Why 4G Proxies?
Mobile proxies utilize IP addresses assigned by mobile carriers (like Verizon, T-Mobile, SFR) to real users' devices. This makes them extremely difficult for websites to block because banning one IP might inadvertently ban thousands of legitimate mobile users behind the same CGNAT.
The Trust Factor
Websites assign trust scores to different types of IPs. Datecenter IPs (like AWS or DigitalOcean) have very low inherent trust. Residential IPs are better, but Mobile 4G/5G IPs are the gold standard because they are indistinguishable from real human traffic on a phone.
Key Benefits
- High Anonymity: Carrier-grade NAT (CGNAT) naturally masks user activity.
- IP Rotation: Mobile IPs rotate frequently, providing a fresh identity for each session or period.
- Bypass Captchas: Higher trust scores lead to significantly fewer CAPTCHAs and security checks.
Conclusion
For serious scraping or account management, investing in high-quality 4G mobile proxies is often the most cost-effective solution despite higher per-GB costs, due to the massive savings in engineering time fighting blocks.
