# Mobile proxy

A mobile proxy routes traffic through an IP address that a cellular carrier assigned to a real 4G or 5G device. Carriers place thousands of subscribers behind each address with carrier-grade NAT, so blocking a mobile IP means blocking real customers; websites therefore treat mobile addresses with more tolerance than any other kind. Mobile proxies are sold as a rotating pool billed per gigabyte or as a dedicated device rented per term.


## Why mobile IPs are trusted

With [CGNAT](https://proxshift.com/glossary/cgnat), a single public IPv4 address represents a whole cell of phones. Reputation systems cannot punish one address without hurting many legitimate users, and mobile-first platforms expect most of their traffic to arrive from exactly these ranges. That is the "trust ceiling" mobile proxies buy.


## Rotating pool versus dedicated device

|  | Rotating pool | Dedicated device |
| --- | --- | --- |
| What you get | A new carrier IP per connection, or a sticky session | One physical modem and its IP, yours alone |
| Rotation | Automatic | On demand by link or API, or on a timer |
| Billing | Per GB, one rate worldwide | Per device and term, unlimited traffic, priced by country |
| Best for | Collection at scale on mobile-first targets | Accounts and apps that must look like one consistent phone |


## Speed

Mobile exits run at cellular speed: fine for pages, apps and most collection jobs, below a wired link for bulk transfer. For raw throughput, ISP or datacenter proxies are the better fit.


## How it works at ProxShift

ProxShift mobile proxies draw on a rotating pool of 4.9M+ carrier IPs in 100+ countries from mob.proxshift.com (ports 9000 and 9001, same username parameters as residential) from $2.62 per GB, and dedicated 4G/5G devices in 20 countries from $31.05 a month on a 90-day term, with rotation on demand or on a timer.

## Questions

**Do I need mobile proxies for social platforms?**

Not always. Many accounts run well on ISP addresses in the account's country. Mobile becomes the answer when a platform challenges residential-grade addresses, when the audience is mobile-first, or when an account deserves its own device.

**How does rotation work on a dedicated device?**

You trigger it: a signed link or an API call asks the carrier for a new address, or a timer rotates every N minutes. The device keeps the same carrier and country.
