Tools That Work With a Mobile Proxy USA Line

A Mobile Proxy USA line is reached like any authenticated proxy: a host, an HTTP port, a SOCKS5 port, a username and a password, all shown on the line's card at area.mobileproxyusa.com. Any software that accepts those details will exit on the line's carrier address. This page lists the tools most of our customers pair with a line, with the exact settings for each. Two profile browsers come first because they are the right starting point for anyone running accounts; the rest cover whole-system routing, phones, scripts and quick checks.

Undetectable.io

Profile browser

Our first choice for running separate browser identities on Windows and Mac. Each profile has its own fingerprint, cookies and proxy; a built-in check reports the carrier and city of the line before launch; profiles can be kept locally or synced through the cloud for a team. The free tier is enough to run a handful of profiles on a handful of lines.

  1. Download Undetectable.io for Windows or Mac, install it and sign in.
  2. Open the proxy manager, add a SOCKS5 entry with the line's host, SOCKS5 port, username and password, and run the check.
  3. Create a new profile, choose the operating system fingerprint the account should present, and select the saved proxy.
  4. Set time zone, language and geolocation to follow the proxy, or set them by hand to the line's city and en-US.
  5. Launch the profile and confirm the carrier address on an IP lookup page before signing into anything.
  • Name each profile after its line and city so the pairing is obvious to anyone on the team.
  • After a free city move, edit the saved proxy once; every profile that uses it follows.

GoLogin

Profile browser

Our second choice, and the one for Linux users, teams that share profiles across machines, and anyone who wants to open the same profile from an Android phone. Profiles live in GoLogin's cloud with the proxy attached, and a check before launch confirms the line is live and in the expected city.

  1. Install GoLogin on your Windows, Mac, Linux or Android device and log in.
  2. Add a profile and accept the generated fingerprint for the operating system the account expects.
  3. In the Proxy tab choose SOCKS5 and enter the line's host, SOCKS5 port, username and password, or paste host:port:username:password.
  4. Click Check proxy and confirm the United States flag, the carrier and a city in the line's state.
  5. Leave time zone and geolocation on Based on IP, set language to en-US, save and run.
  • Opening the profile from the Android app sends the phone through the same line, so a second device shows the same address.
  • Keep a shared sheet of profile, line, city and renewal date so nobody launches an account on the wrong line.

Proxifier

Whole-system routing, Windows and Mac

Sends every application on a computer, or only the ones you choose, through a proxy, including programs with no proxy setting of their own. Useful when a desktop application, a game client or a tool with a hard-coded connection needs to leave on the line.

  1. Install Proxifier and open Profile, then Proxy Servers, and add the line's host and SOCKS5 port with authentication enabled.
  2. Under Rules, create a rule for the applications that should use the line, or set the default rule to the new server.
  3. Open a browser covered by the rule and confirm the carrier address on an IP lookup page.
  4. Add a rule that sends your IP-check tool directly, so you can compare the real and proxied addresses side by side.
  • Turn off any VPN client while Proxifier is active; two layers of routing on one machine produce confusing results.

FoxyProxy

Browser extension, Firefox and Chrome

A free extension that sends an ordinary browser through a proxy, either for every site or for sites matching patterns you define. The quickest way to look at a page from the line's city without setting up a profile browser.

  1. Add FoxyProxy to your browser from the Chrome Web Store or the Firefox Add-ons site.
  2. Add a proxy: type SOCKS5, the line's host and SOCKS5 port, and the username and password.
  3. Choose the mode: use the proxy for all URLs, or add patterns for the sites that should go through it.
  4. Load an IP lookup page and confirm the carrier and the state.
  • In Firefox, enable proxy DNS when using SOCKS5 so name lookups also leave through the line.
  • Extensions do not change the browser fingerprint; for account work use a profile browser instead.

Shadowrocket

iPhone and iPad

A paid iOS app that routes the whole device, or chosen apps, through a proxy or a VLESS tunnel. It is the simplest way to make an iPhone appear from the line's city, and it accepts the plain SOCKS5 login as well as the vless:// link from the dashboard.

  1. Install Shadowrocket from the App Store.
  2. Tap the plus button, choose SOCKS5, and enter the line's host, SOCKS5 port, username and password; or paste the vless:// link from the dashboard instead.
  3. Select the server, switch the connection on and allow the VPN configuration.
  4. Open Safari and confirm the carrier address on an IP lookup page.
  5. Set the device time zone to the line's city and turn off Location Services for the apps you will use.
  • Rotating the line from the dashboard changes the address without disconnecting the app.

