The setup, in order
- 1Decide whether the profile runs locally or in the cloud before configuring the proxy, because that decides where the connection originates.
- 2Open the profile's proxy configuration and choose a custom proxy.
- 3Set SOCKS5 or HTTP, then enter host, port, username and password.
- 4Run the proxy check and read the exit IP and country it returns.
- 5Launch the profile and load an IP-reporting site as the first request it makes.
Menu names in these tools change between releases, so the steps above name the field rather than the button. If a label has moved, the values it wants haven't.
Which protocol to pick
NSTBrowser takes HTTP and SOCKS5. Use SOCKS5 so DNS resolves through the carrier connection. Both are simultaneously available on a PocketProxy device, so you can change your mind per profile without buying anything different.
One protocol trap worth knowing across all of these: Chromium doesn't support SOCKS5 with a username and password. Anything Chromium-based that talks to the proxy outside the browser's own profile handling, including most scripted setups, wants the HTTP endpoint instead. More in SOCKS5 vs HTTP.
Cloud profiles connect from the cloud, not from you
This is the one genuinely NSTBrowser-specific thing worth knowing. A cloud profile's connection to your proxy originates from NSTBrowser's infrastructure rather than your machine.
If your proxy is locked to an IP allowlist rather than a username and password, a cloud profile will fail while the identical local profile works, and the failure looks like bad credentials. Either use username and password authentication for cloud profiles, or allowlist the right addresses. Diagnose by running the same profile locally: if it works there and not in the cloud, this is why.
Three things that decide whether it holds
These apply whichever browser you run, and they matter more than any setting inside it.
One profile, one proxy, permanently
The pairing is the point. A profile that logs in from one carrier IP for a month and then appears on a different one has told the platform more than any fingerprint setting can hide. Assign the proxy when you create the profile and leave it alone.
Match the timezone and locale to the exit IP
Every one of these browsers lets you set timezone, locale and WebRTC handling per profile, and most will offer to derive them from the proxy's IP. Take that offer. A US carrier IP reporting a European timezone is a mismatch that costs nothing to avoid.
Verify the exit IP before you log in, not after
Open the profile and load any IP-reporting site first. You're checking two things: that the address is the one you expect, and that it reports as mobile rather than hosting. Doing this after a login attempt means the first thing the platform saw was whatever was leaking instead.
Frequently asked questions
Does NSTBrowser work with mobile proxies?
Yes, for both local and cloud profiles. It takes the standard host, port, username, password and protocol, and a carrier IP needs no special handling inside the browser.
Why does an NSTBrowser cloud profile fail when the local one works?
Because the cloud profile reaches your proxy from NSTBrowser's infrastructure, not from your machine. If the proxy authorises by IP allowlist rather than credentials, the cloud address isn't on the list. Switch that connection to username and password authentication, or allowlist appropriately.
Should you run profiles locally or in the cloud with a mobile proxy?
Locally is simpler, because the connection comes from where you are and IP-based authorisation keeps working. Cloud profiles are useful for uptime without leaving a machine running, but they add a hop and they change which address your proxy sees connecting.
Setting up a different browser? The antidetect browser proxy hub covers the rest, and running multiple accounts without bans covers the parts no browser setting can fix.
A carrier IP to point NSTBrowser at
Every PocketProxy is one real Android phone on a real carrier, with HTTP and SOCKS5 live at once and rotation on demand. The trial is 48 hours and takes no card.
