Tools and Apps That Work With a USA 4G Proxies Line

A line from us is reached in two ways, and almost every tool on earth supports at least one of them. The first is a plain authenticated proxy: a host, an HTTP port, a SOCKS5 port, a username and a password, shown in the dashboard the moment your $4 day pass activates. The second is a VLESS tunnel, a vless:// link that free phone and desktop clients import to send a whole device through the line. Below are the tools we see customers use most, with the steps for each and a tip or two from support. We recommend Undetectable.io first and GoLogin second for profile browsing; the rest are good free tools for specific jobs. Nothing here costs extra from us, and the links to Undetectable.io and GoLogin are referral links.

Undetectable.io

Profile browser

Our first recommendation for keeping browser identities apart on Windows and Mac. Each profile carries its own fingerprint, cookies and proxy, so a $4 line can be attached to exactly the profile that needs a US carrier address while other profiles use other lines. The built-in proxy check shows the exit IP and country before you launch, and the timezone can follow the IP.

  1. Create a new profile and open its Proxy section.
  2. Choose HTTP (or SOCKS5) and enter the host, port, username and password from your line.
  3. Press Check Proxy and confirm a United States result on your carrier.
  4. Set timezone and geolocation to follow the IP, then save and launch.
  5. Verify on an IP page inside the profile that the organisation is your carrier.
  • Name the profile after the metro so you remember which timezone it should carry.
  • Rotate between sessions, not during one; the profile needs no change after a rotation.

GoLogin

Profile browser

Our second recommendation, with Windows, Mac, Linux and a cloud mode. The proxy lives inside each profile, the connection check reports the exit IP and country, and timezone and geolocation can be derived from the IP. A good fit if you work from several computers and want the same profiles everywhere.

  1. Add a profile and open the Proxy tab.
  2. Pick HTTP or SOCKS5, paste host, port, username and password.
  3. Run the check and confirm United States.
  4. Set Timezone and Geolocation to 'based on IP'.
  5. Save, run, and confirm the carrier on an IP page.
  • If the check fails, the usual cause is the HTTP port paired with the SOCKS5 type or the reverse.
  • The city shown may be a regional hub on Verizon; check the state and the carrier instead.

Hiddify

VLESS client (Android, iOS, desktop)

A free, open-source client that imports a vless:// link from the clipboard or a QR code and creates a system-level tunnel, so every app on the device goes through the line. Our usual recommendation for Android phones and a good choice on iOS and desktop too.

  1. Install Hiddify from the Play Store, App Store or its project page.
  2. Copy the vless link from your line's dashboard page.
  3. Tap the plus button and choose 'add from clipboard'.
  4. Select the new profile and tap connect; allow the VPN prompt.
  5. Check an IP page in the phone browser for your carrier.
  • Set the phone's time zone to the metro so apps and the address agree.
  • Disconnect when finished; the pass keeps running for its 24 hours either way.

v2rayNG

VLESS client (Android)

A lightweight free Android client for VLESS and related protocols. Imports links from the clipboard or a QR code and runs as a VPN so all apps are covered. Preferred by people who want the smallest possible app.

  1. Install v2rayNG from the Play Store or its releases page.
  2. Copy the vless link from the dashboard.
  3. Tap plus, then 'import config from clipboard'.
  4. Tap the profile, then the connect button, and allow the VPN prompt.
  5. Verify the exit address on an IP page.
  • Use the per-app setting to leave your own banking app on the phone's own connection if you prefer.
  • After rotating the line, the tunnel stays up; only the exit address changes.

Streisand

VLESS client (iOS)

A free iOS and macOS client that imports vless links and runs as a system VPN. The simplest free route to sending an iPhone through a day pass.

  1. Install Streisand from the App Store.
  2. Copy the vless link on the phone or open the QR code on another screen.
  3. Tap plus and import from clipboard or scan the code.
  4. Select the server and toggle the connection on; allow the VPN configuration.
  5. Open Safari and check an IP page for your carrier.
  • If import fails, copy the link again; a trailing space breaks it.
  • Match the iPhone's time zone to the metro for consistency.

Shadowrocket

VLESS client (iOS, paid)

A well-known paid iOS client many people already own. Imports vless links, supports per-app rules, and runs as a system VPN so every app is covered.

  1. Open Shadowrocket and tap the plus button.
  2. Paste the vless link, or scan the dashboard's QR code.
  3. Select the new server and switch the connection on.
  4. Allow the VPN prompt the first time.
  5. Confirm the exit address on an IP page.
  • Keep 'global routing' on so all traffic uses the line.
  • The dashboard link is per line; import a new one when you buy a new pass.

Proxifier

System-wide proxy (Windows, Mac)

Forces applications that have no proxy setting of their own through a SOCKS5 or HTTP proxy, by application or for the whole system. Useful when a desktop app must look like it is on a US carrier connection.

  1. Add a proxy server with your line's host and SOCKS5 port.
  2. Enable authentication and enter the username and password.
  3. Create a rule for the application you want proxied, or set the default rule to the new proxy.
  4. Open the application and check its traffic appears in Proxifier's log.
  5. Verify the exit address with a browser rule or curl.
  • Use SOCKS5 here so UDP traffic is carried too.
  • Exclude your own tools, such as the dashboard, if you want them on your local connection.

