Proxysmart: build 4G proxies

I can help you create your own residential proxy with multiple 4G USB modems. Essentially, it is going to be your own 4G proxy farm.

You own and run the hardware – I support you!

4G LTE Mobile Proxies consist of a server box (it can be a Raspberry Pi or a Mini PC or a laptop), a USB hub, and several 4G modems, where each modem is attached to its dedicated proxy address. The proxies can be rented and used either from the Internet or from the same LAN where the server box will be placed.

The software is a command-line-based BASH script with a WebApp (see the screenshots).

Full description (README.pdf or README.html) of the software is available.

Description of the 4G proxies setup

Adding a new modem to the 4G proxy setup

  • Plug it in the USB hub
  • Add its IMEI to the database
  • Apply settings.

Properties of a 4G mobile proxy farm

  • Each modem will have its own settings and firmware. The modems are identified by their unique IMEI.
  • There is a definition of every modem, including:
    • IMEI
    • NickName (for easier referring to modems instead of IMEI)
    • Proxy HTTP & Socks5 port
    • Proxy login & password
  • Each modem can be reset or restarted individually. At the moment it is done by clicking a button or by adding Cron Jobs or by API calls.
  • The complete script includes the following functions:
    • list current statuses of all modems
    • change an IP of a modem
    • reboot a modem
    • run speed test on a modem
    • reset & regenerate all configurations
    • read\send SMS or USSD
    • checking bandwidth stats
    • checking IP rotation history
  • Proxy ports can be forwarded through a VPS in the cloud.
  • OS TCP Fingerprint spoofing is supported, to simulate other Operating System TCP Fingerprints, e.g. pretending it is Windows, MacOS X, IOS, Android.
  • IPv6 is supported.


  • Consult with me whether your modems are suitable.
  • USB Modems should work in a HiLink (or similar) mode (Virtual Ethernet Adapter). The best indicator of that is that you can visit their Web-GUI on the modem IP.
  • USB Modems that were proven to work well:
    • Huawei: E3372, E3531, E55xx, E8372
    • ZTE: MF920, MF83x, MF279, MF6xx, MF93D, MF79, MF971
    • Alcatel: LINKZONE 8349, IK41, MW40, MW4x
    • UF906 family: Anydata W150, KuWfi, TianJie
  • LTE modules, M.2 or mini-PCI-e:
    • Quectel: EC25, EC200, EP06
    • Sierra Wireless: EM7455
  • Modems suitable for the USA
  • 4G/5G LAN routers e.g. Huawei B311, and other Huawei Bxxx. Similar routers models support can be added by demand.
USB hub
  • One or two USB hubs with external power source.
  • It is better to have a “smart” USB hub, where the ports can be power cycled programmatically, but it is not mandatory.
  • at least 0.9 A guaranteed current per USB port
Linux box
  • A laptop or a cheap PC or a miniPC. We can also create a residential proxy on Raspberry Pi, but I have previously encountered some power issues with it. We need the CPU power on high bandwidth, so I prefer using a PC if possible.
  • Normally Raspberry PI can serve ~ 5 proxies, a miniPC – up to 10, a Laptop like Core i5 – up to 30. It depends on how heavily the proxies are used.
  • Recommended but not critical: fast download and upload of home “ground” internet, both >10mbps.
  • VPS in the cloud, in case you need to forward proxy ports to the Internet for a future rental. It should have at least 0.5 or 1 GB RAM and should be placed in close proximity to the rest of the hardware to make pings lower.
  • See price above, depending on a plan.

After we build your own 4g proxy farm, you would be able to:

  • surf the Internet through proxies, either from your LAN or (when the VPS is used) from the Internet
  • visit each modem’s WEB GUI through its corresponding proxy
  • add new modems
  • change MTU/TTL on the modems
  • forward proxy ports either via the individual cell WAN or via the LAN of the server
HTTP/CLI API calls (JSON is returned for each)
  • list present modems/proxies
  • change their settings
  • get bandwidth stats for each modem
  • request speed test for each modem
  • read\send SMS or USSD

Some other useful options:

  • proxy ACLs (what to allow/deny to proxy users)
  • automatic deployment of new servers
  • bandwidth throttling
