On Android, kill switch behavior is mainly about using the operating system's own always-on VPN controls correctly. This page explains what NimbusVPN supports, where to enable it, and when stricter blocking is worth the tradeoff.

Kill switch is most useful when the risk is not theoretical. It matters on unstable mobile data, weak public Wi-Fi, or any situation where the device might silently fall back to an open connection.
The tradeoff is stricter behavior during drops. That is useful for privacy-sensitive workflows, but some users may prefer not to block everything unless they really need that level of control.
Go to the Android network settings, open the VPN list, and select the NimbusVPN entry.
Turn on Always-on VPN first so Android treats the NimbusVPN tunnel as the default protected path.
Use block-without-VPN when you want stricter leak prevention during drops and are comfortable with traffic being blocked until the tunnel is back.
Useful when Android frequently moves between Wi-Fi and mobile data and you do not want traffic silently escaping the VPN during the transition.
Helpful in cafes, airports, or hotels where captive portals and unstable sessions can kick the device back onto an open connection.
Makes sense when the user prefers temporary blocking over any chance of unprotected traffic during reconnects.
Yes. NimbusVPN relies on Android's native always-on VPN and block-without-VPN controls, which is the most predictable way to get kill switch behavior on Android devices.
Enable it in the Android VPN settings for NimbusVPN by turning on 'Always-on VPN' and then 'Block connections without VPN' if you want stricter blocking during disconnects.
It helps prevent accidental fallback to an open connection, but users should still validate their setup after enabling Android's always-on and block-without-VPN options.
Using the operating system's own always-on VPN controls is typically more predictable than shipping a custom user-space workaround for leak protection.
Absolutely not. NimbusVPN is designed as a true VPN with no account required, meaning you can start using it immediately after installation. We never ask for your email, phone number, passwords, or any personal details, ensuring your complete anonymity and peace of mind online.
NimbusVPN utilizes highly secure and modern open-source protocols, specifically XRay/VLESS and WireGuard. These advanced technologies are carefully chosen for their exceptional performance. They ensure you maintain a stable, fast, and secure connection even when browsing on unstable, restrictive, or heavily censored internet networks worldwide.
Yes, you have complete control over your network traffic. Our advanced split tunneling feature lets you select exactly which apps route through the protective VPN tunnel, and which apps continue using your regular, unencrypted internet connection. This is perfect for accessing local banking apps or smart home devices.
