Four dollars, one day, and the tools you already own
A day pass is short, so the setup has to be shorter. Everything 4G Proxies USA hands you fits on one line of the dashboard: a hostname, a port for HTTP, a port for SOCKS5, a username and a password. Below are eleven places people paste those values, from the two profile browsers we recommend down to a single flag on a Chrome shortcut. Each entry says what the tool is good for on a one-day line, the handful of clicks or lines it takes, and the mistake to avoid. None of this is specific to the day pass; a $25 week or a $60 month uses the same five values in the same places, and so does a two-hour purchase.
Undetectable.io
Anti-detect browserWhere we send anyone whose day involves an account rather than a plain page view. Undetectable.io keeps a separate fingerprint for every profile, stores the proxy inside the profile, and tests the proxy before the window opens so a wrong line is caught early. On a day pass the routine is simple: today's values go into the profile in the morning and tomorrow's replace them the next day, while the fingerprint the account knows stays the same. Windows and Mac, local or cloud profiles, free tier available.
- Download Undetectable.io for your desktop, register and sign in.
- Make a new profile and open its proxy settings; select the type that matches the port you copied, HTTP or SOCKS5, and fill in host, port, login and password.
- Run the built-in proxy test and read the result: it should name a US carrier and your line's city.
- Match the profile's clock and language to that city, save it, and start the profile.
- Visit any address-check page inside the profile before you touch the account, then work.
- Do not open two profiles on the same pass at once; a website would see one address doing two people's work.
- Rotation inside a signed-in session logs you out of nothing, but it does change the address mid-visit, so save rotation for the gaps between tasks.
GoLogin
Anti-detect browserThe profile browser we name second, and the first choice when the desk runs Linux, when you want to launch a profile from an Android handset, or when a small team needs the same profiles on different machines. The proxy lives in the profile and can be verified before launch. It also has a free tier, so a four-dollar line in a free profile browser costs exactly four dollars for the day.
- Get GoLogin for Windows, Mac, Linux or Android and create an account.
- Start a new profile and let it generate a fingerprint for the operating system the account should appear from.
- In the proxy tab pick HTTP or SOCKS5, type in the line's host, port, username and password, and press the verification button.
- Accept the time zone and language GoLogin reads from the proxy, or set them to the line's city yourself.
- Open the profile, glance at an address-check page, and keep that profile paired with that account from now on.
- Launching the same profile from the Android app exits through the same line, so the site sees one address from a second device.
- Write the pass expiry time into the profile's notes field; it stops a teammate launching the profile after the line has gone.
Python requests
Scripts and automationThe usual way a scheduled check, a price sweep or a small collector gets onto the line. Requests takes a proxies dictionary, and once both the http and https keys point at the day pass, every call in the script leaves from the carrier address. Because a script does not care which day it is, the only thing that changes between passes is the string holding the host, port and login, so keep it in one place.
- Write the proxy string once: http://USERNAME:PASSWORD@HOST:PORT for the HTTP port, or socks5h://USERNAME:PASSWORD@HOST:PORT for SOCKS5 with DNS done on the far side.
- Create a Session and set session.proxies to a dictionary with that string under both http and https.
- Fetch an address-check endpoint first and stop the script if the answer is not a US carrier.
- Space the requests out like a person would, and hit the rotation link from the dashboard between batches rather than between pages.
- Prefer socks5h over socks5; the trailing h sends name lookups through the line too.
- Give every request a timeout and a retry. A rotation takes a few seconds and anything in flight during it fails.
curl
Command lineThe quickest proof that a pass is alive. One flag routes a request through the line, and the reply from an address-check endpoint shows the carrier. It is also the handiest way to trigger a rotation, because the rotation link in your dashboard is a plain URL. Many customers never go further than curl for one-off checks, and for a line that only lasts a day that is a reasonable place to stop.
- Export the login once: export PROXY=http://USERNAME:PASSWORD@HOST:PORT, or the socks5h form for the SOCKS5 port.
- Call curl -x "$PROXY" against an address-check endpoint and read the carrier name in the reply.
- Reuse the same -x flag on any other curl command that should leave through the pass.
- Fetch the rotation link with a plain curl, wait a few seconds, and repeat the address check to see the new address.
- Keeping the login in a variable also keeps it out of your shell history and out of screenshots.
