Mobile vs residential proxies
Quick answer: mobile proxy vs residential proxy
- A mobile proxy exits through a carrier’s 4G network, where many subscribers share one address; a residential proxy exits through a home broadband line.
- Pick mobile for account work and mobile ad checks on one channel; pick residential for data collection across many cities and countries.
- Mobile is usually billed per port, residential per gigabyte; at typical prices ($55 a port, $3.75 per GB) break-even is about 15 GB.
A mobile proxy address comes out of the pool that a cellular carrier hands to phones and modems on its 4G network. A residential proxy address is the one a home internet provider assigned to somebody’s router. Websites can tell the two apart, and so can your invoice: one is rented by the day, the other is metered by the gigabyte. We have sold both since 2016, so we have no reason to steer you toward either.
Mobile proxy vs residential proxy at a glance
Criterion | Mobile proxy | Residential proxy |
|---|---|---|
IP source and ASN | Cellular carrier (4G/LTE); registered to the carrier’s network | Home internet provider; registered to a fixed-line ISP |
People sharing one address | Many subscribers at once, because carriers use carrier-grade NAT | Usually one household; some fixed-line ISPs also share addresses |
Pool size | Thousands per carrier and city; provider-wide pools are smaller than residential ones | Millions of addresses |
Rotation and session length | On a timer or on demand (link or API call); the carrier can also reassign the address | Per request or sticky sessions, usually from a few minutes to 24 hours; the exit device can drop mid-session |
Speed and stability | Follows the carrier’s network load and signal; swings during the day | Set by the home line of the current exit device; changes at each rotation |
Geotargeting accuracy | Country, city and carrier from a shorter country list; location systems see the carrier’s gateway, not the handset | Country, region and city from a much wider country list |
Payment model | Flat fee per port for a day to a month, usually $25–130 for 30 days; pool-based plans bill per GB | Per gigabyte, mostly monthly plans; median $3.75 per GB at 5 GB, $3.00 at 50 GB |
What is a mobile proxy?
A mobile proxy is an intermediary server that sends your requests to the internet through a cellular carrier’s network, so the destination site sees an IP address from the carrier’s 4G LTE pool. Carriers share each public address among many subscribers, which means a mobile proxy address is shared with ordinary phone users.
Most providers sell mobile proxies as ports: a dedicated channel through a device on one carrier’s network, rented for a day, a week or a month, usually with unlimited traffic or a high daily cap. The exit address changes on a timer or when you call a rotation link, and you pick the country, city and carrier.
The limits come from the carrier network: the pool is one carrier’s addresses in one area, speed moves with network load, and the address carries the reputation of every subscriber behind it.
What is a residential proxy?
A residential proxy is an intermediary server that sends your requests through an internet connection in someone’s home, so the destination site sees an IP address assigned by a consumer internet provider. IP databases file such addresses under cable or DSL connections, the same category as a household’s laptop or smart TV.
Residential proxies are usually sold as traffic: you buy gigabytes, choose a country, region or city, and decide how often the address changes, from every request to a sticky session of several minutes.
The limits come from the exit point being somebody’s home connection: the device can go offline mid-session, speed differs from one address to the next, and every image and script you load is billed.
Is a mobile proxy a residential proxy?
People search for a “residential mobile proxy”, a “mobile residential proxy” and “4G residential proxies” as if these were one product. Strictly, they are not. IP databases keep a connection-type field for every network range, and MaxMind, for example, lists Cellular and Cable/DSL as separate values.
The loose usage has a reason: both types sit on consumer networks, unlike datacenter ranges, so some price lists file mobile under a residential heading. What differs is who owns the address, a cellular carrier or a fixed-line home provider.
The confusing case is a phone on home Wi-Fi. The device is mobile, but its traffic leaves through the home router, so a website sees the home provider’s address. The same phone shows a carrier address only on its SIM connection. A “4G residential proxy” built on carrier connections is therefore a mobile proxy under another name, and one built on phones on Wi-Fi is a residential proxy. Ask the seller which it is and look up the ASN of the address you receive; our guide to choosing a mobile proxy provider lists what else to check.
Mobile proxies vs residential proxies: where the difference shows
To compare residential and mobile proxies fairly, we follow the table’s order; each criterion ends with a verdict and its condition.
