What are mobile proxies? They are proxy servers that send your traffic to the internet through the SIM card of a cellular carrier: at ProxyFarm that means MTS, Beeline, MegaFon or Tele2. To a website, every request looks like it came from an ordinary subscriber on a smartphone, because the IP address belongs to a mobile network operator rather than a data center.
This article is for anyone who runs several social media accounts, manages advertising accounts or tests services for a mobile audience. We will look at how mobile proxies work, why rotation matters, where the limits are and in which tasks a mobile channel is simply not worth paying for.
What mobile proxies are and how they differ from datacenter proxies
A regular datacenter proxy is a virtual machine in a hosting facility with a dedicated IPv4 address. That address sits in a hosting provider's range, and any website can look up its ASN in milliseconds and conclude: this is a server, not a person. A mobile proxy is built differently. It is a physical device (a modem or a smartphone) with a SIM card, connected to a proxy farm, and its traffic leaves the network through a carrier's base station.
The IP address of a mobile proxy belongs to the cellular carrier. Millions of real users browse from those addresses, so platforms have little incentive to block them outright. As a result, actions from a mobile IP are judged against softer thresholds than actions from a datacenter IP.
ProxyFarm runs its mobile proxies on its own farms in Moscow, Saint Petersburg and Kazan, 1 284 devices in total. Each device is a separate modem with its own SIM card, and you connect to it over HTTP(S) or SOCKS5 on a single port.
CGNAT: why thousands of subscribers share one mobile IP
The world ran out of free IPv4 addresses long ago, yet carriers serve tens of millions of subscribers. So they use CGNAT (Carrier-Grade NAT): inside the network each subscriber gets a private address from the 100.64.0.0/10 range, and everyone reaches the internet through a small pool of public IPs. At any given moment, one public address is shared by hundreds or thousands of smartphones.
For proxies this is the key property. If a platform blocks a mobile IP, it blocks thousands of its own users in that area along with it. Anti-fraud systems know this, so instead of banning by IP they look at behavior, browser fingerprint and account history. A mobile IP forgives things that would get a datacenter IP blocked.
The flip side of CGNAT is that address reputation is shared. If one of your IP "neighbors" misbehaved, you will see the same captchas. On ProxyFarm's farms every IP is checked against spam databases and target platforms before it is handed over, and an address that does not fit your task is replaced for free within the first 24 hours.
How IP rotation works on mobile proxies
When a modem reconnects to the network, the carrier assigns it a new public address from its pool. Rotation is built on exactly this: the proxy server programmatically drops the modem's connection, the device re-registers within 5–15 seconds and receives a different IP from the same carrier in the same region.
There are three ways to trigger an IP change:
- By link. Every channel has a personal URL; a request to it changes the IP. Easy to embed in scripts and account farms: switch account, hit the link.
- By timer. Set an interval, say every 10 minutes, and the address changes on its own.
- Manually from the dashboard, for one-off tasks and checks.
Rotation never changes the carrier or the city. If you need an IP from another region, you take a separate channel on a farm in another city. ProxyFarm offers a choice of Moscow, Saint Petersburg or Kazan and four carriers.
Limits of mobile proxies: TCP connections, speed, latency
A mobile channel is not a gigabit server line. Three limitations worth knowing before you buy.
- Number of concurrent TCP sessions. The carrier keeps a NAT table per subscriber and starts dropping connections once several thousand are open at once. That is plenty for a browser and a couple dozen accounts, but not for aggressive multi-threaded scraping.
- Speed. A dedicated ProxyFarm device delivers up to 40 Mbit/s. On a shared channel the bandwidth is split between several customers, so real throughput is lower and depends on how busy the base station is.
- Latency. Ping over LTE is usually 40–120 ms versus 5–20 ms from a data center. Unnoticeable for social media, critical for trading bots and games.
Traffic on ProxyFarm mobile proxies is unlimited, but because of the TCP limits you will not pull terabytes a month through a single channel. It is a tool for different jobs.
