How to Rotate the IP on a US 4G/5G Mobile Proxy

How does IP rotation work on a dedicated mobile port?

A rotation tells the modem behind your port to drop its mobile data connection and reconnect. The carrier then assigns an address from its own pool, which is usually a new one. During the reconnection, requests through the port fail or wait, so pause your traffic. The port, username and password stay the same; only the exit IP changes.

Carriers share public IPv4 addresses between many phones through carrier-grade NAT (CGNAT). The new IP may therefore also carry traffic from ordinary phone users on that network. Your modem itself is never shared: Unlimited data on a dedicated port (fair use: one customer per modem, no resale).

How do I rotate the IP with a link or API call?

Send one GET request to your port's rotation URL: https://statesideip.com/api/v1/mobile/{port}/rotate?key=API_KEY. Replace {port} with your port number and API_KEY with the key from your dashboard. Keep the key private, because anyone with the full link can rotate your port.

# Values from your dashboard
PORT="YOUR_PORT"
KEY="API_KEY"

# Build the rotation URL from the documented format
URL=$(printf '%s' "https://statesideip.com/api/v1/mobile/{port}/rotate?key=API_KEY" | sed -e "s/{port}/$PORT/" -e "s/API_KEY/$KEY/")

# 1) Ask the modem for a new IP (direct call, not through the proxy)
curl -s "$URL"

# 2) After the reconnection, print the exit IP through the port
curl -s -x "http://USERNAME:[email protected]:$PORT" \
  "https://api.ipify.org?format=json"

import time
import requests

HOST = "gw.statesideip.com"   # use the host shown for your port
PORT = "YOUR_PORT"                # dedicated port number from the dashboard
KEY = "API_KEY"                   # API key from the dashboard
PROXY = f"http://USERNAME:PASSWORD@{HOST}:{PORT}"
PROXIES = {"http": PROXY, "https": PROXY}
ROTATE_URL = "https://statesideip.com/api/v1/mobile/{port}/rotate?key=API_KEY".replace("{port}", PORT).replace("API_KEY", KEY)


def current_ip():
    r = requests.get("https://api.ipify.org?format=json", proxies=PROXIES, timeout=15)
    return r.json()["ip"]


def rotate(max_wait=90):
    old_ip = current_ip()
    requests.get(ROTATE_URL, timeout=15)   # direct call, not through the proxy
    deadline = time.time() + max_wait      # limit for this script, not a promised time
    while time.time() < deadline:
        time.sleep(5)
        try:
            new_ip = current_ip()
        except requests.RequestException:
            continue                       # modem still reconnecting
        if new_ip != old_ip:
            return old_ip, new_ip
    raise TimeoutError("IP did not change: rotate again or check the port")


print(rotate())

How do I rotate the IP automatically on a timer?

Set a rotation timer on a 7-day or 30-day port, and the IP changes on schedule with no code. New IP on demand through a rotation link or API call, or automatically on a timer you set (minimum 2 minutes). Choose the interval from the job. Account work for a client brand needs a long interval, while checks across many IPs can use a shorter one. A rotation in the middle of a request breaks it, so add retries or use the API instead.

How do I check that the IP really changed?

Request an IP-echo service through the port before and after the rotation, and compare the two addresses. https://api.ipify.org?format=json returns only your exit IP, as JSON. Carriers sometimes hand back the same address, so rotate again if it did not change.

You can also look up the network of any IP in RIPEstat. For reference, T-Mobile USA announces AS21928, AT&T Mobility AS20057, and Verizon (Cellco) AS22394 and AS6167.

How long should I wait after a rotation?

Wait until an IP check through the port succeeds with a new address, not for a fixed delay. Reconnection time depends on the carrier, the signal at the modem and network load. For that reason, StatesideIP does not promise a fixed number of seconds. Poll every few seconds with a time limit, as the Python example does, and pause your job until the check passes.

Which carrier should I pick for rotation?

Pick the carrier your audience uses; rotation works the same way on all three US carriers. Network test results differ, as of October 2026:

• T-Mobile: 12 Opensignal awards in its January 2026 report. Ookla named it the best and fastest US mobile network for H1 2026. T-Mobile US runs an IPv6-only network using 464XLAT.
• Verizon: 3 Opensignal awards, including 5G Video. Ookla named it the best network for coverage.
• AT&T: 1 Opensignal award, and the highest time on network at 99.6%.
