Tools we have seen work, and how to check for yourself

Incogniton

Incogniton gives every profile its own fingerprint, cookies and storage, and it takes a proxy per profile over HTTP(S) or SOCKS5. It is a solid, affordable starting point if you are new to anti-detect browsers. A mobile line is worth it here when the profile must look like a US phone user; for a quick one-off look at a page, a cheaper route may do.

1. Have your dashboard open on the line you want so the values stay visible.
2. Create or edit a profile and go to the proxy settings.
3. Choose the protocol first, then copy the port that belongs to it.
4. Paste the host, username and password.
5. Run the check and read the result yourself: a US IP, a carrier ISP and a city you recognise.
6. Leave timezone and geolocation automatic and save.

• After the built-in check, load an independent IP lookup inside the profile too. Two sources agreeing is a better test than one.
• A Houston line should give a Central timezone; if the profile shows something else, a setting is overriding the IP.

FoxyProxy and SwitchyOmega

FoxyProxy and Proxy SwitchyOmega are free browser extensions that switch your browser's proxy from the toolbar, with optional rules that send only certain sites through a proxy. They are the cheapest, lightest way to use a mobile line: no extra app, just your normal browser. They do not change fingerprints, so they suit checking pages and prices rather than managing separate identities.

1. Install the extension and open its options.
2. Add a proxy entry named after the line's metro and carrier.
3. Select HTTP with the HTTP port, or SOCKS5 with the SOCKS5 port.
4. Enter the host and the credentials, and save the entry.
5. Switch it on and open an IP lookup page to confirm the carrier address.

• Use rule-based switching so only the sites you are testing go through the line and everything else stays on your own connection; it saves daily data.
• If the browser shows its own login box for a SOCKS5 entry, try the HTTP port instead.

Proxifier

Proxifier forces desktop applications that have no proxy settings of their own through a proxy you choose, using rules by application or destination. It is useful when you want to test how a desktop app or game launcher behaves on a US mobile connection. It routes traffic only; it does not disguise the device.

1. Add a new proxy server with the line's host and port.
2. Set the protocol to HTTPS or SOCKS5 to match that port, and enable authentication with your username and password.
3. Use the built-in proxy test and confirm it connects.
4. Create a rule that sends only the target application through this proxy.
5. Start the application and watch the connection log to confirm traffic takes the proxy.

• Keep DNS resolution on the proxy side if the app is sensitive to location, so lookups do not reveal your home network.

GoLogin

GoLogin is an anti-detect browser with cloud-synced profiles and a free tier, which makes it easy to try before committing. Proxies are set per profile. A mobile line makes sense once you are running accounts that are normally used on phones.

1. Open the profile and switch to the proxy options.
2. Pick the protocol and paste the port that belongs to it.
3. Add the host and the line's credentials.
4. Run the proxy check and verify the IP, carrier and timezone.
5. Save the profile.

• Try one profile first and run it for a day before copying the setup to others. It is a cheap way to catch mistakes.

AdsPower

AdsPower is a profile-based anti-detect browser with team features and automation. It is widely used for ad and store management. Put a mobile line behind a profile when the account in question expects mobile traffic; for desktop-only admin work, weigh whether you need it.

1. Open the profile's proxy settings.
2. Select HTTP or SOCKS5.
3. Enter host, port, username and password from the dashboard.
4. Use the check action and confirm the carrier and US location before saving.

• Keep a small log of when you rotated each line. If something odd happens later, you will know whether the address changed.

BitBrowser

BitBrowser is built for many windows and bulk profile work, with proxy import. It is practical if you already own several lines and want to manage them together. Test each imported line individually rather than trusting the batch.

1. Import your lines as a list or add one to a profile's proxy section.
2. Confirm protocol and port match for each entry.
3. Add usernames and passwords.
4. Run the proxy detection on every profile before using it.

• A failed check after import is almost always a column in the wrong order; compare one row to the dashboard.

MostLogin

MostLogin is a newer anti-detect browser with per-profile proxies and a simple interface. It is worth a look if heavier tools feel like more than you need. Our lines work in it like any other standard proxy.

1. Create a profile and open its proxy configuration.
2. Set HTTP or SOCKS5.
3. Add host, matching port and credentials.
4. Test, confirm the result and save.

• Newer tools change quickly; if a field moves after an update, the four values you need stay the same.

Multilogin

Multilogin is a long-standing, full-featured anti-detect browser aimed at teams with automation needs. It costs more than some alternatives, which is worth knowing up front. A mobile line pairs well with its long-lived profiles.

1. Open the profile and find the proxy section.
2. Choose the connection type to match your port.
3. Paste the host, port, username and password.
4. Run the connection test and save when it passes.

• Enable WebRTC protection so the profile exposes only the proxy address, then confirm it on a WebRTC leak test page.

GeeLark

GeeLark runs Android phones in the cloud, each with its own apps and device identity, and lets you set a proxy per device. Because the whole phone uses the proxy, a mobile carrier line is a natural fit, and a datacenter proxy is a poor one. Consider it when your work lives in mobile apps.

1. Open the cloud phone and go to its proxy settings.
2. Choose HTTP, or SOCKS5 if apps need UDP for calls or video.
3. Enter host, port, username and password.
4. Run the proxy check and confirm the carrier.
5. Match region and timezone to the result, then start the phone.

• Each line includes 15 GB per day. App installs and video eat data fastest, so watch usage in the first week.

Selenium

Selenium drives real browsers from code. You pass the proxy in the browser options at launch; for an authenticated line you add a small extension or a local forwarder, because launch flags have no place for a password. Good for repeatable checks such as regional price comparisons.

1. Pick the port for HTTP or SOCKS5.
2. Add the host and port to the browser options.
3. Supply credentials through an auth extension or a local forwarder.
4. Assert the carrier on an IP lookup page as the first step of the script.
5. Run the rest of your checks.

• Make the IP assertion fail the run if the carrier is missing, so you never collect data over the wrong connection by accident.