Chrome command-line proxy flag
Browser launch optionChrome has no proxy page of its own, but it accepts a proxy on the command line, which turns out to be perfect for a day pass: one shortcut opens a separate Chrome that uses the line, and your normal Chrome never notices. A second flag gives that Chrome its own profile folder so cookies and history stay apart. Chrome prompts for the login the first time a page loads. Works on Windows, Mac and Linux.
- Quit Chrome, then start it with --proxy-server=http://HOST:PORT (or socks5://HOST:PORT) and --user-data-dir pointing at a fresh, empty folder.
- Type the line's username and password into the prompt Chrome shows on the first page load.
- Open an address-check page in that window and read the carrier and city.
- Name the shortcut after the city; tomorrow's pass is then a thirty-second edit of host and port.
- With the HTTP port the proxy resolves names for you. With SOCKS5, add --host-resolver-rules so Chrome does not leak lookups locally.
Firefox network settings
Built-in browser settingFirefox keeps its own proxy settings independent of the operating system, so a single Firefox install can live on the day pass while everything else on the machine stays on your normal connection. Nothing to install. The setting is three fields deep in Preferences and reverts to no proxy with one radio button when the pass expires, which makes Firefox a tidy choice for a day of checks in one browser.
- Open Preferences, search for the word proxy and click the Network Settings button.
- Choose manual configuration; put the line's host and HTTP port in the HTTP field, or the host and SOCKS5 port in the SOCKS field with v5 selected.
- Turn on the option that proxies DNS over SOCKS v5, then confirm.
- Load an address-check page; Firefox asks for the username and password once and remembers them for the session.
- Firefox's own fingerprint stays yours, so set the browser's time zone to the line's city if the day's work touches an account.
FoxyProxy
Browser extensionAn extension for Firefox and Chrome that switches a normal browser onto a proxy and back with a click, and can limit the proxy to a list of sites by pattern. For one person, one identity and a day of looking at pages from the line's city, it is the least ceremony of any browser option here, and the toggle in the toolbar makes the end of the day a single click.
- Add FoxyProxy from your browser's extension store and open its options.
- Create a proxy entry with the line's host, the HTTP or SOCKS5 port, the matching type, and the username and password.
- Decide whether every site or only a pattern list goes through the entry, and enable it from the toolbar icon.
- Check an address page and confirm the carrier and city before you start.
- Disable WebRTC in the browser, otherwise a site can discover your real address around the proxy.
- Set the browser's time zone and language to the line's city; an extension changes the route, not the fingerprint.
Proxifier
System-wide helper for Windows and MacProxifier catches the network traffic of any program on the computer, or only the programs you name, and sends it through a proxy, including programs that have no proxy setting at all. That makes it the answer when a seller desktop app, a messaging client or a game launcher has to appear from the day pass. One server entry plus one rule does it, and the rule can be switched off when the line ends.
- Install Proxifier and add a proxy server using the line's host, its SOCKS5 port and the login.
- Write a rule that applies the server to every application, or only to the ones you list by name.
- Open a browser, confirm the carrier address, then launch the program you actually wanted on the line.
- Leave the 4G Proxies USA dashboard and your own tools out of the rule so they keep using your real connection.
Android Wi-Fi proxy
Built-in Android settingAndroid can route browser traffic on a Wi-Fi network through an HTTP proxy from its own settings, with nothing to install. It is the cheapest setup on this page: a four-dollar pass and a field that already exists on the phone. It covers browsers and some apps, which is enough for checking how a page or a listing looks from the line's city. For the entire phone, a SOCKS5 client app or the VLESS link in your dashboard is the fuller option.
- In Wi-Fi settings, hold the network you are connected to and choose the option to modify it, then expand the advanced section.
- Switch the proxy field to manual and enter the line's host and HTTP port.
- Open the browser; when it prompts for a login, enter the line's username and password.
- Visit an address-check page and read the carrier.
- Set the phone's time zone to the line's city for the day.
- The setting belongs to that one Wi-Fi network, so switching networks switches the proxy off.
iOS manual proxy
Built-in iPhone settingAn iPhone can also send Wi-Fi browser traffic through an HTTP proxy from Settings, without an app. Safari and most web views honor it; many apps do not. For a day of checking pages, listings and ads from the line's city in Safari it is enough, and because the setting is tied to one Wi-Fi network, it is easy to switch off when the pass runs out.
