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

To guarantee access, the following steps should be taken:

• Utilize the "Global Mode" option found in the routing settings.
• Adjust the proxy settings of the application. For instance, here’s how to alter the proxy settings for the LINE app:
  
  

• If you try to log in on a new device and surpass the device limit, you will be redirected 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.

It's not unusual to forget usernames or passwords, and we strive to simplify the recovery process. Here are your options:

• If you can't remember your username, please reach out to us and send a screenshot of your payment history.
• If you can’t recall your password, simply utilize the "forgot password" option found in the app.

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

To make this easier, we now display only regions. Heibao will automatically connect you to the top-performing server within your selected region. Here are the details:

• The location menu will show only regions, but each region has hundreds of servers. Once you pick a region, Heibao will automatically connect you to the server that delivers the best performance based on your network conditions.
• If you're unhappy with the server you're connected to, you can disconnect and then reconnect to the same region to be connected to a different server.
• You can continue this process until you find a server that suits your needs.

Common reasons for network problems include:

• Slow local internet speeds (without utilizing an NPV)
• Increased user activity at specific NPV server sites

To address these problems, consider trying the following approaches:

• Verify your local internet speed by temporarily turning off the NPV
• Experiment with various network connections such as WiFi, 4G, or 5G while the NPV is disabled to identify any issues. For instance, if your WiFi connection is unstable, consider switching to mobile data.
• Disable the NPV, switch to a different server location, and reconnect
• If you prefer to remain connected to the same geographic region, disconnect and reconnect, as this might connect you to a different server within the same area.
• Continue testing until you determine the most appropriate server for your needs.

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

Split Mode: In this mode, NPV is utilized exclusively for websites that are restricted due to geographic limitations, like Google, YouTube, and Netflix, while still allowing access to local networks for Chinese sites.

You can modify the routing mode in the App Settings.

If you experience issues accessing specific websites or apps, consider switching to "Global Mode."
