For some mobile plans, you can configure the operating system network signature.
OS Signature (p0f) allows you to select the operating system network signature for connections through mobile proxies.
The feature changes TCP/IP connection characteristics that passive analysis systems may use to identify the presumed operating system. p0f does not change the User-Agent, TLS fingerprint, Canvas, WebGL, or other browser parameters.
In the product card, the feature is displayed in the OS Signature block.

Available options:
- MacOS X
- Windows 7
- Windows 11
- MacOS Sequoia
- Windows
- Android 16 - Lenovo
- Android
- iOS new
- Linux
Important:
The feature is not available on all plans. Before purchasing and configuring a product, check whether the OS Signature (p0f) block is available in the selected product card.
The list of available operating systems for spoofing depends on the carrier and region.
Speed may be lower on iOS.
