Web scraping at scale fails for one reason: the target recognizes your traffic as non-human and blocks the IP. Datacenter IPs live in published ASN ranges that anti-bot systems flag on sight; a 4G mobile proxy presents a residential-grade carrier IP shared by hundreds or thousands of real subscribers behind CGNAT (RFC 6598), so blocking it risks collateral damage to legitimate mobile users. That asymmetry is the whole game — and it's why Proxy4G's pool of real SIM cards on AT&T, Verizon, Orange, Vodafone, Three and 38 other carriers reaches a 100% trust score on every plan.
Why do mobile IPs beat datacenter on scraping success rate?
Anti-bot platforms grade every incoming IP. The fastest, cheapest classifier is ASN reputation: an IP belonging to AWS, Hetzner, OVH or any hosting provider is presumed automated and served a CAPTCHA, a 403, or fabricated data. Datacenter proxies fail here before your crawler sends a single header.
Mobile carrier IPs invert the math. Because CGNAT packs many real phones behind each public address, a target site cannot ban the IP without also banning paying customers on that carrier — so mobile ranges carry the highest default trust. Proxy4G runs on real devices with physical SIM cards, not emulated or datacenter-laundered ranges, so the IP your scraper presents is indistinguishable from a phone browsing on 4G/LTE/5G. Combined with a clean per-IP request rate, that pushes success rates on hardened targets far above what any datacenter pool achieves.
The pool behind your crawler
Rotating or sticky: which mode for which scrape?
Two scraping patterns need two rotation strategies, and Proxy4G covers both.
Rotating (high-volume crawling). When you're harvesting thousands of independent pages — product catalogs, listings, search results — you want a fresh IP often so no single address accumulates a suspicious request count. The Shared plan auto-rotates its IP every 5 minutes; on a Dedicated port you can set auto-rotation anywhere from 1 to 60 minutes or trigger an instant rotation from the dashboard or a reset link.
Sticky (session-bound scraping). Some targets require you to hold one IP across a multi-step flow — logging in, paginating behind a session cookie, or scraping account-gated data. Here a Dedicated proxy on a long rotation interval (or manual rotation only) keeps the same carrier IP for the whole session, so the site sees a single coherent visitor instead of an IP that teleports mid-flow. See rotating vs dedicated proxies for the full trade-off.
Proxy types for scraping, compared
| Proxy type | Anti-bot trust | Best for |
|---|---|---|
| 4G/5G mobile (Proxy4G) | Highest — carrier IP behind CGNAT | Hardened targets, social, SERP, account flows |
| Residential | High | General scraping, geo-content |
| Datacenter | Low — flagged by ASN | Unprotected APIs, internal tools |
| Free/public proxies | None — pre-banned, unsafe | Nothing production-grade |

Web scraping with Python (requests)
import requests
# Credentials are emailed within minutes of payment.
# Use HTTP/HTTPS or swap to socks5:// for SOCKS5.
proxies = {
"http": "http://USER:PASS@HOST:PORT",
"https": "http://USER:PASS@HOST:PORT",
}
resp = requests.get(
"https://example.com/listings",
proxies=proxies,
headers={"User-Agent": "Mozilla/5.0 (Linux; Android 14) AppleWebKit/537.36"},
timeout=30,
)
print(resp.status_code, resp.headers.get("x-served-from"))
# Force a fresh carrier IP between batches (Dedicated reset link):
# requests.get("https://YOUR-RESET-LINK")Scraping best practices that keep success rates high
- Match rotation to the job — rotate per-request-batch for crawling, hold a sticky Dedicated IP for session/login flows.
- Send a realistic mobile User-Agent and full header set; a carrier IP with a Python-default UA still looks automated.
- Throttle per-IP request rate and add jitter — a clean IP firing 50 requests/second is still obvious.
- Respect each site's robots.txt and terms; scrape public data and avoid logged-in scraping you're not authorized for.
- Reuse cookies/sessions on a sticky IP rather than re-authenticating on every request.
- Whitelist your server's IP or use user/pass auth — both are supported, no plaintext credentials in shared scripts.
- Handle 429/403 with backoff and an IP rotation rather than hammering through a block.
From scraping to autonomous and SERP workloads
Web scraping rarely runs alone. If your crawler feeds an LLM pipeline or runs unattended, the same carrier IPs power AI agents and automation — and autonomous agents can even self-fund and buy access over the x402 protocol without a human in the loop. If you're specifically harvesting Google results, SERP and rank tracking demands frequent rotation and clean mobile IPs to avoid the CAPTCHA wall that datacenter scrapers hit instantly.
Every plan is no-KYC — no ID, name, phone or email verification, account auto-created on first order — and paid in crypto (BTC, ETH, SOL, USDT). Dedicated starts at $27/mo, Shared at $10.80/mo; credentials land in your inbox minutes after payment. Browse locations or jump to pricing for per-country rates.
Frequently Asked Questions
For targets with anti-bot protection — social platforms, marketplaces, search engines — 4G/5G mobile proxies on real carrier IPs deliver the highest success rate because they share the trust score of millions of real phones behind CGNAT and can't be banned without affecting legitimate subscribers. Datacenter proxies are cheaper but get flagged by ASN reputation. For unprotected internal APIs, datacenter may suffice; for anything hardened, mobile wins.
Use rotating IPs for high-volume crawling of independent pages so no single IP accumulates a suspicious request count — Proxy4G's Shared plan rotates every 5 minutes, Dedicated rotates on a 1–60 minute timer or on demand. Use a sticky (long-rotation Dedicated) IP for session-bound work like logins, multi-step pagination, or cart flows, where the target must see one coherent visitor across requests.
Far less often than datacenter IPs. Because every Proxy4G IP is a genuine carrier address behind CGNAT, blocking it would also block real mobile customers on that carrier, so anti-bot systems treat it with the highest default trust (100% trust score). Blocks still happen if you scrape carelessly — fix that with proper rotation, realistic headers, rate throttling, and backoff on 429/403 responses.
Yes. Every plan supports HTTP, HTTPS, and SOCKS5, with username/password or IP-whitelist authentication. SOCKS5 is useful when you need DNS resolution to happen at the proxy or you're tunneling non-HTTP traffic. In Python's requests library, set both proxy keys to socks5://USER:PASS@HOST:PORT and install the requests[socks] extra. Connection details are emailed within minutes of payment.
Scraping publicly available data is generally lawful in many jurisdictions, but legality depends on what you scrape, where, and a site's terms of service — scraping personal data or bypassing authentication you're not authorized for carries risk. Proxy4G provides the network infrastructure; you're responsible for lawful, terms-respecting use. See our guide on whether mobile proxies are legal for the broader picture.
Payment is cryptocurrency only — Bitcoin, Ethereum, Solana, or USDT, plus a wallet top-up — with no cards or PayPal and no KYC. Your account is auto-created on first order with no ID, name, or email verification required. Connection credentials (host, port, username, password) arrive by email within minutes of payment, so you can wire them into your crawler the same session.
