How it works
A mobile proxy is a physical modem with a real SIM in it. What makes it durable is not the hardware but the carrier's network design: operators put thousands of subscribers behind a handful of public addresses, so the address you present is one that ordinary customers are also using right now.
Every port terminates on a real SIM in a real handset modem, so the exit address is shared with thousands of ordinary subscribers behind the operator's NAT. That shared history is what makes mobile the hardest class of IP to block outright. Hit the rotation link and the carrier hands back a new address in about 12 seconds; data is unmetered and billing runs per IP per 24 hours.
You pick a country and a carrier at checkout. A modem port on that operator is assigned to your account for the length of the lease and is not shared with another customer.
Your bytes enter the modem's port on our edge and leave through the operator's own network. The public address the target records belongs to the carrier's NAT pool, not to us and not to a hosting provider.
Because that address is shared with genuine subscribers, banning it bans them too. This is the entire economic argument for mobile proxies, and it is why they survive defences that reject residential and datacenter addresses outright.
Call the rotation endpoint and the modem tears down and re-establishes its data session; the operator assigns a new address from its pool, typically within twelve seconds. You can also set a timer between 5 and 60 minutes and let it happen on its own.
The honest limitation: this is one radio uplink. Data is unmetered but throughput is not unlimited — five to fifteen concurrent requests per port is the practical working range, and latency is mobile latency. If you need throughput rather than reputation, this is the wrong product.
Volume ladder
Tiers are a step function, not interpolation: the greatest break at or below your quantity wins and every unit bills at that rate. They apply automatically at checkout — there is no code to enter and nothing to negotiate.
| Quantity | Unit price | Saving | Order total | Order at this tier |
|---|---|---|---|---|
| 1 IP and above | $1.60/IP/day | Entry rate | $1.60 | Order |
| 3 IPs and above | $1.52/IP/day | Save 5% | $4.56 | Order |
| 7 IPs and aboveMost popular | $1.44/IP/day | Save 10% | $10.08 | Order |
| 14 IPs and above | $1.36/IP/day | Save 15% | $19.04 | Order |
| 30 IPs and above | $1.20/IP/day | Save 25% | $36.00 | Order |
| 60 IPs and above | $1.04/IP/day | Save 35% | $62.40 | Order |
| 90 IPs and aboveBest value | $0.96/IP/day | Save 40% | $86.40 | Order |
Totals are what checkout charges for exactly that quantity. Buying past a break lowers the rate on every unit, not only the ones above it. Price a custom quantity in the calculator.
Specification
Everything a reader needs to decide whether this product fits their stack, on one screen and in one table.
| Property | Value |
|---|---|
| Rotation | On demand in about 12 seconds, or automatically on a timer you set between 5 and 60 minutes |
| Sticky duration | Indefinite between rotations — the address holds until you ask for a new one or the timer fires |
| Targeting | Country and carrier, chosen at checkout. The ASN is locked for the lease |
| Protocols | HTTP and HTTPS via CONNECT on port 8080 and 8443, SOCKS5 on 1080 |
| Concurrency | One dedicated modem port. Five to fifteen parallel requests is the practical ceiling of a single LTE uplink |
| Bandwidth policy | Unmetered. There is no overage charge; the radio, not the invoice, is the limit |
| Authentication | Username and password, plus an optional source-IP whitelist |
| Order size | 1 IP to 250 IPs per order, in steps of 1 |
Integration
The credential points at the modem's edge address rather than at a shared gateway, and carries no targeting segments — the SIM decides the country and the carrier. Rotation is an API call, not a username change.
fp_a41c9dfp_a41c9d
The credential id for this modem port.
203.0.113.41
The port's edge address. It is stable for the lease; the carrier address behind it is what changes when you rotate.
Rotation endpoint
POST https://api.fleetproxy.com/v1/leases/{id}/rotate — authenticated with an API key, not with the proxy password.
Automatic rotation
Set an interval of 5 to 60 minutes on the plan and the port re-attaches on its own between calls.
# Force a carrier re-attach. The modem drops its data session and the
# operator hands back a new address, typically in 10 to 14 seconds.
curl -s -X POST https://api.fleetproxy.com/v1/leases/lse_7Kd2p9/rotate \
-H "Authorization: Bearer $FLEETPROXY_API_KEY"Targeting
Mobile targeting is coarser than residential by nature: an operator is a national network, so country and carrier are the two dimensions that exist.
| Control | How it is set | Notes |
|---|---|---|
| Country | Checkout selection | From the markets where we hold SIM estates, listed below. |
| Carrier | Checkout selection | Verizon, T-Mobile, EE, Vodafone or Orange, depending on the country. |
| City | Not available | The carrier assigns addresses from national pools; a city segment would be a claim we cannot keep. |
| ASN | Locked for the lease | The operator's ASN follows from the SIM. Changing it means a different port. |
Mobile inventory depends on a carrier agreement in-country, so this list is deliberately shorter than the residential one.

Use cases
Four workloads where this product is the right answer rather than a workable one.
Registration flows on the large platforms score IP class before anything else. A carrier address with real subscribers behind it clears checks that a datacenter address fails immediately and a residential address sometimes fails.
Apps behave differently on a cellular network: different CDN edges, different bitrates, different feature flags. Testing over a real LTE uplink reproduces what a user experiences instead of what a wired connection reports.
The platforms most aggressive about linking accounts also weight mobile addresses most generously, because their own traffic is overwhelmingly mobile. One port per identity is the standard arrangement.
In-app and mobile-web inventory is bought against carrier signals. Verifying a placement from a fixed-line address checks a creative the campaign never served.

Compare
The two nearest products in the catalogue, and the conditions under which each of them is the better purchase. Buying the wrong class costs more than buying the wrong volume.
$3.40/GB
Choose rotating mobile instead if the job is short. A dedicated port bills for every day it is reserved, so a two-hour campaign on carrier addresses is much cheaper metered by the gigabyte out of the pooled estate — and the pool gives unlimited concurrency, which one modem cannot.
$3.50/IP/wk
Choose static residential instead if the target only distinguishes residential from datacenter. An ISP lease presents a stable consumer identity with rack throughput and no radio in the path, at a lower weekly cost — mobile is worth paying for only where mobile specifically is what gets you through.
Compare all eight proxy types on identity, rotation, targeting and billing, or price them side by side.
Questions
Pulled from the help center and filtered to the questions this product actually raises.
Residential IPs are addresses assigned by consumer ISPs to real subscriber connections, so targets see an ordinary visitor; they cost more and add 200–900ms of latency. Datacenter IPs come from hosting providers, are roughly twenty times cheaper per gigabyte and much faster, but are trivially identifiable and filtered by any site that cares. Mobile IPs are carrier-assigned 4G/5G addresses shared by thousands of subscribers, which makes them the hardest to block and the most expensive. Start with datacenter on undefended targets and residential everywhere else.
Targeting is encoded in the proxy username as segments: user-country-us, user-country-gb-city-manchester, or user-country-us-asn-7922. Country codes are lowercase ISO 3166-1 alpha-2 and city names are lowercase with hyphens. If a segment names a pool that does not exist the gateway returns 407 with an x-fleet-reason header rather than silently falling back to another location.
Roughly 30 million residential addresses across 195 countries, plus dedicated static residential, mobile and datacenter inventory. Coverage is not uniform: the locations pages show live IP counts per country and city so you can check a specific market before ordering rather than after. Anything under 500 IPs in a pool is flagged, because a pool that small will repeat addresses inside a large crawl.
