Undetectable.io Profiles on a New York Mobile Proxy

Undetectable.io is the browser we point customers to first when they want separate profiles that do not leak into each other. Pairing a profile with a dedicated New York carrier line is simple, but there are four or five places where people get it slightly wrong and then blame the proxy. This is the setup we use ourselves when we test a line from a desktop, written out so you can follow it in ten minutes.

Before you open the browser

Order the line first. From the dashboard at nyc.newyorkproxies.com pick Verizon or AT&T, 4G or 5G, and a term. An hourly test is enough to validate the setup. When the line activates, the dashboard shows a host, a port for HTTP and a port for SOCKS5, a username and a password. Copy them somewhere handy. Also note the rotation link, which is a URL you can open to get a new address.

Decide now whether this profile should keep one address for a long time or change often. For a profile that logs into an account, keep it sticky and do not touch the rotation link while the browser is open. For research profiles that just read pages, rotating between sessions is fine.

Creating the profile

Open Undetectable.io and create a new profile. Give it a name that includes the line, something like NYC-VZ-01, so you never attach two profiles to the same line by accident. Pick the operating system to match the machine you are on; mixing a Windows fingerprint with a Mac host is a detectable oddity that has nothing to do with the proxy.

In the proxy section choose the protocol. We suggest SOCKS5 because it carries DNS through the tunnel, so name lookups leave through the carrier too. Enter the host, the SOCKS5 port, the username and the password from your dashboard. Use the built-in check button; it should come back with a New York location and a carrier name. If it shows anything else, re-check the port, since HTTP and SOCKS5 use different ones.

Matching the rest of the profile to New York

The proxy gives you a New York carrier address. The profile has to agree with it. Set the time zone to America/New_York, or let the browser derive it from the IP if that option is offered. Set the language to en-US. If the profile offers geolocation, let it follow the IP rather than entering coordinates by hand; an exact pin in Brooklyn next to an IP that geolocates to Manhattan is the kind of mismatch nobody needs. WebRTC should be set to use the proxy or be disabled so your home address never appears in a media negotiation.

• Time zone: America/New_York
• Language: en-US
• Geolocation: follow the IP
• WebRTC: through proxy or off
• DNS: through SOCKS5

The first launch and what to check

Start the profile and open a what-is-my-ip page. Confirm the address belongs to the carrier you ordered and reads as New York. Open a WebRTC leak test and confirm only the proxy address appears. Open a page that shows your browser's reported time and confirm it is Eastern. Three tabs, two minutes, and you know the profile is clean before any account ever sees it.

Then browse like a person for a few minutes. Read a news site, search something, scroll. A profile that goes straight from creation to a login form is doing something no real New Yorker does.

Rotating without wrecking the profile

If you need a fresh address for this profile, close the profile first, open the rotation link or press rotate in the dashboard, wait for the dashboard to show the new address, then relaunch. Rotating while the profile is open mid-session drops its connections and some sites notice a login that moved address in the middle of a page. There is no waiting period between rotations on our side, so the only pause is the modem re-registering, usually well under a minute.

For scripted work, Undetectable.io exposes a local API that can start and stop profiles, and our dashboard exposes a rotation URL. A small script that stops the profile, calls the URL, polls our API until the address changes, and starts the profile again is all most people need.

Several profiles, several lines

One profile per line is the rule we recommend. Two profiles sharing a line share an address, which is fine for research but a bad idea for two accounts that are supposed to be unrelated. If you run several accounts you are entitled to run, give each its own line, ideally spreading them across Verizon and AT&T so a carrier-side hiccup never affects all of them at once. Lines are $5 a day on 4G or $65 a month, so a handful of them is not a large bill.

And the obvious reminder: use profiles only for accounts and sites you are allowed to use, and follow each platform's rules. The browser and the line make a clean, consistent New York session; what you do inside it is on you.
