Apps That Take a Real US SIM Line, With the Settings and the Proof Step
A SIM line from Real US Proxies is handed to software in one of two forms: the host, two ports and login printed on the line's card at mine.realusproxies.com, or, on server-based lines, the card's VLESS link for apps that carry a whole device. Below are the apps our customers use most, chosen with buyers in China and Vietnam in mind, since several of them are already on those buyers' phones. Each entry has the settings that matter and ends with the same step: open an IP checker through the app and confirm the carrier, the cellular type and the state before the app touches anything that matters.
Undetectable.io
Antidetect browser, Windows and MacOur first recommendation for keeping US accounts apart: each profile carries its own fingerprint, storage and proxy, and the browser's own check names the carrier and city before a profile opens a site. Profiles can be local or synced for a team.
- In the proxy manager, add a SOCKS5 entry with the host, SOCKS5 port and login from the line's card, named for the SIM's city and carrier.
- Press the entry's check and read United States, the carrier, and a city in the SIM's state.
- Create a profile for the account, pick its operating system, attach the saved entry.
- Let time zone and geolocation follow the proxy; set language to en-US.
- Launch, open an IP checker, confirm carrier, cellular and state, and screenshot it.
- One account per SIM is the simplest rule; profiles that share a SIM share its address.
- Edit the saved entry once after a city move and every profile follows.
GoLogin
Antidetect browser, Windows, Mac, Linux, AndroidOur second recommendation and the one for teams and Linux: profiles live in GoLogin's cloud with their proxy and open from any desktop or the Android app, so a storefront can be checked from a phone at night on the same SIM used at a desk by day.
- Create a profile and keep the generated fingerprint for the operating system you want.
- In the Proxy tab choose SOCKS5 and paste the host:port:username:password string copied from the line's card.
- Press Check proxy and read the US flag, the carrier and a city in the SIM's state.
- Keep time zone and geolocation on Based on IP, set language to en-US, save.
- Launch, open an IP checker, confirm carrier, cellular and state, and add the screenshot to the profile's notes.
- One folder per SIM, named for its city, keeps a team organised.
- Opening a profile from the Android app routes the phone through the same SIM.
v2rayNG
VLESS client, AndroidThe Android client many of our buyers already have installed. It imports the line's vless:// link from the clipboard and carries the whole phone, or selected apps, through the SIM.
- Copy the VLESS link from the line's card.
- In v2rayNG tap the plus sign and choose import from clipboard.
- Select the server and tap connect.
- Open an IP checker in the phone's browser and confirm the carrier, cellular type and state.
- Screenshot the result.
- Use per-app routing so only the apps that should be in the US go through the SIM.
- The link does not change on rotation; the app reconnects by itself.
Hiddify
VLESS client, Android, Windows, macOS, LinuxAn open-source Xray-family client with a simple interface on every platform. It imports the vless:// link and puts the whole device on the SIM, with per-app rules on Android.
- Copy the VLESS link from the line's card.
- In Hiddify choose Add profile, then paste the link.
- Connect, open an IP checker in a browser on the device, and confirm the carrier, cellular type and state.
- Screenshot the result.
- Keep the link private and reissue it from the dashboard if it may have been shared.
- On a laptop, Hiddify is the quickest way to put every application on the SIM at once.
Shadowrocket
VLESS client, iOSThe usual iPhone and iPad client for the Xray family. It imports the line's vless:// link and routes the device through the SIM, with per-app and per-domain rules.
- Copy the VLESS link from the line's card.
- In Shadowrocket tap Add Server and paste the link.
- Connect, open an IP checker in Safari and confirm the carrier, cellular type and state.
- Screenshot the result.
- Set global routing to Proxy for a whole-device check, or add rules for US apps only.
- Storefront and marketplace apps opened through Shadowrocket show the SIM's address.
Clash
Rule-based client, Windows, macOS, AndroidClash-family clients, such as Clash Verge and Clash Meta, are common among buyers in China and route traffic by rules. The SIM can be added as a SOCKS5 or HTTP proxy node or through its VLESS link, and rules decide which sites use it.
- Add a proxy node of type socks5 with the host, SOCKS5 port and login from the line's card, or import the VLESS link as a node.
- Create a rule group that sends the US sites you work with to that node and everything else direct.
- Enable the configuration and open an IP checker through a site in the rule group.