Hiddify

Android, Windows, Mac and Linux tunnel client

A free, open-source client built on sing-box that imports the vless:// link from the dashboard and routes the whole device through the line on every platform. The usual choice for Android phones and for computers on networks that block proxy ports.

  1. Install Hiddify from Google Play, the Mac App Store or its GitHub releases.
  2. Copy the vless:// link from the line's card and choose Add from clipboard in Hiddify.
  3. Press connect and approve the VPN permission or system extension.
  4. Confirm the carrier address on an IP lookup page and check that WebRTC shows no other address.
  • If the client connects but nothing loads, check the device clock; the handshake needs accurate time.
  • A city move issues a new link; copy it again from the dashboard.

Python requests

Scripts and automation

The most common way customers run scheduled checks and collection jobs. Pass the line as the proxy for both http and https and every request in the session exits on the carrier address. The same proxy URL works in httpx, aiohttp, Scrapy and any library that reads a proxy setting.

  1. Build the URL socks5h://USERNAME:PASSWORD@HOST:SOCKS5PORT, or http://USERNAME:PASSWORD@HOST:HTTPPORT for HTTP.
  2. Create a requests.Session and set session.proxies to a dictionary with that URL under both http and https.
  3. Request an IP lookup endpoint first and assert the response names the carrier.
  4. Call the rotation link between batches, sleep a few seconds, and re-check the address before continuing.
  • Install the socks extra for requests so the socks5h scheme is available; the h suffix resolves DNS through the line.
  • Keep request rates at a human pace; a carrier address is tolerant, not infinite.

curl

Command line

The fastest way to prove a line works and the standard tool for one-off checks from a terminal. One flag routes a request through the line; the response from an IP lookup shows the carrier address.

  1. Run curl -x socks5h://USERNAME:PASSWORD@HOST:SOCKS5PORT followed by an IP lookup URL.
  2. Read the address and organisation in the response; it should name AT&T, T-Mobile or Verizon.
  3. Add the same -x flag to any other curl command that should exit on the line.
  4. To rotate, request the rotation link from the dashboard with a plain curl, wait a few seconds, and repeat the lookup.
  • Use -s and pipe to a JSON tool when scripting so the output is easy to parse.

Android Wi-Fi proxy

Built into Android

Android can route a Wi-Fi network's browser traffic through an HTTP proxy with no extra app, which is enough for web checks from the line's city. For every app on the phone, use Hiddify with the VLESS link instead.

  1. Open Wi-Fi settings, long-press the connected network and choose Modify or Advanced.
  2. Set Proxy to Manual and enter the line's host and HTTP port.
  3. Open the browser; when it asks for credentials, enter the line's username and password.
  4. Load an IP lookup page and confirm the carrier address.
  • This setting only affects browser traffic on that Wi-Fi network; apps and mobile data are unaffected.

Two facts that apply to every tool

First, the proxy only changes the network address. Time zone, language, screen size and GPS are set by the tool or the device, and for a convincing US identity they should match the line's city: Eastern time for New York, Boston, Miami and North Carolina; Central for Chicago and Houston; Mountain for Phoenix; Pacific for Los Angeles. Second, prefer SOCKS5 where a tool offers it, because it carries all protocols including UDP and does not depend on the tool's HTTP handling; use the HTTP port where only HTTP is offered. Both ports authenticate with the same username and password.

Why a profile browser first

Anyone running more than one account should keep each in its own browser profile with its own fingerprint and its own line. Undetectable.io and GoLogin do this well, store the proxy inside the profile so it cannot be opened on the wrong line, and offer a check button that shows the carrier and city before anything is loaded. They are the two we recommend, and the referral links below are ours.

Rotation and the tools

No tool below needs to know about rotation. A rotation is triggered from the dashboard, the rotation link, the API or a timer, and the next connection from any tool simply leaves on the new address. For account work, rotate with the profile closed. For collection scripts, rotate between batches and re-check the address before continuing. The VLESS tunnel, available on server-based lines, is an alternative to the plain login for phones and for networks that block proxy ports, and it carries whole devices through the line.

Integration questions

Which tool should a beginner start with?

Undetectable.io for a profile with its own fingerprint, or FoxyProxy for a quick look at a page. Scripts come later.

Do HTTP and SOCKS5 need separate credentials?

No. The same username and password work on both ports; only the port and the type differ.

Can one line be used by several tools at once?

Yes, within the line's connection limit. They all leave on the same carrier address.

Do you support other profile browsers?

Any tool that accepts an authenticated HTTP or SOCKS5 proxy works. Undetectable.io and GoLogin are the two we document and recommend.

Every tool here takes a standard proxy

Each dedicated US carrier line comes with HTTP and SOCKS5 ports and a username and password. US lines from $2 for two hours or $5 per day.
