways traffic is sold, and what happens to unused GB
| Item | How you pay | What happens to the part you do not use |
|---|---|---|
| Prepaid GB (Proxy302 rotating residential) | You buy GB or a package for the Budget or Premium line | Nothing: purchased traffic has no expiry |
| Monthly plan with an allowance (other providers) | You pay each billing period for a set number of GB | Set by the provider's terms: it may be lost at renewal or carried over, so check |
| Billed from the wallet as you use it (Fixed ISP, rotating datacenter) | Traffic is debited from the wallet balance per GB | There is no allowance to lose; you pay for what passes through |

What no expiry covers, and what it does not
It covers purchased rotating residential traffic. Traffic bought for one line, Budget or Premium, is spent by proxies of that line, so buy for the line you will actually use.
It does not turn a lease into traffic. A static IP is rented per IP for 1, 3, 7, 30, 60 or 90 days and the lease ends on its date, whether or not you used the IP much. Auto-renew for a lease is optional and can be switched off for each IP.
Prices per GB for traffic that does not expire
| Item | Budget line (US$ per GB) | Premium line (US$ per GB) |
|---|---|---|
| From 1 GB | 1.50 | 5.00 |
| 50 GB package | 1.42 | 4.74 |
| 100 GB package | 1.35 | 4.50 |
| 300 GB package | 1.20 | 4.25 |
| 500 GB package | 1.124 | Not listed |

How to check any provider before you pay
Step 1
Find the sentence in the provider's terms or FAQ that says what happens to unused traffic at the end of the period. If you cannot find it, ask support before paying.
Step 2
Work out whether you are buying GB (prepaid) or an allowance for a period (plan). The price page usually shows it: a per-month price means a plan.
Step 3
Compare on price per GB you will really use. A plan that is cheaper per GB only wins if you use most of the allowance every period.
Step 4
Buy the smallest amount first. At Proxy302 that is 1 GB, and there is no free trial. Run your real task and see how many GB it takes before you buy a bigger package.
