A mobile proxy is an intermediary server that forwards your requests through a real mobile device connected to a cellular network via a physical SIM card. Because the exit IP belongs to a mobile carrier's address space—the same pool used by millions of ordinary phone subscribers—the destination site cannot tell your automated traffic apart from a human scrolling on their handset. Proxy4G operates these across 18 countries and 43 carriers, including AT&T, T-Mobile and Verizon in the US, Free Mobile, SFR, Orange and Bouygues in France, and Jio 5G in India.
How does a mobile proxy actually work?
The mechanism rests on two layers: a real radio connection and a shared address pool. A physical device—a phone or 4G/5G dongle—establishes a normal data session with a carrier such as Three, EE, O2 or Movistar. The carrier hands that device an IP from its own range. Crucially, mobile networks do not assign one public IP per subscriber. They use Carrier-Grade NAT (CGNAT), defined in RFC 6598, where hundreds or thousands of real subscribers sit behind a single public IPv4 address.
When you connect to a Proxy4G endpoint at HOST:PORT, your traffic enters that device, exits onto the live cellular network, and reaches the target wearing a carrier IP shared with genuine humans. Blocking that IP risks blocking real paying customers, so platforms treat it as high-trust. For a deeper walkthrough, see how mobile proxies work.

Why does a mobile proxy beat datacenter and residential?
Proxies fall into three families, and the difference is reputation. Datacenter proxies originate from hosting providers; their IP ranges are published and easy to fingerprint, so they get blocked fastest. Residential proxies use IPs assigned to home broadband lines—cleaner, but often sourced through opaque peer networks and still one-IP-per-household, making heavy automation conspicuous.
Mobile proxies sit at the top. CGNAT means a single mobile IP fronts a crowd of real users, so it is statistically expensive for any site to ban. Carriers also re-pool IPs naturally, refreshing reputation over time. That is why Proxy4G IPs report a 100% trust score on the platforms that grade them. For the full side-by-side, read mobile vs residential vs datacenter proxies.
Mobile vs residential vs datacenter: quick comparison
| Property | Mobile (4G/5G) | Residential | Datacenter |
|---|---|---|---|
| Source of IP | Real carrier via physical SIM | Home ISP line | Hosting provider |
| CGNAT shielding | Yes — many users per IP | No — one per household | No |
| Trust / detectability | Highest trust | Medium | Lowest — easy to flag |
| Survives strict anti-bot | Yes | Often | Rarely |
| Native IP rotation | Yes — carrier re-pools | Varies | No |
| Typical cost | Higher | Medium | Lowest |
Mobile proxies trade a higher price for the cleanest, hardest-to-block reputation.
What protocols and rotation does a mobile proxy support?
Proxy4G speaks SOCKS5 as well as HTTP and HTTPS on every plan, so the same port works for browsers, scrapers, antidetect tools and apps. Authenticate by username/password or lock the port to your server with IP whitelisting; pick whichever suits your stack—see SOCKS5 vs HTTP if you are unsure.
Rotation depends on the plan. A dedicated proxy gives you an exclusive port and lets you rotate the IP on demand—instantly via the dashboard or a reset link—or automatically on a timer from 1 to 60 minutes. A shared proxy is the budget tier, auto-rotating every 5 minutes. Both run on real 4G/5G carrier IPs. Compare them in rotating vs dedicated.
What are mobile proxies used for?
- Social media multi-accounting — run many profiles without triggering linked-account bans
- Account creation — register on platforms that block datacenter ranges on sight
- Web scraping — collect data at scale behind high-trust carrier IPs
- Ad verification — see ads as a real mobile user in a target country
- SERP rank tracking — check localized rankings from genuine mobile networks
- AI agents & automation — give autonomous agents a clean, geo-targeted exit
- Sneaker bots — high-trust IPs for limited-release purchasing
How do I test a mobile proxy?
# Confirm your exit IP is a carrier address
curl -x http://USER:PASS@HOST:PORT https://api.ipify.org
# Same endpoint over SOCKS5
curl --socks5 USER:PASS@HOST:PORT https://api.ipify.org
# Trigger an on-demand rotation (dedicated plans), then re-check
curl https://RESET-LINK
curl -x http://USER:PASS@HOST:PORT https://api.ipify.orgHow to buy a mobile proxy on Proxy4G

Frequently Asked Questions
It is a gateway that sends your traffic through a real phone or 4G/5G modem with a physical SIM card. The website you reach sees the mobile carrier's IP address, not yours. Because mobile networks share each public IP among many real subscribers via CGNAT, the address looks like an ordinary human on a phone, which makes it far harder to detect or block than a datacenter IP.
Mobile carriers route hundreds or thousands of genuine subscribers behind one public IP using Carrier-Grade NAT (RFC 6598). Banning that IP would also block real paying customers, so platforms hesitate to do it. Carriers also rotate and re-pool addresses naturally, refreshing their reputation. That combination is why Proxy4G mobile IPs report a 100% trust score where datacenter ranges are flagged on sight.
Every plan supports HTTP, HTTPS and SOCKS5 on the same port, so the proxy works with browsers, scrapers, mobile apps and antidetect tools. You can authenticate with a username and password or whitelist your server's IP. Your host, port and credentials are emailed within minutes of payment — you point your tool at HOST:PORT and connect.
Dedicated mobile proxies start at $27/month with an exclusive port and on-demand IP rotation. Shared proxies start at $10.80/month with automatic rotation every five minutes. Terms run 1, 3, 6 or 12 months, and longer durations lower the effective monthly rate. Full per-country pricing is on the /pricing/ page; you pay in BTC, ETH, SOL or USDT.
No. Proxy4G is no-KYC: there is no government ID, no name or address, no phone number, and no email or card verification. Your account is created automatically on your first order, and payment is cryptocurrency only — Bitcoin, Ethereum, Solana, USDT or your wallet balance. We also do not log your destination traffic.