Address reputation and sharing
A mobile address belongs to a carrier and sits behind carrier-grade NAT, so one address serves many subscribers at once. That cuts both ways: Cloudflare’s research notes that blocking a shared address hits every subscriber behind it, yet its customers rate-limit such addresses three times more often than unshared ones. A residential address usually serves one household, so its reputation is mostly its own.
If a platform sets limits per IP, take mobile when the service is used mostly from phones and you run a handful of sessions; take residential when your results must not depend on other subscribers.
Pool size
Mobile: thousands of addresses from one carrier in one area, and provider-wide mobile pools are smaller than residential ones. Residential: millions. The gap matters only at volume: if a job needs more than a few thousand distinct addresses, choose residential; for thirty client accounts it changes nothing.
Rotation and session length
Mobile: the address changes on a timer or when you call a rotation link, and the carrier may reassign it too. Residential: a new address per request, or a sticky session, usually from a few minutes to 24 hours, that ends early if the exit device goes offline. Choose mobile if you must trigger the change yourself at a known moment; choose residential for many parallel sessions where one dropping is acceptable.
Speed and stability
Mobile speed follows the carrier’s load and signal; residential speed depends on the home line of the current exit device. On average the two are close: in Proxyway’s 2026 benchmark the median response time was 0.96 s for mobile and 0.93 s for residential, and the median success rate on Amazon, Google and Instagram 75.3% vs 74.4%. Both handle text pages and API calls. If you need steady throughput for media or a fixed time window, neither type guarantees it, and a static address fits better.
Geotargeting accuracy
Mobile: country, city and carrier, from a shorter list of countries; location systems see the carrier’s gateway, not the handset (RFC 6598). Residential: country, region and city across many more countries. For city-level work, such as local search positions or prices, choose residential; choose mobile to see what a specific carrier’s subscriber sees.
Residential vs mobile proxies on cost: per gigabyte or flat fee
The seventh criterion is the one you can calculate. Mobile proxies are usually rented per port: a fixed price for a day, a week or a month, often with unlimited traffic or a high cap, so the bill does not change with volume. Residential proxies are billed per gigabyte, mostly on monthly plans, and the rate falls as the package grows.
Which type fits which task
Task | Type | Why |
|---|---|---|
An agency managing client social media accounts | Mobile | Carrier address shared by many subscribers; unlimited traffic covers media uploads |
Checking how mobile ads are shown | Mobile | You see the placement as a given carrier’s subscriber sees it |
Testing a site or app on carrier networks in several countries | Mobile | Real carrier route; you pick the carrier and city |
Marketplace analytics in one country, steady volume above the break-even | Mobile | Flat fee; cost stays the same as traffic grows |
Price and stock monitoring across many stores | Residential | A pool of millions spreads requests; you pay only for the traffic used |
Search position checks by city | Residential | City-level selection with wide country coverage |
Collecting public data from many pages in parallel | Residential | Per-request rotation across a large pool; cost grows with gigabytes |
Sometimes neither type is needed. If one account or back-office tool must keep the same address for months, a static residential IP or an ISP proxy, usually priced per IP per month, is the simpler tool; our guide to ISP vs residential proxies explains the trade-off. If the target does not care about address type, a datacenter IP is the cheapest, and datacenter vs residential proxies shows when that is enough.

FAQ
Can mobile proxies be detected?
Yes. IP databases label carrier ranges as cellular, and sites also read browser and behavior signals. What a site cannot tell from the address alone is which of the many subscribers behind it sent a given request.
Are residential proxies illegal?
No, not in themselves. Routing traffic through a proxy is a lawful network technique. What can break the law or a site’s terms is the activity carried out through it, or addresses taken from device owners without consent.
What is the best type of proxy?
There isn’t one. The choice depends on three things: how the target treats carrier addresses, how many locations you need, and monthly traffic. Below your break-even volume (about 15 GB a month at typical prices) or across many cities, residential; heavy traffic on one channel, mobile.
Is a 4G proxy the same as a mobile proxy?
Yes. “4G proxy” and “LTE proxy” name the network generation; “mobile proxy” names the address owner, a cellular carrier. A phone on home Wi-Fi is not one, because its traffic leaves through the home provider’s address.
