The split mode feature in Yunfan NPV for China is compatible with web applications such as Telegram, WhatsApp, and Gmail that make use of HTTPS. This mode can change the routing for both HTTP (port 80) and HTTPS (port 443), allowing access to the web versions of these applications. Nevertheless, the application versions might operate on different ports.

To guarantee access, the following steps should be taken:

• Enable the "Global Mode" option found in the routing settings.
• Adjust the application's proxy settings. For instance, here's how to modify the proxy settings for the LINE app:
  
  

• Should you try to log in on a new device and surpass the device limit, you will be directed to the "Unbind Device" page, where you can disconnect any linked devices.
• Additionally, you can go to "Menu" > "App Settings" > "Device List" to choose and unbind a device you prefer.

We have observed that some users find it challenging to select a server after they have chosen a region.

To make the process easier, we now only show regions. Heibao will automatically connect you to the highest performing server in your selected region. Here are the details:

• The location menu will exclusively display regions, but each region includes hundreds of servers. Upon selecting a region, Heibao will automatically connect you to the server that provides the best performance according to your network conditions.
• If you are not happy with the server you are connected to, you can disconnect and then reconnect to the same region to be connected to a different server.
• You can repeat this process as many times as necessary until you find a server that suits your needs.

Frequent reasons for network problems include:

• Local slow internet speeds (without utilizing an NPV)
• Increased user traffic at specific NPV server locations

To address these issues, you can attempt the following techniques:

• Verify your local internet speed by temporarily turning off the NPV
• Experiment with various network connections like WiFi, 4G, or 5G with the NPV disabled to detect any connectivity issues. For instance, if your WiFi is inconsistent, consider switching to a mobile data connection.
• Disable the NPV, select a different server location, and then reconnect
• If you prefer to remain connected to the same geographical area, disconnect and reconnect, as this may connect you to a different server within the same region.
• Carry on with these tests until you discover the most suitable server for your needs.

Global Mode: This option enables NPV for all online activities, which might result in slower performance for local websites and applications.

Split Mode: This mode applies NPV solely to sites that are blocked due to geographic limitations, such as Google, YouTube, and Netflix, while allowing local network access for Chinese websites.

You can modify the routing mode in the App Settings.

If you encounter difficulties accessing certain websites or applications, consider switching to "Global Mode."