FoxyProxy

Browser extension (Chrome, Firefox)

A free extension that switches your everyday browser onto a proxy with one click. The quickest way to glance at a site from a US address without a separate profile browser; it does not separate fingerprints, so use it for looking rather than for managing identities.

  1. Install FoxyProxy and open its options.
  2. Add a proxy with type HTTP (or SOCKS5), the host and the port.
  3. Enter the username and password in the authentication fields.
  4. Select the proxy from the toolbar icon.
  5. Load an IP page and confirm your carrier.
  • Switch back to 'direct' when done so your own browsing stays on your own connection.
  • Your browser's timezone will not change; use a profile browser if a site compares the two.

Android Wi-Fi proxy

Built-in phone setting

Android lets you set an HTTP proxy on a Wi-Fi network. It covers the browser and some apps, but many apps ignore it, so it is a quick check rather than a full solution; the VLESS tunnel is the full solution.

  1. Open Wi-Fi settings, long-press the connected network, choose Modify.
  2. Set Proxy to Manual and enter the host and HTTP port.
  3. Save, open the browser, and sign in with the username and password when prompted.
  4. Check an IP page.
  5. Set Proxy back to None when done.
  • Only applies on that Wi-Fi network, not on mobile data.
  • If an app shows your real address, it bypassed the setting; use Hiddify instead.

iOS Wi-Fi proxy

Built-in phone setting

iOS has the same per-network HTTP proxy setting as Android, with the same limits: Safari obeys it, many apps do not. Fine for a quick look in Safari; use Streisand or Shadowrocket for everything else.

  1. Open Settings, Wi-Fi, tap the i next to the connected network.
  2. Under HTTP Proxy choose Manual.
  3. Enter the host and HTTP port, turn on Authentication, enter username and password.
  4. Open Safari and check an IP page.
  5. Set it back to Off when finished.
  • The setting is forgotten if you join a different network.
  • For apps, the VLESS tunnel is the reliable route.

curl

Command line

The one-line way to prove a line works and to script simple checks. Supports HTTP and SOCKS5 proxies with authentication out of the box on every operating system.

  1. Open a terminal.
  2. Run curl with -x and your line as user:pass@host:port against an IP-echo service.
  3. For SOCKS5, prefix the proxy with socks5h:// so DNS resolves through the line.
  4. Read the returned address and look it up to confirm the carrier.
  5. Rotate from the dashboard and run it again to see the address change.
  • Use socks5h rather than socks5 so hostname lookups do not leak from your own connection.
  • Add -w with time_total to compare 4G and 5G lines fairly.

Python requests

Scripting

The standard Python HTTP library takes a proxies dictionary with your line's credentials and works for both HTTP and SOCKS5 (with the socks extra installed). Good for small checks and gentle automation on your own accounts.

  1. Install requests, and requests[socks] if you want SOCKS5.
  2. Build a proxies dict with http and https keys pointing at user:pass@host:port.
  3. Pass proxies= to your request and fetch an IP-echo URL.
  4. Confirm the carrier, then run your own job.
  5. Call the rotation link with a plain GET when you want a fresh address.
  • Keep a sensible pace; a 4G line is a phone connection, not a datacenter link.
  • Use socks5h in the proxy URL so DNS goes through the line.

Before you start: three facts about the line

First, the HTTP and SOCKS5 ports share one username and password, and both exit from the same carrier address; pick whichever a tool asks for. Second, rotation happens on our side, so no tool needs to be told about it: when you rotate, the exit address changes and the tool keeps working with the same settings. Third, the line is a single address at a time, so two tools on the same line share one exit IP; that is fine for one person's work and wrong for two unrelated identities, which want two lines at $4 each.

Which tool for which job

Several separate browser identities on a desktop: Undetectable.io or GoLogin. A whole phone through the line for a day: Hiddify, v2rayNG, Streisand or Shadowrocket with the VLESS link. One desktop app that has no proxy setting of its own: Proxifier. A quick look at a site from a US address in your normal browser: FoxyProxy. A script or a one-line check: curl or Python requests. Only a browser on a phone, without a tunnel: the Android or iOS Wi-Fi proxy setting, with the caveat that many apps ignore it.

A note on speed

A 4G line is rated at up to 25 Mbps download and a 5G line at up to 50 Mbps. Every tool listed here is comfortable on 4G for ordinary browsing and app use. If you push video or many simultaneous sessions through one line, the $5 5G pass is the step up, and the tools are configured identically.

Integration questions

Which tool should I start with if I have never used a proxy?

Undetectable.io on a desktop, or Hiddify on a phone. Both show you the exit address before you do anything else.

Do I have to change anything in a tool after I rotate the address?

No. Rotation happens on our side. Host, port and credentials stay the same; only the exit address changes.

Can two tools share one line?

Yes, and they will share one exit address. That is fine for one person's work; for separate identities, buy a second $4 line.

Does any of this need the 5G line?

No. Every tool here runs comfortably on a 4G line at $4. The $5 5G line is for video and heavy traffic.

Every tool here takes a standard proxy

You get HTTP and SOCKS5 ports and a username and password on your own US carrier line. A day pass is $4; two hours are $2.
