Most "mobile" proxy services on the market resell IP pools they don't control, which leaves operators guessing about freshness and trust. Proxies.sx takes the opposite approach: it runs its own 4G/5G infrastructure on real carrier SIM cards and a proprietary SDK device network, with no third-party reselling.
How the infrastructure works
Proxies.sx operates two independent pools instead of buying access to someone else's network. Both are owned and monitored by the team, and unstable IPs are pulled from rotation automatically.
| Pool | Includes | Used for |
|---|---|---|
| Premium modem pool | Proprietary 4G/5G modems with real carrier SIM cards | Important accounts, stable sessions, commercial tasks |
| Device network | Proprietary SDK network of partner devices | Large-scale scraping, rare geos, broad country coverage |
The result is "live" carrier IPs with a high trust score, refreshed with new addresses almost daily across 70+ countries.
What sets it apart
Because the network is owned end to end, IP quality and geography stay consistent rather than degrading as pools change hands.
- Real 4G/5G carrier IPs, not datacenter ranges disguised as mobile
- Two independent device pools for stability and broad coverage
- Fresh IPs added daily, a high trust score, and fewer CAPTCHAs
- Flexible rotation, sticky sessions, and city / carrier / ASN / ISP targeting
- HTTP and SOCKS5, REST API, and MCP for automation and AI systems
Where it fits
The mix of high-trust mobile IPs and granular targeting covers most operational workloads:
- Web scraping and data collection — fewer blocks and CAPTCHAs
- Account management — stable sessions and high IP trust
- Affiliate marketing — work across countries, cities, and carriers
- SEO and ad monitoring — real mobile results without datacenter footprints
- Automation and AI systems — API, MCP, and automated routing
Pricing and payments
There are no time-based fees, slot rentals, or hidden subscriptions — billing is strictly per consumed traffic, with a low minimum top-up. Shared and private 4G/5G proxies draw from a single balance.
| Payment method | Supported |
|---|---|
| Bank cards | Visa, Mastercard, American Express |
| CoinGate | BTC, ETH, USDT, USDC, and 200+ cryptocurrencies |
| USDT / TRON | Direct crypto transfers |
| x402 | Micropayments for AI systems |
Conclusion
For operators who care about IP provenance, Proxies.sx removes the reseller layer: owned 4G/5G infrastructure, traffic-only billing, and tooling built for automation. Teams running multi-account or anti-detect setups can pair it with a browser like ExitAnty to keep sessions isolated end to end.

FAQ
- Are these real mobile IPs?
- Yes. The network runs on physical modems with carrier SIM cards plus a large pool of real mobile devices, rather than datacenter ranges relabeled as mobile.
- How many countries are covered?
- More than 70. The premium modem pool covers 30+ popular geos, while the device network reaches rarer regions in Latin America, Africa, and Asia.
- How does billing work?
- You pay only for consumed traffic — no time-based fees or slot rentals. One shared balance works across shared and private proxies.
- Is the device network reselling third-party proxies?
- No. Devices connect directly to Proxies.sx infrastructure through the company's own SDK, integrated by partners.
- Is there an API?
- Yes. The REST API manages proxies, rotation, countries, carriers, and balance, and MCP is supported for AI systems and automation.