What mobile proxies are used for
Mobile proxies make sense where a platform pays close attention to IP type and account history. Typical tasks:
| Task | Why mobile | What to pick |
|---|---|---|
| Multi-accounting on Instagram, TikTok, Facebook | Social networks throttle sign-ups and actions from datacenter IPs; mobile IPs are treated as "home" users | Shared channel for 3–5 accounts or a dedicated device for 10–20 |
| Warming up and running ad accounts | Fewer reviews and document requests | Dedicated device, one carrier per ad account |
| Avito and other classifieds sites | Marketplaces match the IP against the profile of an ordinary seller on a smartphone | Shared channel with rotation by link |
| Testing apps and geo-targeting | Requires real carrier traffic, not an emulation | A channel on the required carrier for 1–7 days |
| Messengers: Telegram, WhatsApp | Registration and verification go more smoothly from a mobile IP | Shared channel, SOCKS5 protocol |
Mobile proxies or IPv4: when you don't need mobile
Paying extra for a mobile channel is justified only when the platform actually distinguishes between IP types. In every other case a dedicated IPv4 proxy from 79 ₽ (≈ $0.85) a month does the job cheaper and faster.
| Criterion | Mobile proxies | Dedicated IPv4 |
|---|---|---|
| Price | from 490 ₽/mo for a shared channel, 2 500 ₽/mo per device | from 79 ₽ per IP per month |
| Trust from social media anti-fraud | High, carrier IP | Medium, datacenter IP |
| Speed and ping | Up to 40 Mbit/s, 40–120 ms | 100+ Mbit/s, 5–20 ms |
| Changing the IP | By link or timer, no extra charge | Static address |
| Multi-threading | Limited by carrier NAT | Hundreds of threads |
| Clean history | Address shared with subscribers | One address, one customer |
You do not need mobile proxies if you scrape public sites without strict anti-fraud, monitor marketplace prices, work with service APIs, keep one account per platform or need stable speed for large volumes. Here a static IPv4 or rotating proxies with a new IP per request from 1 490 ₽ (≈ $16) a month win.
Shared channel or dedicated device: how to choose
A shared channel is one device used by several customers. Everyone sees the same external IP, and any of them can trigger rotation. For 2–5 accounts and light workloads this is enough, and such a channel costs from 490 ₽ (≈ $5) a month.
A dedicated device at 2 500 ₽ (≈ $26) a month is a modem that is entirely yours: only you control rotation, the full 40 Mbit/s belongs to you, and the IP history depends solely on your actions. It is the choice for ad accounts, farms of 10+ accounts and customers who value predictability. Teams running dozens of devices can take the corporate plan from 18 000 ₽ (≈ $190) a month.

Related questions
How do mobile proxies differ from residential proxies?
Residential proxies use IP addresses of home internet providers, mobile proxies use addresses of cellular carriers. Platforms treat both as "user" IPs, but mobile ones are more resistant to blocks thanks to CGNAT, while residential ones offer a choice of 48 countries and city-level targeting. ProxyFarm bills residential proxies by traffic from 290 ₽/GB, and mobile proxies monthly with unlimited traffic.
How many accounts can I run on one mobile proxy?
On a shared channel, 3–5 accounts of the same platform; on a dedicated device, 10–20, provided you change the IP between sessions and keep a separate browser profile for each account. Beyond that there is a risk the platform will link the accounts by fingerprint and activity timing.
Can I choose the carrier and city of a mobile proxy?
Yes. MTS, Beeline, MegaFon and Tele2 are available on farms in Moscow, Saint Petersburg and Kazan. The carrier and city are fixed per channel; rotation only changes the IP within that carrier's pool.
How can I verify that a proxy is really mobile?
Open an IP checker page through the proxy. For a mobile address the ASN field will show a cellular carrier (for example, MTS PJSC or PJSC MegaFon) and the connection type will be mobile or cellular. For a datacenter proxy you will see the name of a hosting provider instead.
