The split mode function in Au NPV for China accommodates web applications such as Telegram, WhatsApp, and Gmail that operate using HTTPS. This feature can modify the routing for both HTTP (port 80) and HTTPS (port 443), enabling access to the web interfaces of these apps. However, the versions of the applications may operate on different ports.

To guarantee accessibility, the following steps should be taken:

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

• In case you try to log in on a new device and surpass the device limit, you will be redirected to the "Unbind Device" page, which allows you to disconnect any linked devices.
• Alternatively, you can go to "Menu" > "App Settings" > "Device List" to choose and unlink a device you prefer.

Forgetting usernames or passwords is something many people experience, and we strive to simplify the recovery process. Here are your options:

• If you can't remember your username, reach out to us and include a screenshot of your payment receipt.

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

To make this 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 show only regions, but each region includes hundreds of servers. When you choose a region, Heibao will automatically connect you to the server that provides optimal performance based on 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 may repeat this process until you find a server that satisfies your requirements.

Frequent reasons for network problems are:

• Slow local internet speeds (without the use of an NPV)
• Increased user traffic at specific NPV server locations

To address these problems, you may want to try the following strategies:

• Monitor your local internet speed by temporarily turning off the NPV
• Experiment with various network options such as WiFi, 4G, or 5G with the NPV disabled to detect any connection issues. For instance, if your WiFi connection is unstable, consider switching to a mobile data connection.
• Disable the NPV, select a different server location, and then reconnect
• If you prefer to remain linked to the same geographical area, disconnect and reconnect, as this may connect you to another server within the same region.
• Keep testing these options until you identify the best server that meets your needs.

Global Mode: This configuration enables NPV for all online activities, which could lead to slower performance for local websites and applications.

Split Mode: In this mode, NPV is utilized solely for sites that are restricted due to geographical limitations, such as Google, YouTube, and Netflix, while still allowing access to local Chinese websites.

You can modify the routing mode in the App Settings.

If you are experiencing difficulties accessing specific websites or apps, consider switching to "Global Mode."
