Undetectable.io with Mobile Proxies: Consistent Profiles
Published · Updated
Undetectable.io is an antidetect browser for Windows and macOS that gives each profile its own fingerprint and its own proxy, and keeps profiles either locally on your device or in the cloud so you can open them from elsewhere. 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: the proxy fields, the check, timezone alignment, rotation policy, scaling across profiles and devices, and the fixes for the usual inconsistencies.
What Undetectable.io needs from a proxy
Undetectable.io takes a proxy per profile: a type (HTTP or SOCKS5), a host, a port, and a username and password. A check action verifies that the proxy connects and shows the external IP and its location. With timezone, language and geolocation set to follow the proxy IP, the profile derives all three from the address you attach.
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.io 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.io step by step
Open your SpoofProxies dashboard. Each proxy lists its host, HTTP port, SOCKS5 port, username, password and rotation link. If you would rather not use a login, whitelist your own IP there instead.
Start a new profile and go to its proxy settings. Choose HTTP for straightforward browsing or SOCKS5 to keep 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, language and geolocation following the proxy, and set WebRTC to use the proxy's IP so no second address appears. 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.
On paid plans Undetectable.io can import proxies in bulk, the tidier route once you are loading more than a few lines. Name each profile after its metro and the account it serves so the pairing stays easy to audit.
Sticky sessions versus rotation in Undetectable.io
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. Where the profile settings offer a change-IP URL field, paste the rotation link there, and reopen the profile after each rotation so it reads the new IP.
Per-request rotation suits profiles that only read public pages, such as ad-verification or price-research profiles. Decide the mode per proxy and put it in the profile name so account profiles never land on a rotating line.
Scaling across profiles and devices
Keep one proxy per unrelated account. Each line should be attached to one profile or to one small group of related profiles, and the profile names should say which. Tag profiles by metro: we run modems in New York, Los Angeles, Chicago, Houston, Phoenix, Miami, North Carolina and Boston.
When a client's target region changes, use the free self-service location moves from your dashboard to move the proxy, then update the host in each profile that uses it and re-run the check. Unlimited data on every plan means long sessions and media-heavy pages do not require usage tracking.
Local profiles stay on the device that created them; cloud profiles can be opened from other devices and, on bigger plans, shared with team members. The proxy travels with the profile, so a teammate opening a shared cloud profile exits through the same line. Avoid opening one profile on two devices at the same moment: one identity appearing twice at once is exactly the inconsistency this setup exists to prevent.
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.io
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.io's fingerprint isolation and our carrier IPs together give a profile a coherent story at both layers.
Each proxy includes HTTP(S) and SOCKS5, sticky or per-request rotation, a rotation link and an API, with unlimited rotations and no wait between changes. The dashboard displays host, ports, username, password and rotation link for every proxy, ready to paste into an Undetectable.io profile.
Get Undetectable.io, or the alternative
Undetectable.io is the antidetect browser we recommend first for SpoofProxies lines, and its free plan, with up to five cloud profiles, is enough to test everything above. If you need Linux support or phone apps, GoLogin is the alternative we suggest; it accepts the same host, port and login.
Frequently asked
Can I load many proxies into Undetectable.io at once?
Yes, on paid plans Undetectable.io supports proxy import. For a handful of profiles, entering each proxy in the profile settings is quickest. Either way, keep one line per unrelated account and name profiles by metro and account.
Which protocol keeps a profile most consistent?
SOCKS5, because DNS lookups travel through the proxy too, so nothing about the profile's network activity leaks around it. HTTP works well for standard browsing and uses the same credentials with a different port.
How do I keep a good reputation on a shared mobile IP?
Assign one proxy per unrelated account, keep sessions sticky, and do not run bulk tools through a proxy that also serves a logged-in profile. Rotate only between sessions.
Can I move a proxy to another US metro without buying a new one?
Yes. Free self-service location moves from your dashboard shift the proxy to another metro. Update the host in the Undetectable.io profile and run the check so timezone and geolocation follow the new IP.
Does a mobile proxy slow down Undetectable.io?
No. Our 5G proxies deliver 50+ Mbps and 4G typically delivers 20–45 Mbps. A browser profile uses only a fraction of that, so browsing feels like a normal connection.
