Undetectable Browser with Mobile Proxies: Consistent Profiles

Undetectable, from undetectable.io, is an anti-detect browser that separates profiles with distinct fingerprint configurations and stores them locally or in the cloud for team use. Its proxy handling is flexible: you can add proxies to a shared list and assign them to profiles, or set a proxy directly inside a profile. What the browser cannot do is manufacture network reputation. That comes from the IP itself, and a USA 4G/5G mobile proxy provides an address that consumer phones on AT&T, T-Mobile and Verizon use every day. SpoofProxies builds its service around that reputation and around consistency, so a profile looks the same to a website on Monday as it did on Friday. Here is how to connect the two, from the proxy list to per-profile assignment, testing, timezone alignment, rotation policy and scaling.

What Undetectable needs from a proxy

Undetectable accepts a proxy type, host, port, username and password, either in the proxy section of the profile settings or in its shared proxy list from which profiles pick an entry. A check action verifies that the proxy connects and shows the external IP and its country. The browser uses that IP to set timezone and geolocation for the profile when those options are on automatic.

For a consistent profile the IP must be stable throughout a session and must resolve to a plausible location. Our mobile IPs sit in named US metros on real carrier networks, so the timezone Undetectable derives matches what the website will compute from the same address.

• HTTP(S) or SOCKS5, both included on every proxy we run
• Host, port and login credentials copied from the dashboard
• A carrier IP whose metro agrees with the profile's timezone and language
• A sticky session while the profile is in use, rotation only between sessions

Adding SpoofProxies to Undetectable step by step

Open your SpoofProxies dashboard. Each proxy lists its host, HTTP port, SOCKS5 port, username, password and rotation link. If you manage several profiles, add every proxy to Undetectable's proxy list first, naming each entry after its metro and the account it serves, then assign from the list when creating profiles.

For a single profile, create it and open the proxy section of the profile settings. Choose HTTP for straightforward browsing or SOCKS5 for UDP support and DNS inside the tunnel. Enter the host, the port for that protocol, and the username and password. Run the check and confirm a United States IP on a carrier network.

Keep timezone and geolocation on automatic so the profile follows the proxy. Save and launch. Our 4G lines typically deliver 20–45 Mbps and 5G delivers 50+ Mbps, so the profile never feels held back by the proxy.

Sticky sessions versus rotation in Undetectable

Consistency is what a website rewards. A profile that keeps the same fingerprint, cookies and IP across a session looks like one person on one phone. For any profile that signs in, run the proxy in sticky mode from open to close.

Between sessions, rotation is a normal event; phones reconnect to towers all the time. Rotations on SpoofProxies are unlimited with no wait between changes, and you can trigger them from the per-proxy rotation link or the API. Per-request rotation suits profiles that only read public pages, such as ad-verification or price-research profiles. Decide the mode per proxy and note it in the proxy list entry so account profiles never land on a rotating line.

Scaling with the proxy list and groups

Keep one proxy per unrelated account. Undetectable's proxy list makes this easy to audit: each entry should be assigned to one profile or to one small group of related profiles. Tag profiles by metro. We run modems in New York, Los Angeles, Chicago, Houston, Phoenix, Miami, North Carolina and Boston; Boston is 4G LTE only.

When a client's target region changes, use the free self-service location moves from your dashboard to move the proxy, then edit the host in the proxy list entry. Every profile assigned to that entry picks up the change. Unlimited data on every plan means long sessions and media-heavy pages do not require usage tracking.

Undetectable supports cloud profiles shared across a team and offers an API for automation. When your scripts create profiles, fetch proxy details from our API so each profile is created with a working, correctly located proxy.

Troubleshooting

If the proxy check fails to authenticate, verify the port matches the protocol. HTTP and SOCKS5 ports are different on the same host and are the most frequent source of failed checks. Strip any whitespace from the credentials.

If the timezone or coordinates do not match the IP, the profile likely has manual values left over from an earlier proxy. Return them to automatic and re-run the check. If a site reports an IP that is not the proxy, review the profile's WebRTC mode and prefer SOCKS5 so DNS also travels through the proxy.

Sudden sign-outs mean the IP changed mid-session. Look for automation that calls the rotation link and restrict it to run only when the profile is closed. If pages are slow while the check passes, see whether another tool is pushing a large download through the same proxy.

Why our carrier IPs behind Undetectable

Every SpoofProxies proxy is a real SIM card in a 4G/5G modem that we own, racked in eight US metros and connected to AT&T, T-Mobile or Verizon. Those address ranges are shared with ordinary phone users, which is where their trust comes from. Undetectable's fingerprint isolation and our carrier IPs together give a profile a coherent story at both layers.

Plans start from $6/day and run daily, weekly or monthly, with unlimited data and unlimited rotations. Each proxy includes HTTP(S) and SOCKS5 with UDP, sticky or per-request rotation, a rotation link and an API. The dashboard displays host, ports, username, password and rotation link for every proxy, ready to paste into Undetectable's proxy list.
