Get a new carrier IP on a dedicated T-Mobile, AT&T or Verizon 4G/5G port by link, API call or timer, check the result, and pick a rotation rhythm.

**Quick answer — How do I rotate a mobile proxy IP?**

To rotate a mobile proxy IP, make its 4G/5G modem reconnect to the carrier. Open the port's rotation link, call it from a script, or set a timer. **FiftyStateProxy**'s dedicated T-Mobile, AT&T and Verizon ports start at $3.75 a day, as of October 2026. Each port accepts one rotation every 30 seconds at most. No KYC — no ID, no selfie, no documents. Pay in crypto.

## Mobile IP rotation in short

| Attribute | Value |
| --- | --- |
| Ways to rotate | Rotation link, API call or automatic timer |
| Rotation rules | New IP on demand by rotation link or API call, at most once every 30 seconds. On 7-day and 30-day ports, you can also set an automatic rotation timer, from every 2 minutes to every 24 hours. Otherwise your port keeps its IP until you rotate it, although the carrier can change it on its own from time to time |
| Time per rotation | Each rotation reconnects your port to the carrier and usually takes 5–15 seconds; the carrier may occasionally hand back the same IP: just rotate again |
| Rotation link | `https://fiftystateproxy.com/api/v1/mobile/{port}/rotate?key=API_KEY` |
| Too-soon reply | HTTP 429 with a `Retry-After` header in seconds |
| US carriers | T-Mobile, AT&T and Verizon |
| Port prices | $3.75 for 1 day · $15 for 7 days · $45 for 30 days |
| KYC and payment | No KYC — no ID, no selfie, no documents. Pay in crypto. |

## How do I rotate the IP step by step?

Seven steps, from renting a port to an automatic timer.

1. **Rent a dedicated port** — Choose a carrier port (T-Mobile, AT&T or Verizon) on the page about how much a US mobile proxy costs. The checkout lists the carriers in stock.
2. **Create an API key** — In the dashboard, create an API key for your proxies. You can revoke a key at any time.
3. **Fill in the rotation link** — Start from https://fiftystateproxy.com/api/v1/mobile/{port}/rotate?key=API_KEY. Swap {port} for the ID shown on your port's page, and API_KEY for the key you just created.
4. **Call the link** — Open it in a browser, save it as a bookmark, or call it from curl or a script.
5. **Wait for the reconnect** — Each rotation reconnects your port to the carrier and usually takes 5–15 seconds; the carrier may occasionally hand back the same IP: just rotate again.
6. **Check the new IP** — Through the port, call https://api.ipify.org?format=json; the IP it returns should differ from the last one.
7. **Set a timer if you need one** — On 7-day and 30-day ports, choose an automatic interval in the dashboard.

## What happens when a mobile proxy IP rotates?

When a mobile proxy IP rotates, the modem drops its data session and attaches to the carrier network again. The carrier then hands the port a public address from its pool.

**Rotating a mobile proxy IP means reconnecting its 4G/5G modem to the carrier, which then assigns the port a new public address from its pool.**

Carriers run carrier-grade NAT, using the 100.64.0.0/10 block that RFC 6598 set aside for the subscriber side. Many subscribers share each public address. The carrier, not you, decides which address comes next. A rotation keeps the same modem, SIM and carrier; only the public IP changes. The basics are in [what a mobile proxy is](https://fiftystateproxy.com/what-is-a-mobile-proxy/ "Mobile proxies, CGNAT and carrier IPs explained").

## How do I change the IP with the rotation link or the API?

You rotate by sending a GET request to your port's link, `https://fiftystateproxy.com/api/v1/mobile/{port}/rotate?key=API_KEY`, with your port ID and API key filled in. The JSON reply holds the new IP (`ip`), the previous one (`previousIp`) and the next allowed time (`nextRotationAvailableAt`). A call made too soon gets HTTP 429 and a `Retry-After` header.

**One rotation every 30 seconds means up to 120 rotation calls an hour on a single port.** Treat the link like a password: anyone who holds it can rotate your port.

