The setup, in order
- 1Create the browser window and open its proxy configuration before first launch.
- 2Choose a custom proxy rather than any built-in or bundled option.
- 3Set the protocol to SOCKS5 or HTTP and enter host, port, username and password.
- 4Use the proxy check and read the returned IP and country rather than only the success indicator.
- 5Launch the window, load an IP-reporting site first, and confirm the address reports as mobile.
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
BitBrowser supports HTTP and SOCKS5, and typically SSH as well. Use SOCKS5 with a mobile proxy so DNS goes out over the carrier connection. On a PocketProxy device HTTP and SOCKS5 are both live on the same connection, so this is a preference rather than a purchase decision.
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.
Per-window means per-window
BitBrowser's model is a proxy attached to a browser window rather than to a stored account. That's convenient, and it means duplicating a window can carry the proxy configuration with it.
Duplicating a window to save setup time is how two accounts end up behind one carrier IP without anybody deciding to do that. If you duplicate, change the proxy on the copy before you log anything into it.
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 BitBrowser support mobile proxies?
Yes. BitBrowser takes a mobile proxy as a standard custom proxy, needing host, port, username, password and a protocol. There's no separate mobile mode, and a carrier IP behaves like any other address from the browser's side.
Which protocol should you use in BitBrowser?
SOCKS5 as the default, because it hands DNS resolution to the proxy so lookups leave over the carrier connection rather than yours. HTTP is a fine fallback if a specific window misbehaves, and switching is a one-field change.
Can you copy a BitBrowser window and keep the proxy?
You can, and that's precisely the risk. A duplicated window can carry the same proxy configuration, which quietly puts two accounts on one carrier address. Change the proxy on the copy before logging into it.
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 BitBrowser 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.
