Set up our 4G mobile proxies in 5 minutes

1. Get your credentials

After signing up at app.proxyserver.tech/login, your account dashboard shows:

• Endpoint host — e.g. proxy.proxyserver.tech
• Port — HTTP, HTTPS, and SOCKS5 ports for each modem
• Username & password — auto-generated, rotatable from the dashboard
• IP whitelist (optional) — bind a proxy to specific source IPs

2. Test the connection

The fastest sanity check — see your assigned 4G IP:

curl -x http://USER:[email protected]:10001 https://api.ipify.org

Expected output: a real Telcel/AT&T/Movistar IP from the country you selected.

3. Rotate the IP

Each modem has a unique rotation URL. A GET request triggers a new 4G IP within 8-15 seconds (no manual SIM swap):

curl https://api.proxyserver.tech/rotate/MODEM_ID?token=YOUR_TOKEN

You can rotate manually, on a schedule, or per-request. There's no rotation cap.

Use it from your favourite tool

Python (requests)

import requests
proxies = {
  'http':  'http://USER:[email protected]:10001',
  'https': 'http://USER:[email protected]:10001',
}
r = requests.get('https://example.com', proxies=proxies, timeout=30)
print(r.status_code, r.text[:200])

Node.js (axios + https-proxy-agent)

import axios from 'axios';
import { HttpsProxyAgent } from 'https-proxy-agent';
const agent = new HttpsProxyAgent('http://USER:[email protected]:10001');
const res = await axios.get('https://example.com', { httpsAgent: agent });
console.log(res.status);

Puppeteer / Playwright

// Puppeteer
const browser = await puppeteer.launch({
  args: ['--proxy-server=proxy.proxyserver.tech:10001']
});
const page = await browser.newPage();
await page.authenticate({ username: 'USER', password: 'PASS' });

// Playwright
const browser = await chromium.launch({
  proxy: { server: 'http://proxy.proxyserver.tech:10001', username: 'USER', password: 'PASS' }
});

Browser (manual)

Most browsers don't accept proxy auth in the URL. Use FoxyProxy or Proxy SwitchyOmega to add the host, port, user, and password.

Scrapy

# settings.py
DOWNLOADER_MIDDLEWARES = {
  'scrapy.downloadermiddlewares.httpproxy.HttpProxyMiddleware': 110,
}
# in your spider
def start_requests(self):
  yield scrapy.Request('https://example.com',
    meta={'proxy': 'http://USER:[email protected]:10001'})

SOCKS5 vs HTTP

Each modem exposes both. Use SOCKS5 when you need raw TCP (gRPC, custom protocols, leaky-bucket DNS). Use HTTP when your stack only speaks HTTP proxies.

Sticky session?

Don't rotate. The same IP stays bound to the modem until you call the rotation URL or the carrier itself drops the session. Most modems hold the same IP for hours.

Common gotchas

• 403 from the target — you forgot to authenticate. Check the user/pass in the proxy URL.
• Connection refused — the modem is rebooting after a forced rotation. Retry in 15s.
• Wrong country — your account has both Mexico and Spain pools. Specify the right port.
• Slow on first request — 4G modems wake from idle. Subsequent requests are sub-100ms.
