The split mode feature in Pro NPV for China is compatible with web applications such as Telegram, WhatsApp, and Gmail, which use HTTPS. This mode can modify the routing for both HTTP (port 80) and HTTPS (port 443), allowing access to the web versions of these applications. However, the app versions may utilize different ports.

To guarantee access, the following actions should be taken:

• Activate the "Global Mode" option found in the routing settings.
• Adjust the proxy settings of the application. For instance, here is how you can update the proxy settings for the LINE app:
  
  

• Should you try to sign in on a new device and go beyond the device limit, you will be redirected to the "Unbind Device" page, allowing you to remove any linked devices.
• Additionally, you can go to "Menu" > "App Settings" > "Device List" to choose and unbind a device that you prefer.

Forgetting usernames or passwords is a frequent occurrence, and we strive to simplify the recovery process. Here are your options:

• If you've forgotten your username, please reach out to us and include a screenshot of your payment confirmation.
• If you can't remember your password, simply utilize the "forgot password" option found in the app.

We've observed that some users find it challenging to select a server after choosing a region.

To make things easier, we now only show regions. Heibao will automatically connect you to the server with the best performance in your selected region. Here are the details:

• The location menu will display only regions, but each region includes hundreds of servers. When you choose a region, Heibao automatically connects you to the server that provides the best performance according to your network conditions.
• If you're unhappy with the server you're connected to, you can disconnect and reconnect to the same region to be assigned to a different server.
• You can repeat this process until you discover a server that suits your requirements.

Common reasons for network problems include:

• Slow local internet speeds (when not using a NPV)
• High user activity at specific NPV server locations

To fix these issues, you can attempt the following strategies:

• Verify your local internet speed by disabling the NPV temporarily
• Experiment with various network connections like WiFi, 4G, or 5G with the NPV turned off to detect any connection issues. For instance, if your WiFi is inconsistent, try switching to a mobile data connection.
• Disable the NPV, select a different server location, and then reconnect
• If you wish to remain connected to the same geographic area, disconnect and reconnect, as this may connect you to a different server within the same region.
• Keep testing until you locate the best server for your needs.

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

Split Mode: This option utilizes NPV exclusively for websites that are restricted due to geographical limitations, such as Google, YouTube, and Netflix, while preserving access to local networks for Chinese sites.

You can modify the routing mode in the App Settings.

If you encounter issues accessing specific websites or applications, consider switching to "Global Mode."
