How to Set Up a Mobile Proxy in Multilogin

Multilogin is one of the most established antidetect browsers, used heavily by affiliate marketers, media buyers, and anyone managing multiple browser profiles at scale. Like any antidetect browser, the proxy you pair it with makes or breaks the setup.

This guide walks through exactly how to set up a SentraCell 4G/5G mobile proxy in Multilogin using SOCKS5, verify that it is working, and use your rotation link to get a fresh IP whenever you need one.

What You'll Need

• -Multilogin installed and logged in
• -SOCKS5 credentials (host, port, username, password) from your SentraCell DM
• -Rotation link for rotating your IP on demand, included with every port

Step-by-Step Setup

• 1
  Open Multilogin and click Create to start a new browser profile. Name it whatever you want.
• 2
  Click Proxy in the profile settings, then select Custom.
• 3
  Select SOCKS5 as the proxy type. HTTP works too, but SOCKS5 is what we recommend.
• 4
  Get your proxy credentials. Open Telegram, go to the SentraCell bot, tap Credentials, and copy your SOCKS5 login string.
• 5
  Paste the credentials into Multilogin: host, port, username, and password in their fields. Give it a moment to connect.
• 6
  Check the connection. Multilogin pings the proxy automatically. Once it shows a successful connection, you are good.
• 7
  Click Create to save the profile, then launch the browser.
• 8
  Verify the proxy is active at browserleaks.com/ip or any IP checker. You should see the proxy's carrier location, not your real one.

How to Rotate Your IP

Every SentraCell proxy includes a rotation link, and you can use it directly from inside the Multilogin browser. Paste the rotation link into the address bar and hit enter. The device pulls a fresh carrier IP in about 5 to 10 seconds. Refresh your IP checker to confirm the change.

Why Mobile Proxies Work Better in Antidetect Browsers

Antidetect browsers solve the browser fingerprint problem by making each profile look like a unique device. But if all your profiles share the same datacenter IP, platforms can still link them together at the network level.

Pairing Multilogin with a real mobile proxy solves both sides. The browser fingerprint looks unique, and the IP looks like a genuine mobile user on Verizon, AT&T, or T-Mobile. No datacenter flag, no shared IP pool, and no connection between your profiles at the network level.

That is the combination that actually works at scale.