- Open Settings, tap Wi-Fi, then tap the small i beside the network you are on.
- Under HTTP Proxy choose Manual and type the line's host and HTTP port.
- Enable Authentication and enter the username and password.
- Open Safari and confirm the carrier on an address-check page.
- Turn the proxy back to Off when the pass ends, or Safari will sit there failing to load.
- For apps beyond Safari, Shadowrocket below is the tool.
Shadowrocket
iPhone appA paid App Store app that pushes the whole iPhone, or chosen apps, through a proxy. It takes HTTP and SOCKS5 logins directly, so there is no tunnel to build, and it is the simplest way to make an iPhone appear from the day pass when the thing under test is an app rather than a web page. Set it up once; on later days only the server entry changes.
- Buy and open Shadowrocket, then add a server of type HTTP or SOCKS5 with the line's host, port, username and password.
- Pick that server and flip the connection on, allowing the VPN configuration iOS requests.
- Check the carrier in Safari before opening the app you want to test.
- Set the phone's time zone to the line's city and switch off location services for the apps you run through it.
- If the Wi-Fi you are on blocks proxy ports, use the VLESS link from your dashboard instead.
Everything is a host, two ports and a login
Open any line at me.4gproxiesusa.com and the panel shows the same five values whatever the plan: host, HTTP port, SOCKS5 port, username, password. There is no tool on this page that needs a sixth. Behind them sits one real AT&T, T-Mobile or Verizon SIM in a modem, cellular router or Android phone we own, in the city you chose, with nobody else's traffic on it for the term. Either port lands on the same SIM and the same address; the SOCKS5 port also carries UDP, and the socks5h scheme pushes name lookups through the line as well.
Price is independent of the tool. A 4G line is $4 for a day, $25 for a week or $60 for a month; 5G is $5, $28 or $65. A two-hour job can use the hourly purchase, $2 for the first two hours on 4G, and if it turns into a full day the hours already paid count toward the $4. Data is unlimited for proxy work on all of them, and a line can be moved to another of our cities for free with the time left intact.
Pick the tool by the job, not by habit
If an account is involved, start with Undetectable.io or GoLogin; a plain browser carries the same fingerprint whatever line is behind it, and a profile browser gives each account its own. If the job is a script, requests or curl is the whole answer. If you want to look at a few pages as a person in the line's city, FoxyProxy, the Chrome flag or Firefox's own settings take a minute and undo in a second. If a desktop program with no proxy setting has to appear from the line, Proxifier. If the thing being tested is a phone app, Shadowrocket on iPhone or a SOCKS5 client on Android; if it is a phone web page, the built-in Wi-Fi proxy on either phone is enough.
Habits that keep a day cheap
Look at the address before the work starts, every day; it takes a second and avoids spending an hour on the wrong line. Match the time zone and language of the tool to the city of the line. Turn WebRTC off in any plain browser. Rotate in the gaps between tasks rather than in the middle of a login. Keep one line per identity, and buy a second pass for a second identity rather than sharing one. And keep in mind what a proxy is: a different place for your traffic to enter the internet, nothing more. Run only the accounts you are entitled to run and respect every site's rules.
When the pass expires, each tool above returns to normal with one toggle, one flag removed or one rule disabled. The next morning, a new pass or a week plan, the same five values pasted into the same profile or script, and the day begins again.
When it will not connect
First check the clock: a day pass is exactly 24 hours from activation. Then check which port went with which type; an HTTP port in a SOCKS5 field is the most common cause of a dead connection. Then try curl with the same values, which separates a tool problem from a line problem. If curl fails as well and the dashboard shows the line as up, email [email protected] or message @FourGProxiesUSABot and a person will test the line from our side and credit any downtime that turns out to be ours.
Integration questions
What is the fastest way to use a day pass for a few page checks?
FoxyProxy or Firefox's own proxy settings in a browser, or curl in a terminal. Any of them is under a minute from paste to first page.
Can a profile browser and a script share one pass?
Yes, within the line's connection limit, and both will show the same carrier address. Share a pass only between things that should look like one person.
What changes when I buy the next day's pass?
Only the host, the port and the login. Paste the new values into the existing profile, extension, shortcut or script and leave everything else as it was.
