How to Use the UCSS VPN App on Windows

Once you're signed in, using the UCSS app on Windows is straightforward.
First, click the server selection button in the bottom-right corner of the app to choose the VPN server you want to connect to.

Choose a VPN server location based on the websites or services you want to access.
For example:
- Choose a UK server for websites and services available in the UK.
- Choose a US server for websites and services available in the US.
- Choose an Australian server for websites and services available in Australia.
How to Choose a UCSS Server

UCSS offers several types of servers, each optimized for different use cases.
- Japan Edge CN Server: Optimized for accessing Chinese services from outside mainland China.
- GA (2× Rate) Server: Designed for low-latency connections and reduced packet loss. These servers consume data at twice the normal rate, but their low ping makes them particularly useful for latency-sensitive activities such as online gaming. GA servers are one of UCSS's notable features.
- East Europe Edge Server: Optimized for connections from Russia and nearby regions.
The websites and services you can access may vary depending on the server you're connected to. Connection speeds can also vary depending on how busy each server is.
If you're unable to connect to a service or the connection feels slow, try switching to a different server.
How to Choose a UCSS Connection Mode

Click the menu button in the top-left corner of the app.
Click “Mode.”

The best UCSS connection mode depends on how you use the service.
- Global: Suitable for Global plan users, as well as those who use UCSS for gaming or prefer to route all of their traffic through UCSS servers. This mode can be used both inside and outside China.
- Smart Routing: Designed for users in China who also need access to Chinese apps and services. Traffic to non-Chinese IP addresses is routed through UCSS servers, while traffic to Chinese IP addresses is handled separately.
- Browser: Suitable if you only need to use UCSS in a web browser. Web browser traffic is routed through UCSS servers.
If routing all of your traffic through UCSS isn't a priority, choose the mode that best fits how you use the service.

Once you've selected a server and connection mode, click the button in the center of the app to connect to the VPN.
Once the app shows that the connection is successful, UCSS is connected and the VPN is ready to use.
To disconnect from the VPN, click the button in the center of the app again.
Using a VPN can sometimes reduce your internet speed because your traffic has to pass through an additional VPN server. If you don't need the VPN, you can disconnect and reconnect whenever necessary.
