Mobile Proxy

A mobile proxy routes traffic through real 3G/4G/5G cellular connections, using carrier-assigned IPs that are the hardest of all proxy types to detect or block.

Last updated May 28, 2026

Definition

A mobile proxy sends your traffic through a real mobile device on a cellular network, using an IP assigned by a carrier. Because mobile carriers share a limited pool of IPs across thousands of users via CGNAT, blocking a mobile IP risks blocking many legitimate people — so websites treat mobile IPs with the highest trust.

Why mobile IPs are so trusted

The shared, constantly-recycling nature of carrier IPs makes them extremely difficult to fingerprint or ban. This makes mobile proxies the top choice for the most sensitive automation, though they are typically the most expensive and bandwidth-limited option.

Examples

1

Automating social platforms that aggressively block other proxy types

2

Verifying mobile-specific ad campaigns and app experiences

Common Use Cases

Social media automation and account management
Mobile ad verification
App testing from real carrier networks
Accessing services that only trust mobile IPs

Frequently Asked Questions

Carriers share IPs among many real users through CGNAT, so blocking one mobile IP would affect many legitimate customers — websites avoid doing it.
Yes. Real cellular bandwidth is costly, so mobile proxies are usually the priciest type and are often metered by data usage.

All terms

ISP Proxy

An ISP proxy (static residential) is a datacenter-hosted IP that is registered to an Internet Service Provider, combining datacenter speed with residential-level trust.

Rotating Proxy

A rotating proxy automatically assigns a different IP address from a pool for each request or on a set interval, spreading traffic across many IPs to avoid blocks.

CGNAT (Carrier-Grade NAT)

CGNAT is a technique carriers use to share one public IP among many customers — which is exactly why mobile proxy IPs are so trusted and hard to block.

Read definition

Residential Proxy

A residential proxy routes your traffic through a real device with an IP assigned by an Internet Service Provider, so requests appear to come from a genuine home user rather than a server.
