Our service does not limit speed or bandwidth. The actual speed depends on your device's current local network connection quality.

Global Mode means all traffic from the app goes through JumperVPN servers, whether you're accessing domestic or international websites — everything routes through JumperVPN.

Smart Mode means only international website traffic goes through JumperVPN servers, while domestic website traffic still uses your local network (WiFi or 4G), which helps optimize access speed.

If the server speed is abnormal, you can first try switching to a different server. When switching servers, we recommend disconnecting and reconnecting, as direct switches may encounter latency issues. If switching servers doesn't help, it's likely a local network issue. You can try restarting your router or switching to a different network or hotspot.

You can reliably access AI services using servers in the United States, Japan, Singapore, South Korea, Germany, and other locations. We recommend disconnecting and reconnecting when switching servers, as direct switches may have latency issues.

We use our proprietary encryption protocol, not the standard public protocols, and your IP address is hidden throughout your entire session. We promise not to keep any user browsing history or activity logs. From a security perspective, we guarantee the privacy and security of your IP address, website browsing, and data communications.
