Mobile Proxy

A mobile proxy exits through an IP assigned by a cellular carrier — the kind of address a phone gets on 4G or 5G. Its ASN belongs to a mobile operator, and crucially many subscribers share each address behind carrier-grade NAT. Because blocking one mobile IP could cut off thousands of legitimate users, sites are reluctant to ban them, giving mobile proxies a low fraud score. The cost is high price and variable speed, and, as with residential, provenance matters.

Traffic leaves through a carrier IP shared via CGNAT, so your requests mingle with real mobile users. Carriers rotate these addresses, and their shared nature is exactly what makes them trusted — the collateral damage of blocking deters sites from doing so. Mobile proxies suit tasks that demand the highest apparent legitimacy against aggressive anti-bot systems. They are the most expensive proxy type and their throughput depends on the underlying cellular link, so they are overkill for routine work that tolerates a datacenter IP.

s4m offers authenticated datacenter proxies rather than mobile proxies. For most scraping, monitoring, testing and privacy tasks a fast, affordable datacenter exit is the right tool, and s4m is transparent that its IPs are datacenter. If a specific target only tolerates mobile IPs, that narrow case is outside s4m's offering. For a clean, stable exit you alone control, add an s4m dedicated IP, and try the free public list before buying proxy plans.
