Searches for unlimited mobile proxies usually come from someone who has just watched a per-gigabyte bill climb faster than expected. The word unlimited is doing a lot of work in this market, so this post sets out exactly what it refers to, what it does not cover, and the arithmetic that decides whether it saves you money.
Two billing models, not two products
Mobile proxies are sold in two ways, and the difference is billing rather than technology. Both put your traffic on a real 4G or 5G carrier connection.
Per gigabyte. Our rotating mobile pool is $3.50 per gigabyte pay-as-you-go, $2.97 on the 20 GB package and $2.45 at 100 GB. You get a different carrier IP on each request, sticky sessions up to 30 minutes, and a choice of country or specific carrier. You are buying volume of data.
Per IP per day. An LTE line is $2.00 per IP per day with unlimited data and no metering at all. You are buying time on a device. Rotation happens on demand or on a timer, and the address stays yours while the proxy is active.
Neither is better. They suit different shapes of work, and the shape is defined by one number: how much data a single address moves in a day.
The break-even, and what it looks like over a month
Divide the daily flat rate by the per-gigabyte rate: $2.00 / $3.50 = about 0.57 GB. That is the crossover.
| Data per IP per day | Rotating mobile at $3.50/GB | LTE at $2.00/day | Cheaper |
|---|---|---|---|
| 0.2 GB | $0.70 | $2.00 | Per gigabyte |
| 0.57 GB | $2.00 | $2.00 | Line ball |
| 2 GB | $7.00 | $2.00 | Unlimited |
| 10 GB | $35.00 | $2.00 | Unlimited, by a lot |
Over a month, one unlimited line is $60 regardless of transfer. The same $60 buys about 17 GB of rotating mobile. So the question is never "is unlimited good value" in the abstract; it is "will this address carry more than 17 GB this month".
What unlimited does not mean
Three limits survive the word unlimited, and it is better to know them before you buy than to discover them mid-project.
- Throughput is a radio link. A mobile proxy is a real device on a real cell. Speed varies with signal quality and how busy that cell is, exactly as your phone does. Unlimited refers to the volume you may transfer, not to guaranteed bandwidth.
- The address is shared with real people. Carrier-Grade NAT puts many genuine subscribers behind the same public IP. That sharing is the entire reason mobile IPs carry high trust, and it is also why you cannot treat a mobile IP as exclusively yours in the way a datacenter address is.
- Carrier-side fair use still exists. Networks manage congestion. Sustained saturation of one line is noticed by the carrier, not by your invoice.
None of that is a catch. It is what renting a phone line means, and it is why the price is flat: the constraint is the hardware, not the meter.
When the per-gigabyte pool is the right answer
Unlimited is the wrong purchase more often than vendors admit. Go per gigabyte when:
- You need many identities and each only briefly. Account creation and verification work wants a stream of fresh addresses, and you are paying for addresses, not data.
- Your traffic is text-heavy and light. Scraping HTML with images blocked can run at a few hundred megabytes a day across a whole project.
- Your volume is unpredictable. A per-gigabyte balance absorbs a quiet week; a rented line bills for it anyway. Unused gigabytes stay on the account for 120 days.
Go flat when one address carries real volume for days at a time: long sessions, media or app traffic, device testing, or anything where an unpredictable per-gigabyte bill is worse than a known daily one.
How to decide in one day
Do not model this, measure it. Buy a small amount on the rotating mobile pool, run your real workload for 24 hours through a single sticky address, and read the usage. If it is comfortably under half a gigabyte, stay per-gigabyte. If it is over, switch that address to an LTE line and keep the pool for the short-lived work. Most serious setups end up running both, with the heavy long-lived identities on flat lines and the churn on the pool.
If you are weighing up how many accounts to put behind one address, accounts per mobile proxy covers that trade-off, and every rate is listed on the pricing page.
Frequently asked questions
Are unlimited mobile proxies really unlimited?
Unlimited means no data cap and no per-gigabyte charge: you are billed for time on the line, at $2.00 per IP per day, and transfer is not metered. What is not unlimited is physics. You are sharing a radio cell and a carrier NAT pool with real subscribers, so throughput varies with signal and local congestion the way any phone does.
When is unlimited cheaper than paying per gigabyte?
Above roughly 0.57 GB per address per day. That is $2.00 divided by the $3.50 per-gigabyte mobile rate. A month on one unlimited line is $60, the same spend as about 17 GB of rotating mobile, so if a single IP moves more than about 17 GB a month the flat rate wins, and by a widening margin after that.
How do I know how much data my job actually uses per IP?
Run a day of your real workload on the per-gigabyte pool and read the usage. Most people guess high: text scraping with images blocked is far lighter than expected, while anything touching video, images or app traffic is far heavier. One day of real measurement settles which billing model suits you.
Can I rotate an unlimited mobile IP?
Yes, on demand or on a timer. The port and your credentials stay the same while the exit address changes, so nothing in your code needs updating when it rotates. That is different from the rotating pool, where a new address arrives automatically on every request.
Is unlimited worth it for account management?
It depends on how many accounts. One identity that needs a stable mobile IP for weeks is a good fit for a rented line. Fifty identities that each need a few minutes on a fresh IP are much cheaper on the per-gigabyte pool, because you are paying for addresses, not for data.
