How to Built a Mobile Proxy Farm?

Learn how to build your own mobile proxy farm to save costs and gain better control over your proxies. This guide provides detailed steps for building a proxy farm in two different ways. Feel free to choose the method you need for an in-depth study!

Creating your own mobile proxy farm can be an excellent way to save money and gain more control over your proxy usage. Building your own proxy farm is a viable solution if you’ve been frustrated by the high cost of mobile proxies or the frequent blocks and restrictions imposed by third-party providers.

This guide will walk you through the process, offering two main methods: building from scratch with Raspberry Pi and modems or buying a ready-made solution from Proxy-Seller.

Benefits of Building a Mobile Proxy Farm

Building your own mobile proxy farm comes with numerous benefits that can make a significant difference in how you manage and utilize proxies for various online activities. Here are some of the key advantages:

Cost Savings

Creating your own proxy farm can significantly reduce costs compared to buying proxies from third-party providers, especially if you need a large number of proxies. After the initial investment in hardware, the ongoing expenses are mainly for mobile data plans, which are more economical over time.


With your own proxy setup, you have full control over configuration and operation, allowing you to optimize performance, apply custom configurations, and avoid third-party restrictions. You can manage bandwidth, set up specific routing rules, and implement tailored security measures.


You can customize your proxy farm to meet your specific needs, including the number of proxies, types of devices, and geographic distribution of IP addresses. This flexibility lets you create a proxy network that perfectly aligns with your use cases, such as web scraping, social media management, or ad verification.


Managing your own proxies ensures they are always up and running, reducing downtime and improving reliability. You can quickly identify and resolve issues, leading to a more stable and dependable proxy service.


Building your own proxy farm allows you to easily scale the number of proxies as needed. This is particularly beneficial for businesses with fluctuating demands or specific projects requiring increased proxy usage.

Comprehensive Customization and Control

Having your own proxy farm gives you comprehensive control over setup, configuration, and maintenance. You can optimize the farm to meet specific requirements, implement advanced security protocols, manage proxy rotation schedules, and configure custom software solutions to enhance performance and functionality.

How to Built a Mobile Proxy Farm?

I will introduce two approaches to building a mobile proxy farm: starting from scratch with a Raspberry Pi and modems or purchasing a ready-made kit from Proxy-Seller. Each method comes with its own steps, benefits, and challenges.

Building from Scratch Using Raspberry Pi and Modems

Building a mobile proxy farm from scratch involves sourcing individual components and assembling them into a working system. This method requires a good understanding of hardware and software setup but offers the highest level of customization and control. Here’s a step-by-step guide to get you started:

Step 1. Gather Hardware:

Obtain Raspberry Pi units, modems with SIM cards, a USB hub, Ethernet cables, micro SD cards preloaded with Raspberry Pi OS, and necessary peripherals like a monitor and keyboard.

  • Raspberry Pi 4 or later model with at least 4GB RAM
  • MicroSD card (16GB or larger) with Raspberry Pi OS installed
  • 4G/5G USB modems with SIM cards (Huawei E3372 or similar)
  • Raspberry Pi 4 and 4G modem hardware
  • USB hub to connect multiple modems (optional)
  • Ethernet cable to connect Pi to router
  • Power supply for Raspberry Pi
  • Proxy server software like Squid, 3proxy, or  TinyProxy

Step 2: Set Up the Raspberry Pi

  • Download the latest Raspberry Pi OS from the official Raspberry Pi website.

Download the latest Raspberry Pi OS

  • Use the Raspberry Pi Imager tool to flash the downloaded OS image onto a MicroSD card. This tool simplifies the process and ensures the OS is properly installed.
  • Insert the flashed MicroSD card into the Raspberry Pi.

  • Connect the Raspberry Pi to an Ethernet cable for internet access, a USB hub to accommodate multiple USB modems, and power.

Connect the Raspberry Pi

  • Connect Raspberry Pi to a monitor and keyboard.

  • Once logged in, update the system packages by running the following commands:
sudo apt update
sudo apt upgrade

Step 3: Set Up 4G Modems

  • Insert SIM cards into each of the 4G USB modems. Ensure the SIM cards are active and have data plans.
  • Plug the modems into the USB hub connected to the Raspberry Pi.
  • Install the usb_modeswitch package to handle the modem connection
 sudo apt install usb-modeswitch
  • Verify that the modems are detected by the Raspberry Pi using the lsusb command
  • The output should list the connected modems, indicating the system recognizes them.

Step 4: Install and Configure Proxy Software

  • Install the Squid proxy server software:
sudo apt install squid
  • Edit the Squid configuration file located at /etc/squid/squid.conf:
sudo nano /etc/squid/squid.conf
  • Uncomment and modify the http_access allow line to permit access.
  • Add the following line to make Squid listen on all interfaces:
  • Save and close the file.
  • Restart the Squid service to apply the new configuration:
sudo systemctl restart squid

Step 5: Test the Mobile Proxy

  • Use the following command to find the Pi's IP address:
 hostname -I
  • Set your browser or script to use the proxy IP and port 3128. (By default, the Squid proxy server listens on port 3128)

Set your browser

  • Visit an IP checking site (such as to verify that the proxy is working and routing traffic through the 4G modems.
  • For advanced users, consider using the Huawei HiLink API to programmatically change the proxy IP address, providing additional flexibility and control.


Here are some of the challenges you need to face using this method:

  • Complexity: Requires technical knowledge of networking and Linux.
  • Time-Consuming: Initial setup and ongoing maintenance can be labor-intensive.
  • Troubleshooting: Any issues must be resolved manually, which can be challenging without sufficient technical expertise.

So you can also choose the following more relaxed way to build your mobile proxies,

Purchasing a Ready-Made Kit from Proxy-Seller
