# Mobile proxy

> A proxy exiting through a mobile carrier address, shared by many real handsets via carrier-grade NAT.

**A mobile proxy routes traffic through an address assigned by a mobile network operator** — the same kind of address a phone on 4G or 5G uses.

## Why they are the hardest to block

Mobile networks place large numbers of subscribers behind a small number of public addresses using carrier-grade NAT. A single mobile address may represent hundreds or thousands of genuine users at once. Blocking it means blocking all of them, so filtering systems are markedly more tolerant of mobile ranges.

## The cost of that tolerance

- The most expensive category, by a wide margin.

- Higher and more variable latency than any other type.

- Addresses rotate on the carrier’s schedule, not necessarily yours.

- Smaller pools, since each address is a real SIM on a real network.

## When it is worth it

Mobile-only surfaces, and targets whose [anti-bot systems](/glossary/anti-bot-system/) have defeated every cheaper category. It is a last resort by design, not a default.
