Biubiu VPN provides a free allowance that can be claimed over time, which is useful for light browsing and testing node quality. For heavy traffic, lower latency or more devices, VIP dedicated lines are the better fit.

Not necessarily. The Biubiu VPN app includes one-click connection. If you prefer v2rayN, Shadowrocket, or v2rayNG, you can also import a subscription by following the guide.

Device limits depend on your plan. The basic plan supports 3 devices, while higher tiers can support up to 10 devices online at once.

ExpressVPN, NordVPN and Surfshark are strong global products, but Biubiu VPN focuses more directly on China VPN routing, Chinese-language support, dedicated relay paths and app flows built for restrictive networks.

Update the subscription list, switch to a lower-load node, and confirm your device time is correct. If the problem continues, send the exact error or screenshot to support.

Yes. Return-to-China routes can help overseas users access NetEase Cloud Music, Youku, iQIYI and other region-limited services when available.

If the official Download VPN link is slow, contact support for a mirror address or join the official Telegram channel for the latest installer.

Yes. Routers that support OpenWrt, Merlin or Padavan firmware can be configured through compatible plugins or proxy cores.

Click 'Forgot Password' on the login page and use your registered email to receive a reset link. Keep your email available for account notices.

Yes. Whether you are on 5G, home broadband, hotel Wi-Fi or school networks, Biubiu VPN uses encrypted connections to protect traffic in transit.

Your ISP should not be able to read the specific websites or app content inside the encrypted tunnel. It may only see that an encrypted connection is active.

No. We do not log browsing history, downloaded content or real browsing trails. Only the information needed to operate accounts and service access is retained.

Biubiu VPN uses obfuscation such as Reality to make traffic resemble normal HTTPS behavior, improving stability for users who need a reliable VPN Service in restrictive environments.

The client uses modern encrypted transport and security mechanisms such as TLS 1.3 to reduce monitoring and hijacking risks on public Wi-Fi.

Under normal connected status, websites see the selected server IP rather than your local IP. Enabling kill switch protection further reduces exposure during unexpected drops.

Yes. If the VPN connection drops unexpectedly, the Kill Switch can block unencrypted traffic from continuing outside the tunnel.

DNS requests are handled through encrypted routing where supported, reducing local DNS pollution, hijacking and unwanted redirects.

No. Biubiu VPN is a privacy-focused VPN Provider, not an ad network. We do not monetize by injecting ads or selling browsing records.

That means the selected VPN node is active. You can switch between Hong Kong, Japan, the US, Singapore and other regions depending on your app or content needs.

Yes. We maintain different route groups for streaming, AI tools and selected financial platforms, making Netflix 4K, Disney+, 爱壹帆 and YouTube easier to access.

For casual Steam and overseas game access, Biubiu VPN's low-latency routes are often enough. Competitive players may still compare dedicated tools such as UU加速器, 雷神加速器 or 迅游加速器.

Some nodes allow P2P traffic. Use them only for lawful content in permitted regions, and choose nodes marked as suitable for downloads.

Dedicated capacity and load balancing reduce peak-hour congestion. If one node slows down, auto routing or manual switching usually restores speed.

Split tunneling lets local apps stay on your normal connection while Google, ChatGPT, YouTube and other global apps use the VPN tunnel.

Some routes include basic filtering rules to reduce common popups and malicious redirects, though they do not replace a dedicated browser security extension.

Yes. Connection issues, client installation, subscription sync and node selection questions can be submitted through tickets or the official Telegram group.

Use auto routing first. It considers distance, load and latency, while manual testing across Hong Kong, Japan, Singapore and US nodes can help fine-tune performance.

Yes. Log in with the same Biubiu VPN account and your plan benefits can sync across supported devices.

You can buy a temporary data top-up in the account center or upgrade to a plan better suited for frequent use.
