Putting your SIM into the tools you already use

A SimProxies line is an ordinary proxy with a login: a host, an HTTP port, a SOCKS5 port, a username and a password. Anything that accepts those will run on your SIM. This page collects the tools our customers set up most, with the steps for each, starting with the two profile browsers we recommend, Undetectable.io first and GoLogin second, then the small helpers for browsers, computers, phones and scripts. One rule applies to all of them: one SIM per identity, kept together for the month.

Undetectable.io

Anti-detect browser

Our first recommendation for running several browser profiles that each look like a separate device. Each profile carries its own fingerprint and its own proxy, with a check button that tells you the carrier and city before you open anything. Profiles can live on your machine or in the cloud, and the free plan is enough to try the pairing with a SIM.

  1. Install Undetectable.io on Windows or Mac and create an account.
  2. Copy the host, port, username and password of your SIM from the SimProxies dashboard.
  3. Create a profile, open its proxy section, choose HTTP or SOCKS5 to match the port, paste the values and press check.
  4. When the check reports a US carrier in your SIM's city, set the profile's time zone and language to that city and save.
  5. Launch the profile, load an IP check page, confirm the address, then sign in to the account that will live on this SIM.
  • One profile per SIM. Two profiles on one SIM appear to websites from the same address at the same time.
  • Rotate the SIM only between sessions, never while a profile is signed in.

GoLogin

Anti-detect browser

Our second recommendation, and the one to pick if you work on Linux, want to open a profile from an Android phone, or share profiles across a team. The proxy belongs to the profile and can be checked before launch, which is the feature that stops a profile being opened on the wrong line.

  1. Install GoLogin on Windows, Mac, Linux or Android and sign in.
  2. Create a profile and let GoLogin generate the fingerprint for the operating system the account expects.
  3. In the profile's proxy settings choose HTTP or SOCKS5, paste the SIM's host, port, username and password, and run the check.
  4. Set the time zone and language to the SIM's city, or let GoLogin take them from the proxy.
  5. Launch, confirm the address on an IP check page, and keep this profile on this SIM for the life of the account.
  • Opening the same profile from the Android app goes through the same SIM, so the site sees the same address from a second device.
  • Keep a shared list of profile, SIM, city and renewal date so nobody launches a profile on another line.

FoxyProxy

Browser extension

A Firefox and Chrome extension that routes a normal browser through a proxy, with rules for which sites use it. Good for a quick check from your SIM's city without a full profile browser, and for people who only need one identity in one browser.

  1. Install FoxyProxy from your browser's extension store.
  2. Add a new proxy: type HTTP or SOCKS5, the SIM's host and matching port, then the username and password.
  3. Set the extension to use that proxy for all sites, or add patterns for only the sites you want through the SIM.
  4. Load an IP check page and confirm the address is a US carrier in your SIM's city.
  • A normal browser keeps its own fingerprint, so set the browser's time zone and language to the SIM's city yourself.
  • Disable WebRTC in the browser, or the site can learn your real address through it.

Proxifier

System-wide helper for Windows and Mac

Sends every application on a computer, or a chosen list of them, through a proxy, including programs that have no proxy setting of their own. Useful when a desktop app or a game client needs to appear from your SIM.

  1. Install Proxifier on Windows or Mac.
  2. Add a proxy server with the SIM's host, the SOCKS5 port, and the username and password.
  3. Create a rule that sends all applications, or only the ones you name, through that server.
  4. Open a browser and an IP check page to confirm the address, then start the application you wanted on the SIM.
  • Exclude your SimProxies dashboard and your local tools from the rule so they stay on your normal connection.

Shadowrocket

iPhone app

A paid iPhone app that routes the whole phone, or chosen apps, through a proxy. It is the simplest way to make an iPhone appear from your SIM, and it supports both HTTP and SOCKS5 logins directly, with no tunnel needed.

  1. Install Shadowrocket from the App Store.
  2. Add a server: choose HTTP or SOCKS5, enter the SIM's host and matching port, then the username and password.
  3. Select the server and switch the connection on, approving the VPN profile iOS asks for.
  4. Open Safari and an IP check page to confirm the address is a US carrier in your SIM's city.
  • Set the phone's time zone to the SIM's city and turn off location services for the apps you use through it.
  • For hotel or office networks that block proxy ports, use the VLESS tunnel from your dashboard instead.

