Proxies.sx delivers real 4G/5G carrier IP addresses on infrastructure it owns outright. Unlike most of the market, nothing here is resold third-party traffic — the whole network belongs to the Proxies.sx team, and new IPs get added to it every day.

Two proprietary sources make that possible. The first is a premium pool of 500+ physical 4G/5G modems with real carrier SIM cards — built for stable sessions and serious, commercial-grade work. The second is a partner device network spanning 100+ countries that covers both mobile and residential connections, including plain home and office internet, not only SIM-based traffic. That second pool is what makes large-scale data collection, rare geographies, and broad country coverage possible.

Spin up dedicated proxy ports through the dashboard or API, set IP rotation exactly how you want it, use sticky sessions, and route traffic automatically for whatever the task needs. Everything runs over HTTP, SOCKS5, and a full REST API — and it’s built with AI agents in mind too: an MCP server lets Claude, Cursor, and Cline manage the whole setup through plain conversation, and the x402 protocol lets agents pay per request in USDC (Base or Solana) with no registration, no API keys, and settlement in about 2 seconds.

How the Infrastructure Works

No rented pools, no shared IPs with strangers — here’s what’s actually behind the network:

Pool	Includes	Used For
Premium modem pool	500+ proprietary 4G/5G modems with real carrier SIM cards	Important accounts, stable sessions, commercial tasks
Mobile & residential device network	Proprietary partner device network — mobile and residential, including regular user internet connections	Large-scale scraping, rare geographies, broad country coverage

Every device on the network is monitored continuously, and anything that starts underperforming gets pulled from rotation automatically — before it ever becomes your problem.

Built for AI Agents

Proxies.sx was built for autonomous AI systems just as much as for people:

x402 protocol — your agent pays per request in USDC (Base or Solana), no registration or API keys, settlement in ~2 seconds, minimum purchase just $0.375
MCP server — 55 tools that let Claude, Cursor, and Cline manage proxy infrastructure through plain conversation, no code required
Peer Network — run a proxy agent on your own phone, VPS, or home connection and earn USDC for every GB of bandwidth you share, with payouts straight to a Solana wallet ($5 minimum)

Data Works — Done-for-You Data

Don’t want to babysit your own scrapers? Send Proxies.sx a URL and the fields you need, and the team runs the extraction on its own 4G/5G infrastructure — anti-bot systems like DataDome, Cloudflare, and PerimeterX-class defenses become their problem, not yours. You get clean, QA-checked data delivered as CSV, JSON, or via API, on a schedule, for one flat monthly retainer.

FAQ — Popular Questions About Proxies.sx

Are these real mobile IPs?

Yes. Proxies.sx works with genuine 4G/5G carrier IPs rather than datacenter proxies disguised as mobile IPs. The network is based on a proprietary pool of 500+ physical modems with carrier SIM cards, plus a partner device network covering both mobile and residential connections — this makes IPs appear more natural to platforms and increases their trust level.

How does pricing work?

One simple model: pay per GB of real 4G/5G mobile and residential traffic, from $4/GB down to $2.40/GB at volume. Endpoints, unlimited IP rotation, and 24/7 support are all free, and bandwidth never expires.

Does bandwidth expire?

Never. Buy bandwidth once, use it whenever you like — your GB balance rolls over indefinitely.

How many countries are available?

100+ countries. The premium modem pool covers 30+ popular geo locations including the USA, UK, Germany, France, Poland, Spain, Italy, the Netherlands, Japan, and Singapore. The wider partner device network extends coverage into rarer regions across Latin America, Africa, and Asia. New IPs and countries are added almost daily.

Is Proxies.sx suitable for resellers?

Yes. Proxies.sx can power custom proxy services under your own brand, with API, webhook integrations, SDK, and ready-made infrastructure for partners and resellers.
