The cleanest mobile and residential IPs on the internet.
Real 4G/5G mobile and residential proxies for automation, account management and data collection at any scale. A proprietary modem pool plus a partner device network, fresh IPs every day, and you pay only for the traffic you use.
What they do
Proxies.sx provides real 4G/5G carrier IPs on infrastructure it owns. Unlike most of the market, there is no resold third-party traffic: the entire network belongs to the Proxies.sx team, and new IPs are added to it every day.
Two proprietary sources make this 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 work. The second is a partner device network in 100+ countries that covers both mobile and standard residential connections (home and office internet), not just SIM traffic. It is what makes large-scale data collection, rare geos and broad country coverage possible.
Spin up dedicated ports through the dashboard or API, set up rotation however you need, and use sticky sessions and automatic routing for the task at hand. Everything runs over HTTP, SOCKS5 and a full REST API, and it is built with AI agents in mind: an MCP server lets Claude, Cursor and Cline manage the whole setup in plain conversation, and the x402 protocol lets agents pay per request in USDC (Base or Solana) with no sign-up and no API keys, settling in about 2 seconds.

Premium modem pool
500+ proprietary 4G/5G modems with real carrier SIMs
Mobile + residential device network
A proprietary partner network of mobile and residential connections, including regular user internet

FAQ
Are these real mobile IPs?
Yes. They are genuine 4G/5G carrier IPs, not a datacenter posing as mobile. The network is built on a pool of 500+ physical modems with SIM cards plus a partner device network, so the IPs look more natural to platforms and carry a higher level of trust.
How does pricing work?
One simple model: you pay per GB of real 4G/5G traffic, from $4/GB down to $2.40/GB at volume. Endpoints, unlimited rotation and 24/7 support are free, and traffic never expires.
Does traffic expire?
Never. Buy once and use it whenever you like; your GB balance carries over indefinitely.
How many countries are available?
100+. The premium pool covers 30+ popular geos, including the US, UK, Germany, France, Poland, Spain, Italy, the Netherlands, Japan and Singapore. The partner network adds rare regions in Latin America, Africa and Asia. New IPs and countries appear almost every day.
Is it suitable for resellers?
Yes. Proxies.sx can power a proxy service under your own brand: API, webhook integrations, SDK and ready-made infrastructure for partners and resellers.