- Confirm the carrier, cellular type and state and screenshot it.
- Rules let local sites stay fast while US accounts run on the SIM.
- Name the node for the SIM's city so rule files stay readable.
Proxifier
System proxy, Windows and macOSProxifier sends chosen applications, or the whole computer, through a SOCKS5 or HTTP proxy without the applications knowing. It is the way to put a desktop app with no proxy setting, such as a seller tool, onto the SIM.
- Add a proxy server with the host, SOCKS5 port and login from the line's card.
- Create a rule that sends the chosen applications, or all applications, through it.
- Enable name resolution through the proxy so DNS leaves through the SIM.
- Open an IP checker from a routed application and confirm the carrier, cellular type and state.
- Route only the applications that should be in the US; leave messaging and local tools direct.
- Proxifier does not change a browser's fingerprint; use a profile browser for accounts.
Android Wi-Fi proxy settings
Built-in, AndroidAndroid can send a Wi-Fi network's browser traffic through an HTTP proxy with no app installed, which is the fastest way to look at a storefront from a phone on the SIM. Apps that ignore the system proxy need the VLESS route instead.
- Open the Wi-Fi network's settings, choose Modify, and set the proxy to Manual.
- Enter the line's host and HTTP port; enter the login when the browser asks.
- Open an IP checker in Chrome and confirm the carrier, cellular type and state.
- Screenshot the result.
- The setting is per Wi-Fi network; remove it when the check is done.
- For apps rather than the browser, use v2rayNG or Hiddify with the VLESS link.
Python requests
ScriptsFor scripts that check listings, prices or orders through the SIM at a human pace. The socks extra lets requests use the SOCKS5 port with DNS resolved inside the SIM.
- Install requests with the socks extra.
- Set the proxies mapping to socks5h://username:password@host:port for both http and https.
- Request an IP lookup endpoint first and assert the carrier and country in the reply.
- Keep the request pace within the target site's rules and call the rotation link between batches if needed.
- socks5h, not socks5, so DNS lookups leave through the SIM too.
- A script that respects a site's pace needs only the 4G tier.
curl
Command lineThe quickest proof from a terminal that the SIM is live and real: one command through the SOCKS5 port against an IP lookup endpoint returns the carrier, type and country.
- Run curl with -x socks5h://username:password@host:port against an IP lookup endpoint that returns JSON.
- Read the organisation, connection type and country in the output.
- Call the rotation link with curl and repeat; the carrier and state should be unchanged.
- Save the output with a timestamp; it is the same proof as a checker screenshot in text form.
- Use -v to see the SOCKS handshake if the connection fails.
The two settings that are always yours
Whatever the app, the SIM supplies the address and nothing more. The clock and the language are set in the app or the device, and they should match the SIM's city, Eastern for New York, Boston, Miami and North Carolina, Central for Chicago and Houston, Mountain for Phoenix, Pacific for Los Angeles, with US English as the language. A SIM in Houston under a browser reporting Asia/Shanghai is a contradiction a platform can see; the address alone cannot fix it.
Which form of the line to give each app
Browsers, profile managers and scripts take the proxy form: SOCKS5 where offered, since it carries every protocol and keeps DNS inside the SIM, otherwise HTTP. Phones, and any network where raw proxy connections are unreliable, take the VLESS link through an Xray-family client, which many buyers in China and Vietnam already run for other purposes. Both forms exit on the same SIM and show the same carrier in a checker.
Rotation and city moves across apps
Rotating the SIM changes its public address and nothing in any app: proxy apps reconnect on the next request, VLESS clients reconnect on their own. Rotate with browser profiles closed. A free move to another city keeps the login in most cases; update the stored proxy once if the host changes, and update the clock setting to the new city at the same time.
Integration questions
Which app should a buyer in China or Vietnam start with?
v2rayNG or Hiddify on the phone with the VLESS link, since most buyers already use them, and Undetectable.io on the computer for accounts.
Do the proxy ports and the VLESS link share a login?
The HTTP and SOCKS5 ports share one username and password. The VLESS link carries its own identity inside the link.
Can several apps use one SIM at the same time?
Yes, up to the line's connection limit; they all show the same carrier address. Keep unrelated accounts on separate SIMs.
How do I prove the app is really on the SIM?
Open an IP checker through the app and read the carrier in the ISP field, cellular as the type and the SIM's state as the region. Screenshot it.
