Proxies.sx is a mobile and residential proxy service offering real 4G/5G carrier IP addresses backed by its own infrastructure. Unlike most services on the market, the platform does not resell third-party proxies — the entire network is operated by the Proxies.sx team and continuously refreshed with new IP addresses.

The service runs on two proprietary pools. The first is a private fleet of physical 4G/5G modems equipped with carrier SIM cards. The second is its own network of mobile and residential devices connected through an SDK. This allows users to access “live” IP addresses with a high trust score, making them better suited for account management, automation, web scraping, advertising, and other tasks where stability is critical.

Proxies.sx enables users to create dedicated proxy ports through a convenient dashboard or API, configure flexible IP rotation, use sticky sessions, and automatically match IPs to specific tasks. The service supports both HTTP and SOCKS5 protocols, as well as tools for automation and AI systems.
