Creating an affordable 4G proxy system from scratch is easier than you think if you're willing to use off-the-shelf hardware and smart software choices. The goal is to create a system that can switch between distinct LTE carriers so that each web request appears to come from a different IP address. This is useful for bulk content extraction, multi-profile engagement, or testing location-based services without getting banned.

Start by gathering the necessary hardware. You’ll need multiple secondhand LTE hotspots. Look for models like the TP-Link M7350. These are often sold cheaply on eBay because people trade in old units. Aim for a minimum of five routers to start. You’ll also need a a surge-protected extension cord and a reliable wired network for your control computer.

Next, acquire 4G SIM cards. Use SIMs sourced from AT&T, T-Mobile, Verizon, etc. if possible. This increases the range of available public IPs. You can buy these on AliExpress or SIMCard.com for between $2 and $5. Make sure they are pure data plans without voice or text plans to keep costs low. Load each with a small monthly data plan, which should be enough for periodic API requests.

Pair every router with an individual data plan and boot it. Configure each router to use a fixed LAN address so your host machine can reliably find and manage them. Most routers have a admin dashboard reachable via 192.168.0.1 or similar into a browser. Set a strong custom login for security.

Deploy a proxy forwarder on your central machine. Polipo is a lightweight proxy solution that can be configured to cycle through gateway IPs. Install it on a Linux machine. Configure Squid to send outbound traffic through all connected hotspots. Each router acts as a distinct internet gateway. You’ll need to set up a upstream server manifest for http://hackmd.io each router in your squid.conf.

To make rotation automatic, use a a Python-based routing daemon every few requests. You can write a simple Python script using requests and urllib to cycle through the router IPs. Or use a tool like Rotator to handle the switching. Test the setup by visiting a site like whatismyip.com and verifying the public IP refreshes reliably.

Keep an eye on data usage. Cellular carriers often impose speed caps. If you notice slowdowns or blocks, lower your crawl frequency or rotate through more devices. Avoid aggressive scraping. Wait at least five to ten seconds between requests to stay under the radar.

System care requires little effort. Reboot each router every 7 days to refresh the cellular connection. If one device fails to connect, swap in a spare unit. Keep spare SIM cards and routers on hand. You can increase capacity by integrating new LTE modems as your needs grow.

This approach offers exceptional value. You can build a 5-router network for under two hundred dollars including everything needed to start. It’s not as fast or reliable as paid proxy networks, but it’s fully yours to manage. It’s also a great learning project if you want to understand how proxies, networks, and automation interact.

Always operate within legal boundaries. Don’t scrape personal data, breach website rules, or flood servers. Use your proxy farm for compliant automation tasks where you have permission. With thoughtful configuration, your budget cellular proxy network can be a highly effective solution.
