The tools folks hook up to our lines

Undetectable.io

If you want a bunch of browser profiles that each look like a different computer, Undetectable.io is the one we tell people to try first. It works on Windows and Mac. Every profile gets its own fingerprint and its own proxy, and there is a button to test the proxy before you go anywhere. You can keep profiles right on your own computer or put them in the cloud so you can open them from somewhere else. The free plan lets you keep up to five profiles in the cloud, which is plenty to see if it fits how you work.

1. Download Undetectable.io for your Windows PC or Mac and make an account. The free plan is fine to start.
2. Sign in to USAProx and write down the server address, port, login and password for the line you want to use.
3. Make a new profile and decide if it lives on this computer or in the cloud.
4. Go to the profile's proxy spot, pick HTTP or SOCKS5 to match the port you wrote down, fill in the rest and hit the check.
5. When an American carrier comes back, set the time zone and language to match where the IP is, and save.

• Give each profile its own line. Two profiles on one line show up to websites with the very same address.
• A bigger paid plan lets you load your proxies in all at once and share profiles with the people you work with.

GoLogin

GoLogin is our second pick, and a good one if you hop between different kinds of computers. Its browser, called Orbita, runs on Windows, Mac and Linux, and there are apps for Android phones and iPhones too. Every profile has its own proxy box that takes HTTP, SOCKS4 or SOCKS5, plus a button to check it. You get three profiles free without putting in a card, and you can try the paid plans for seven days.

1. Sign up for GoLogin. No card is needed for the free plan.
2. Make a profile and open up its proxy settings.
3. Copy your line as one chunk, written host:port:user:pass, and drop it in the paste box, or fill in each blank yourself.
4. Hit the check proxy button and make sure it shows an American carrier in the city you expected.
5. Save it, open the profile, and you are set.

• Need a different city? Moving your line to another city we serve costs nothing and you do it yourself from the dashboard.
• If you open one profile from home and from the office, leave the IP alone in between so it looks the same in both places.

DuoPlus

DuoPlus rents you Android phones that live in a data center. You run them from a browser tab, install apps, and keep each one separate. Trouble is, out of the box those phones connect from a server farm, and plenty of American apps can tell. Put a USAProx line on each DuoPlus phone and it goes online through an honest-to-goodness US carrier, the way a phone in somebody's pocket would.

1. Log in to your USAProx account and jot down the server address, port number, login and password for one line.
2. Over in DuoPlus, pull up the settings for the cloud phone you want to fix up and look for its proxy spot.
3. Pick SOCKS5 or HTTP to match the port you wrote down, then fill in the rest.
4. Hit the proxy test DuoPlus offers. You want to see an American carrier name come back.
5. Power the phone on and load a what-is-my-IP site in its browser to double-check.

• Set the phone's clock and region to the same part of the country as your line before you sign in to any apps.
• One line per phone is the cleanest way to run it. Sharing a line means those phones show up with the same address.

VMOS Cloud

VMOS Cloud gives you full Android phones in the cloud that you drive from your computer or from their app. Each one has its own apps and storage. Folks use them to run app accounts for clients, try out an app the way someone in Houston or Phoenix would see it, and check prices that only show up on mobile. Our line swaps the hosting connection for a genuine American cell connection.

1. Grab the login info for a line off your USAProx dashboard.
2. Open the VMOS Cloud phone and head to wherever it keeps network or proxy options.
3. Pick which protocol you want, then enter the address, port, login name and password one at a time.
4. Run the connection check it offers and make sure it lands in the States.

• If an app still acts like it is overseas, check the phone's language and time zone. The proxy only fixes the connection.

GeeLark

GeeLark is another cloud phone service. Every phone profile runs Android in the cloud, and each profile gets its own proxy box. It suits people who work inside mobile apps all day and would rather not own a shelf of handsets. Drop a USAProx line into a profile and that phone reaches the internet the way real American phones do.

1. Copy a line's connection info from your USAProx account.
2. In GeeLark, edit the phone and look for where the proxy goes.
3. Choose between HTTP and SOCKS5, then type in the four pieces of info.
4. Test it, then start the phone and give it a quick look from its own browser.

• Hook up the line first and sign in to your apps second. That way the account never sees the phone on any other connection.

Selenium

Selenium is free software for making a browser click and type on its own, driven by code you write. It is great for checking your own site, watching prices or testing what shows up for American visitors. One catch: Chrome will not take a proxy login from its startup settings, so you need a small add-on or a local relay program to pass the password along.

1. Keep your USAProx login in environment variables, not written into the script.
2. In your browser setup code, point the proxy at the line's address and port.
3. Add a small extension or local relay that answers the login request, or handle the login popup in Firefox.
4. Make the first stop of every run a what-is-my-IP site, and print what it says.
5. When you want a new IP between runs, have the script call your line's rotation link.

• You can switch IPs as often as you like with no waiting, but doing it in the middle of a logged-in session tends to log you out.

Shadowrocket

Shadowrocket is an iPhone and iPad app that sends your phone's traffic through a proxy. It comes in handy when you want to look at an app or a website on your own iPhone the way somebody in Miami or Chicago would see it.

1. Buy and install Shadowrocket from the App Store.
2. Tap the plus button, set the type to HTTP or SOCKS5, and fill in the address, port, login and password from USAProx.
3. Save it, pick it from the list and flip the switch on. Your iPhone will ask to add a VPN setting, so say yes.
4. Open Safari and go to a what-is-my-IP site to see which carrier shows up.

• Flip it back off when you are done, or everything on your phone keeps riding the line.

Proxifier

Some programs on a computer have no place to type a proxy at all. Proxifier takes care of that. It sits on your Windows PC or Mac and pushes the programs you pick through your USAProx line, leaving everything else alone.

1. Install Proxifier and open its list of proxy servers.
2. Add a new one with your line's address and port, choose HTTPS or SOCKS Version 5 to match, and turn on the login with your username and password.
3. Click Check to make sure it connects.
4. Make a rule that names the program you want sent through the line.

• If you only want one program on the line, make sure the default rule says Direct, or your whole computer will use it.
