Set up a 4G proxy in Octo Browser

Why a 4G proxy in Octo Browser?

Octo Browser isolates each profile: cookies, browser fingerprint, time zone. The IP address, though, comes from the proxy you attach to the profile. With a ShadowProxy 4G proxy, websites see the IP of a French mobile subscriber, just like an ordinary smartphone on 4G.

Each proxy is a physical modem with its own SIM card, reserved for a single customer. The IP stays the same until you change it, which keeps your profiles consistent from one session to the next.

This guide shows where the proxy setting is in Octo Browser, which fields to fill in with your ShadowProxy details, how to check the connection and how to change IP. The general method, valid for every multi-profile browser, is in our anti-detect browser guide.

1. Get your ShadowProxy access details

In your customer area, open 4G proxies then your proxy. You will find two lines, in the format address:port:username:password:

HTTP    proxy.shadowproxy.fr:10001:username:password
SOCKS5  proxy.shadowproxy.fr:20001:username:password

The HTTP port starts with 1 (100xx), the SOCKS5 port with 2 (200xx). Both go out through the same modem and the same IP.

2. Add the proxy to the Octo Browser profile

1. Create a profile or open it for editing. Quick edit is enough to change the connection of an existing profile.
2. In the Proxy / VPN field (by default “Set proxy / VPN”), add a new proxy.
3. Paste your line in the format ip:port:login:password, for example proxy.shadowproxy.fr:20001:username:password, with the SOCKS5 or HTTP protocol. Octo Browser also accepts the protocol at the start of the line.
4. To reuse this proxy on other profiles, tick Save to the Proxy Manager and give it a name.

If the profile is running while you edit it, the new proxy applies the next time the profile starts. You can also attach the proxy to a profile template: profiles created from that template use it directly.

3. Check the connection

Before saving, click Check proxy. The IP shown should be French and match the one in your customer area.

4. Match the time zone and language

A French IP with a time zone or language from another country is an inconsistency that websites notice. In the Octo Browser profile, let the time zone and geolocation follow the proxy IP, or set them to Europe/Paris, and choose a language consistent with a user in France.

5. Change IP whenever you want

From your customer area, with the Change IP button, or by opening your personal rotation link (on the proxy page): a single call is enough, from a browser or a script. The new address is active in under 20 seconds. No need to edit the Octo Browser profile: the host and port stay the same, only the exit IP changes.

Good practice

• One proxy per profile or per small group of related profiles (one client, one project), so unrelated accounts are not linked together.
• SOCKS5 preferably, HTTP if a tool does not support SOCKS5: both go out through the same IP.
• Do not change IP in the middle of a signed-in session: do it between two sessions.
• Respect the terms of use of the sites you use.
