Undetectable.io on a Texas Mobile Proxy: Setup, Step by Step

Undetectable.io is the profile browser we suggest first. It keeps each identity in its own container with its own fingerprint, cookies and storage, and it takes a proxy per profile, which is exactly how a dedicated Houston line is meant to be used. This is the setup we walk customers through, in order, with the things that trip people up marked plainly.

Before you open the browser

Buy a line at tx.texasproxies.com and open it in the dashboard. You need four values: the host, the port, the username and the password. Note which carrier it is and whether it is 4G or 5G, because you will want to label the profile the same way. If you have more than one profile to run, buy one line for each; sharing a single Houston line between unrelated identities is the quickest way to get them linked.

Decide on protocol. HTTP(S) is the safe default inside a browser. SOCKS5 works too and carries UDP, which matters for some web apps that use WebRTC or QUIC. Either one is fine for ordinary site work.

Adding the Houston line as a proxy

Open Undetectable.io and go to the proxy manager, which lives in the left-hand menu. Add a new proxy, choose the type (HTTP or SOCKS5), and paste the host, port, username and password from the dashboard. Give it a name you will recognise later, something like Houston ATT 4G line 1. Save it and hit the check button; the manager should report the external address and a Texas location. If it reports an error, the usual cause is a stray space in the password or the wrong protocol selected.

• Proxy type: HTTP for most sites, SOCKS5 when the app needs UDP
• Host and port: exactly as the dashboard shows them
• Login: the per-line username and password, no extra characters
• Name: carrier, generation and purpose, so you never mix lines up

Building the profile to match a Texas phone

Create a new profile and pick the saved proxy in the proxy field. Now make the rest of the profile agree with the address. Set the time zone to America/Chicago, which is Central time, or let the browser derive it from the proxy if that option is on. Set the language to English (United States). Pick a screen size that is normal for the device you are imitating, and if you choose a mobile fingerprint, use an Android or iOS user agent that matches it.

Resist the urge to randomise everything. A profile with ten unusual settings looks more unusual, not less. The goal is a boring profile from Houston, not an exotic one. Leave WebRTC set to replace or disable so the real address of your computer never leaks around the proxy, and keep geolocation on the proxy-derived setting so a site that asks for GPS gets a Texas answer.

Testing before real work

Start the profile and open two or three lookup pages. Confirm the address belongs to AT&T Mobility, T-Mobile USA or Verizon Wireless, that the location is Houston or Texas, that the time zone reported by JavaScript is Central, and that no second address appears under WebRTC. Then open the site you actually care about and browse it as a person would for a few minutes before logging in or creating anything. A warm, unhurried first session is worth more than any fingerprint setting.

Rotation inside a profile

Most profile work is sticky work: you want the same address for the whole session so that a login does not look like it jumped across town. Leave the line alone and the carrier will hold it for hours. When you do want a fresh address, between sessions rather than during one, use the rotation link from the dashboard, or the API, or set a timer. There is no wait between rotations and the profile keeps running; the next request simply leaves from a new Houston address.

If you rotate while a site has you logged in, expect the odd re-authentication. That is the site doing its job, not the proxy failing.

Running several profiles

Buy one line per profile and pin them together permanently. Spread the lines across the three carriers if you like, so that one Texas business account sits on AT&T, another on T-Mobile, a third on Verizon. Keep a plain spreadsheet of which line belongs to which profile. If a line ever needs replacing, replace it and update the one profile, not all of them. And run only accounts you are entitled to run, within each platform's rules; the browser keeps identities apart, it does not make them legitimate.
