Your dedicated line, inside the tools you already use

Undetectable.io

Undetectable.io is where we suggest you begin if a dedicated line is going to sit behind a browser profile for the long haul. Each profile keeps its own fingerprint and its own proxy, so one profile on one line stays the same quiet pairing day after day. You can store profiles locally on your own computer or in the cloud to open them from another device, on Windows or macOS. The free plan holds up to five cloud profiles, and paid plans add room, proxy import and sharing with team members.

1. Download Undetectable.io for Windows or macOS and sign in; the free plan is enough to try one line.
2. Create a new profile and choose whether to keep it on your device or in the cloud.
3. Open the profile's proxy settings, pick HTTP or SOCKS5, and enter the host, the matching port, the username and the password.
4. Use the proxy check and confirm the carrier and US city of your line.
5. Leave timezone, language and geolocation following the proxy IP and keep WebRTC on the proxy's address.
6. Save the profile and browse a few ordinary pages before signing in to anything.

• Give each profile its own line and keep it there; a dedicated line works best when nothing about the pairing changes.
• If you ever rotate the line, close the profile first and reopen it once the new address is up.

GoLogin

GoLogin is the alternative we recommend, and the better fit if you want your profiles on Linux too or on a phone, since it runs on Windows, macOS and Linux and has Android and iOS apps. Profiles open in its Orbita browser with a proxy set per profile. You can begin on the free plan with three profiles and no card, or take the 7-day trial of a paid plan, which also brings team sharing and an API for automation.

1. Create a GoLogin account and start with the free plan or the 7-day trial.
2. Add a profile and go to its proxy section.
3. Choose HTTP or SOCKS5 for your dedicated line.
4. Paste host:port:user:pass from your dashboard into the paste field so all four values land at once.
5. Press check proxy and wait for your line's carrier address to appear.
6. Save and launch the profile, then leave it on that line for as long as the account lives.

• Keep the paste string in a password manager rather than in profile notes, so the line stays private.
• Rotate only between sessions; a steady address is the whole point of a dedicated line.

GeeLark

GeeLark provides Android phones that run in the cloud, each with its own apps and device identity and its own proxy setting. All traffic from the virtual phone uses the proxy, so the connection matters even more than in a browser. A dedicated carrier line gives the cloud phone a network that fits what it is: a phone.

1. Open the cloud phone's settings and find the proxy option.
2. Choose HTTP, or SOCKS5 if apps on the device rely on calls or live video.
3. Enter host, port, username and password.
4. Use the proxy check to make sure the address is a US carrier one.
5. Align the phone's region and timezone with the result and start the device.

• Keep each cloud phone on the same line over time; frequent swaps make an app's history harder to follow.
• Each line includes 15 GB per day, which is plenty for typical app use, though large app installs are best done early in the day.

Selenium

Selenium controls real browsers from code. The proxy is set through browser options when the driver starts, and because launch flags cannot carry a username and password, an authenticated line is usually added through a small extension or a local forwarding proxy. It fits steady, repeatable checks run against sites you are allowed to test.

1. Choose which port you will use, HTTP or SOCKS5.
2. Add the host and port to the browser options before the driver launches.
3. Handle credentials with a proxy-auth extension or a local forwarder.
4. Visit an IP lookup page first and confirm the carrier.
5. Continue with your script once the address looks right.

• A single dedicated line per driver keeps results tidy and makes troubleshooting calm and quick.

Playwright

Playwright automates Chromium, Firefox and WebKit through one API and takes a proxy with server, username and password when the browser starts, so a dedicated line needs no workarounds. It suits calm, repeatable checks: the same pages, the same line, the same results every time.

1. Copy the host, HTTP port, username and password for the line.
2. Pass them as the proxy option when launching the browser, writing the server as http://host:port.
3. Open an IP lookup page first and confirm the carrier.
4. Run your checks, keeping one browser per line.
5. Close the browser at the end so the connection to your device is released.

• Chromium does not take a password for SOCKS5, so the HTTP port is the easy choice here.

Proxifier

Proxifier routes desktop programs that lack proxy settings through your line, with rules that decide which applications go where. On a dedicated line that means one desktop app can sit on a private carrier address while the rest of the computer uses your normal connection.

1. Open the proxy server list and add the line's host and port.
2. Pick HTTPS for the HTTP port or SOCKS Version 5 for the SOCKS5 port, and tick authentication to add username and password.
3. Run the check and wait for a successful connection.
4. Add a rule naming the program that should use the line.
5. Start the program and confirm in the log that it connects through the proxy.

• Have hostnames resolved through the proxy so the program's DNS lookups do not leave from your home network.

Shadowrocket

Shadowrocket is a paid iPhone and iPad app that sends the device's traffic through a proxy you add. With a dedicated line it lets you look in on a US account from your own iPhone on the same carrier address your desktop profile uses, which keeps the picture consistent.

1. Install Shadowrocket from the App Store and tap the plus button to add a server.
2. Choose HTTP or SOCKS5 as the type.
3. Enter the host, the matching port, and the username and password.
4. Save, select the server and switch the connection on, allowing the VPN configuration when iOS asks.
5. Open an IP lookup page in Safari and confirm your line's carrier.

• Switch Shadowrocket off when you are done so personal apps go back to your own connection.

curl

curl is the quickest way to prove a dedicated line works before you open any other tool. One command through the proxy shows the exit IP, and if curl gets through while an app does not, you know the problem sits in the app's settings rather than on the line.

1. Open a terminal on any machine with curl installed.
2. Run curl with the -x option and the proxy written as http://user:pass@host:port.
3. Point it at an IP echo service and note the address it returns.
4. Repeat with socks5h://user:pass@host:port on the SOCKS5 port to test that protocol too.
5. Compare the address with the one your dashboard shows.

• If the password contains symbols, percent-encode them in the URL or pass the credentials with --proxy-user instead.