Android

Built-in Wi-Fi proxy on Android

Android can send a Wi-Fi connection's browser traffic through an HTTP proxy with no extra app, which is enough for web checks from your SIM's city. For every app on the phone, a proxy client app or the VLESS tunnel does the full job.

  1. Open the Wi-Fi settings, long-press the network you are on and choose modify or advanced options.
  2. Set the proxy to manual and enter the SIM's host and HTTP port.
  3. When the browser asks for a login, enter the SIM's username and password.
  4. Load an IP check page in the browser and confirm the address.
  • The built-in setting covers browsers and some apps only. For the whole phone, use a SOCKS5 client app or the VLESS link from the dashboard.
  • Match the phone's time zone to the SIM's city.

Python requests

Scripts and automation

The most common way our customers run a scheduled check or a collection job. Pass the SIM as the proxy for HTTP and HTTPS and the whole script exits on the carrier address. Works the same way in any library that reads a proxies setting.

  1. Build the proxy URL as http://USERNAME:PASSWORD@HOST:PORT using the SIM's HTTP port, or socks5h://USERNAME:PASSWORD@HOST:PORT for SOCKS5 with remote DNS.
  2. Pass it as both the http and https entries of the proxies dictionary on each request or on a session.
  3. Make one request to an IP check endpoint and assert the response is a US carrier address before running the job.
  4. Pace the job like a person, and call the rotation link from the dashboard between batches rather than between requests.
  • Use the socks5h scheme so DNS lookups also happen through the SIM.
  • Set a sensible timeout: a rotation takes a few seconds, and requests during it will fail and should be retried.

curl

Command line

The quickest way to prove a SIM works from a terminal, and a fine tool for one-off checks and small scripts. One flag sends the request through the SIM, and the response from an IP check endpoint shows the carrier address.

  1. Run curl with the -x flag and the proxy URL: -x http://USERNAME:PASSWORD@HOST:PORT for HTTP, or -x socks5h://USERNAME:PASSWORD@HOST:PORT for SOCKS5.
  2. Request an IP check endpoint and read the address in the response.
  3. Add the same flag to any other curl command that should exit on the SIM.
  4. To rotate, request the rotation link from your dashboard with a plain curl call, wait a few seconds, and check the address again.
  • Put the proxy URL in an environment variable so credentials do not end up in your shell history.

What every tool needs from you

Your dashboard shows four things for each SIM: a host, a port for HTTP and a port for SOCKS5, a username and a password. That is everything any of the tools above asks for. Behind the login is one physical SIM from AT&T, T-Mobile or Verizon in one 4G or 5G device in the city you chose, used by you alone for the term. Either protocol reaches the same SIM and the same address; SOCKS5 also carries UDP, which some apps use.

The plan prices are the same whatever tool you use: 4G at $5 a day, $28 a week or $65 a month, 5G at $6, $31 or $75, with unlimited data and free moves between our cities. The month is the plan the service is built around.

Which browser we point people to

When someone asks which profile browser to use, the answer is Undetectable.io first and GoLogin second. Both isolate each profile with its own fingerprint, both attach a proxy to the profile and let you check it before launch, and both have a free plan. Undetectable.io is the easier start on Windows and Mac. GoLogin is the choice for Linux, for opening a profile from an Android phone, and for teams that share profiles.

The one rule that matters

Whatever tool you pick, keep one SIM per identity and keep the pair together for the month. Set the device or profile's time zone and language to the SIM's city, disable WebRTC leaks in browsers, and rotate the SIM only between sessions. A proxy changes the network path and nothing else, so run only the accounts you are entitled to run and follow each platform's rules. If a tool will not connect, email [email protected] or message @SimProxiesBot and a person will look at the line from our side.

Integration questions

Which profile browser should I start with?

Undetectable.io. If it does not fit how you work, GoLogin is the other one we recommend. Both take a SimProxies SIM in a couple of minutes.

HTTP or SOCKS5?

Whichever the tool handles best. Both reach the same SIM and the same address. SOCKS5 also carries UDP, and the socks5h scheme sends DNS through the SIM too.

Can one SIM serve a browser profile and a script at once?

Within the line's connection limit, yes, and both will appear from the same address. Do it only if they should look like one person; otherwise rent a second SIM.

Every tool here takes a standard proxy

HTTP and SOCKS5 ports, username and password, on a dedicated US carrier line. Plans from $2 for 2 hours or $5/day.
