A $4 Day Pass or Mobile Data by the Gigabyte: an Honest Price Comparison
Published
There are two ways to pay for a US mobile proxy. One is a flat price for a line: with us, $4 for 24 hours of a 4G line that is yours alone, with unlimited data. The other is a shared pool of phones where you pay for each gigabyte your traffic uses and the address changes under you. Both are legitimate products, and we sell a per-GB mobile pool in our own dashboard, so this is not a page about one being good and the other bad. It is about what each dollar buys, where the per-gigabyte bill overtakes the flat price, and which kind of day belongs on which product.
What a flat-rate line is
A line is one SIM in one device we own, assigned to one customer for a fixed period. The price does not depend on how much you move through it: $4 buys a 4G day with unlimited data, subject to a fair-use rule that only starts to matter after seven days of 60 GB each in a plan period, which a day pass cannot reach. You control rotation: by dashboard, link, API, timer or by hand, as often as you like, or not at all, in which case the address stays for as long as the carrier keeps it. The address is in one metro on one carrier, and you can move the line to another metro for free.
The consequences follow from that shape. A line gives you one address at a time, so simultaneous distinct addresses need several lines. A line is exclusive, so the behaviour on its address during your term is yours alone. And a line is a fixed cost, so the more you use it in a day the less each gigabyte effectively costs.
What a per-GB pool is
A mobile pool is a large set of real phones, shared among many customers, with a gateway that hands each request or each short session to some phone in the pool matching your targeting: a country, often a state or city. You buy gigabytes in advance and each byte of traffic draws them down. Addresses come from everywhere in the pool, so a pool offers breadth: hundreds of different carrier addresses across many regions within an hour, without buying hundreds of lines.
The consequences follow from that shape too. You do not control the device and you share it, so the address you were on a minute ago is now someone else's. Stickiness is limited to a short window. And the cost scales with volume: a light day is cheap and a heavy day is expensive, regardless of how many addresses you touched.
Side by side
The table lines up the two products on the things that decide the choice.
| Property | $4 4G day pass (one line) | Per-GB mobile pool |
|---|---|---|
| What you pay for | Time: 24 hours of one device | Traffic: each gigabyte used |
| Data in that period | Unlimited, with a fair-use rule a day pass cannot reach | Exactly what you bought |
| Who else is on the address | Nobody during your term | Other customers, before and after each session |
| Addresses at one moment | One | As many as you open sessions |
| Address change | When you choose; otherwise sticky for hours | Per request or after a short sticky window |
| Location | One metro on one carrier, free moves | Country, state or city targeting across the pool |
| Speed | 4G up to 25 Mbps; 5G line up to 50 Mbps at $5 | Whatever phone the gateway picks |
| Cost of a heavy day | Still $4 | Grows with every gigabyte |
Where the per-GB bill overtakes $4
Mobile pool data, ours included, is sold at $10 per gigabyte, which is two and a half times the price of a 4G day pass. That means the flat line wins on price as soon as a day's traffic reaches a fraction of one gigabyte, which is to say almost any day that involves more than a handful of pages. A morning of browsing deal sites with images, a few hours in a profile browser, an app sent through a VLESS tunnel, or verifying a few video ads will each move more data than the crossover point. The pool wins on price only for a very light day: a few dozen requests, no images to speak of, spread across many different addresses.
The second way to read the same arithmetic: on a flat line the effective price per gigabyte falls all day long, because the numerator is fixed at $4. On a pool it is fixed, because that is what you are buying. If you do not know in advance how heavy the day will be, the flat line is the one whose bill cannot surprise you.
Which days belong on a line
Days that need one consistent US identity: logging into your own accounts, running a profile browser, posting and replying, checking what a site shows to a user in one metro, testing your own app from a real carrier network, tunnelling a phone for a day. Days with any real volume: images, video, downloads, long sessions. Days where you want to control exactly when the address changes. All of these suit the $4 4G day pass, or the $5 5G pass when speed matters, and the weekly and monthly terms when the days add up.
Which days belong on a pool
Days that need breadth rather than identity: touching many different addresses across many states in a short time, where each request is small and no session needs to persist. Checking a handful of pages from twenty cities at once is a pool job; a single line would need twenty metro moves or twenty lines. Days that are genuinely tiny, where the whole day's traffic is a few megabytes. For those, the per-gigabyte price is the smaller bill, and we sell the pool in the dashboard for exactly that reason.
Mixing the two
Plenty of customers run both: a $4 line for the accounts and sessions that need a steady, exclusive US address, and a small balance of pool data for the occasional wide check across many regions. Both appear on the same My Proxies page, both are paid from the same balance, and nothing stops you buying a line in the morning and a gigabyte of pool data in the afternoon. The point of this page is only to make sure the heavy, identity-bound day lands on the flat line, where the bill is $4 no matter what.
Questions about per-GB pricing
Is unlimited data on the day pass really unlimited?
Yes, with a published fair-use rule that counts days of 60 GB or more across a plan period and only acts after the seventh. A 24-hour pass cannot reach it.
Why would anyone buy per-GB data if the line is cheaper for most days?
For breadth. A pool gives many addresses across many regions at once, which one line cannot. For a tiny day of traffic it is also the smaller bill.
Can I get several addresses at once on a line?
One address per line at any moment. For two addresses at once, buy two lines at $4 each; they can be in different metros or on different carriers.
Where do I buy each one?
Both in the dashboard at buy.usa4gproxies.com: lines under the plans, pool data under Buy Proxy on the Mobile tile. Both show on My Proxies.