*curl: rotate, then check the exit IP*

```bash
# Rotate port PORT and print the JSON reply:
# new IP, previous IP and the next time a rotation is allowed
curl -s "https://fiftystateproxy.com/api/v1/mobile/PORT/rotate?key=API_KEY"

# Check the exit IP through the port
# (HOST, PROXY_PORT, USERNAME and PASSWORD come from the port in your dashboard)
curl -x http://USERNAME:PASSWORD@HOST:PROXY_PORT "https://api.ipify.org?format=json"
```

*Python: rotate, wait, compare*

```python
# pip install requests
import time
import requests

ROTATE_URL = "https://fiftystateproxy.com/api/v1/mobile/PORT/rotate?key=API_KEY"
PROXY = "http://USERNAME:PASSWORD@HOST:PROXY_PORT"  # values from your port's page

def exit_ip():
    r = requests.get("https://api.ipify.org?format=json",
                     proxies={"http": PROXY, "https": PROXY}, timeout=30)
    return r.json()["ip"]

before = exit_ip()
resp = requests.get(ROTATE_URL, timeout=60)
if resp.status_code == 429:
    wait = int(resp.headers.get("Retry-After", "30"))
    print(f"Too soon: wait {wait} s before the next rotation")
else:
    resp.raise_for_status()
    time.sleep(15)  # the reconnect usually takes 5-15 s
    after = exit_ip()
    print(before, "->", after)
    if after == before:
        print("The carrier returned the same IP: rotate again after 30 s")
```

## How do I set an automatic rotation timer?

You set the timer in the dashboard. On 7-day and 30-day ports, FiftyStateProxy rotates the IP for you every 2 minutes to every 24 hours, as you choose. **At the 2-minute setting, a port changes IP up to 720 times a day; at the 24-hour setting, once.** One-day ports rotate by link or API only. Without a timer, the port keeps its IP until you rotate it, although the carrier occasionally reassigns the address by itself.

## Sticky or rotating: how often should I change the mobile IP?

Change the IP between independent tasks, never in the middle of one. A login, a checkout test or an account session expects one IP from start to finish.

- **One stable IP per account:** agencies that manage client accounts keep the port's IP for the whole session and follow each platform's rules. See [the best US proxies for social media management](https://fiftystateproxy.com/best-us-proxies-for-social-media-management/ "Best US proxies for managing client social media accounts").
- **Fresh IP per batch:** ad checks and price checks rotate between batches of pages. See [which US proxies suit ad verification](https://fiftystateproxy.com/best-us-proxies-for-ad-verification/ "Best US proxies for ad verification and geo-testing").
- **Steady monitoring:** a timer of 30 to 60 minutes spreads requests over several carrier IPs.

Pacing matters as much as rotation: Cloudflare found CGNAT addresses are rate-limited about three times as often as other addresses. Rotating mobile traffic billed per GB works differently. It draws from a shared pool, per connection or with sticky sessions, from $1.50/GB. The rotation link and the timer belong to dedicated ports, listed with both mobile products on [US mobile proxies on T-Mobile, AT&T and Verizon](https://fiftystateproxy.com/us-mobile-proxies/ "US 4G/5G mobile proxies with dedicated carrier ports").

## Why did I get the same IP after rotating?

You got the same IP because the carrier picked it again from its pool; the rotation itself worked. Carriers assign addresses from shared pools, and a recent address can come back. Wait out the 30-second limit and rotate again. If the IP stays the same across several tries, write to support with your port ID and the times of your calls.

## Rotating a mobile proxy IP: frequently asked questions

### How often can I rotate a FiftyStateProxy mobile proxy IP?

Once every 30 seconds at most, by link or API. On 7-day and 30-day ports, a timer can also rotate the IP every 2 minutes to every 24 hours.

### Does the mobile IP change if I do nothing?

Not on a schedule: the port keeps its IP until you rotate it or a timer fires. The carrier also reassigns the address now and then, so plan for an occasional change.

### Does a rotation change the carrier?

No. A rotation reconnects the same modem with the same SIM, so the carrier stays the same. Only the public IP changes.

### Is there a rotation timer on 1-day ports?

No. The automatic timer comes with 7-day and 30-day ports. A 1-day port at $3.75 rotates by link or API.

### What does HTTP 429 mean on the rotation link?

It means the last rotation was less than 30 seconds ago. Read the `Retry-After` header, wait that many seconds and call the link again.

### Do I need ID to rent a US mobile port from FiftyStateProxy?

No. FiftyStateProxy asks for no ID, no selfie and no documents. You pay in BTC, USDT, USDC, ETH, SOL, LTC, XMR.
