Undetectable.io with Premium Dedicated Mobile Proxies

Undetectable.io is the antidetect browser we point EliteProx customers to first. It runs on Windows and macOS, gives every profile its own fingerprint and its own proxy, and lets you keep profiles either on your own machine or in the cloud so you can open them from another computer. That covers the device half of a clean identity. The network half is where a premium, dedicated line earns its keep: one modem, one SIM on a major US carrier, and an IP that nobody else touches. This guide is written for people who care about getting that pairing exactly right, from the first profile on the free plan to a team running a full roster of client accounts on private carrier lines.

Why a dedicated line suits Undetectable.io

An antidetect profile is only as believable as the connection underneath it. Undetectable.io can present a consistent browser and device, but if the IP below it is shared with strangers, the history of that address arrives with every login. A dedicated EliteProx line removes that unknown. The modem sits in our own rack, the SIM is on AT&T, T-Mobile or Verizon, and the only traffic leaving through it is yours.

Carrier IPs also carry a quiet advantage. Mobile networks put many ordinary phones behind a small range of addresses, so services are used to seeing real people arrive from them. When a profile with a coherent fingerprint shows up on such an address, with a timezone and language that match its city, nothing about the session looks out of place.

• One modem and one SIM per line, never pooled with other customers
• Real AT&T, T-Mobile or Verizon addresses rather than hosting ranges
• HTTP and SOCKS5 ports on every line, both with username and password
• The IP stays put until you decide to rotate it

Local or cloud profiles: choosing where identities live

Undetectable.io offers two homes for a profile. Local profiles are stored on your own device, which suits a single operator who wants everything on one workstation. Cloud profiles can be opened from other devices, which suits anyone who moves between an office machine and a laptop, or who hands work to a colleague. The free plan lets you start with up to five cloud profiles, and paid plans raise the ceiling when the roster grows.

Whichever you choose, the proxy travels with the profile. That is the property that matters most to a premium setup: a client identity opened on Tuesday from the office and on Thursday from a hotel still leaves through the same dedicated carrier line, so the account sees one consistent phone network rather than two different places.

Attaching an EliteProx line to a profile

Everything you need is on the proxy's row in the EliteProx dashboard. The steps below assume a new profile, but editing an existing one works the same way.

If the check fails, the cause is almost always a stray space in a pasted value or a port that belongs to the other protocol. Fix it and test again before launching; a profile that has never seen the wrong network is easier to keep clean than one that has.

1. Open your EliteProx dashboard and pick the line you want to dedicate to this identity. Note the host, the SOCKS5 port, the HTTP port, the username and the password.
2. In Undetectable.io, create a new profile and choose whether it should be local or cloud.
3. In the profile's proxy settings, select SOCKS5 (our default suggestion) or HTTP, then enter the host, the matching port, the login and the password.
4. Run the proxy check. Confirm the reported IP belongs to a US carrier and that the city is the metro you ordered.
5. Let the profile's timezone, language and geolocation follow the proxy IP, and set WebRTC to use the proxy's address.
6. Save, launch the profile, and open an IP lookup page inside it to confirm the browser sees the same address the check reported.

Sticky sessions and when to rotate

Every EliteProx line is sticky by default. For account work that is exactly what you want: sign in, do the day's tasks on one address, sign out. A session that jumps to a new IP halfway through looks unlike any real handset and invites extra verification.

When you do want a fresh address, use the rotation link on the line's row in the dashboard, or call it from a script or our API. There is no wait between changes and rotations are unlimited. Rotate with the profile closed, then reopen it so the browser picks up the new IP from a clean start. For research tasks, a simple rhythm works well: check, close, rotate, reopen.

Running a client roster with a team

The rule that protects a premium setup is one dedicated line per profile, or at most one line per tight group of accounts that belong together. Name each Undetectable.io profile after the line it uses, with client, city and a number, and give the line the same label in our dashboard. Anyone opening either side can see the pairing immediately.

On the bigger Undetectable.io plans, profiles can be shared with team members, and paid plans add proxy import so a list of lines can be loaded in one go instead of typed one by one. Sharing the profile is far better than sharing credentials: the colleague opens the identity with its line already attached, and the password stays inside the profile.

When a client changes region, use the free self-service location move in your dashboard. The line keeps its entry and credentials; only the host and city change. Run the proxy check in the profile afterwards so timezone and geolocation regenerate from the new address.

• Match profile names to line labels so pairings are obvious
• Share profiles, not passwords, on plans that support teams
• Import a list of lines on paid plans instead of typing each one
• Re-run the proxy check after any location move

When something does not look right

A profile that opens but loads nothing usually has DNS or IPv6 traffic going around the proxy. Switching that profile to SOCKS5 sends lookups through the tunnel and resolves most of these cases. If a site shows the wrong city, the timezone was probably set by hand before the proxy was attached; let the IP drive it and restart the profile.

An unexpected sign-out on a logged-in account is worth a moment of detective work. Look for a scheduled script or a teammate who opened the rotation link while the profile was in use. Keeping rotations strictly between sessions closes that gap, and priority support is there if a line itself seems unwell.
