The split mode functionality in Heidong NPV for China accommodates web applications such as Telegram, WhatsApp, and Gmail, all of which use HTTPS. This feature can modify the routing for both HTTP (port 80) and HTTPS (port 443), enabling access to the web versions of these applications. However, the app versions may operate on a variety of other ports.

To guarantee access, the following steps should be taken:

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

• Should you try to log in on a different device and surpass the device limit, you will be directed to the "Unbind Device" page where you can disconnect any linked devices.

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

• If you can't remember your username, please get in touch with us and send a screenshot of your payment record.

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

To streamline the experience, we now exclusively display regions. Heibao will automatically connect you to the top-performing server within your selected region. Here are the details:

• The location menu will only show regions, but each region includes hundreds of servers. When you choose a region, Heibao automatically connects you to the server that provides the optimal performance based on your network conditions.
• If you’re not happy with the server you are connected to, you can disconnect and reconnect to the same region to connect to a different server.
• You can continue this process until you find a server that suits your requirements.

Frequent reasons for network problems include:

• Slow local internet speeds (when not using a NPV)
• Increased user traffic at specific NPV server sites

To address these problems, you can try the following approaches:

• 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 pinpoint any connectivity issues. For instance, if your WiFi connection is unstable, try switching to mobile data.
• Disable the NPV, choose a different server location, and reconnect
• If you prefer to remain connected within the same geographical area, disconnection and reconnection may link you to another server in the same region.
• Keep performing these tests until you discover the optimal server for your needs.

Global Mode: Enabling this option activates NPV for all online activities, which might hinder the performance of local websites and applications.

Split Mode: This option utilizes NPV solely for sites that are restricted due to geographical barriers, like Google, YouTube, and Netflix, while allowing access to local networks for Chinese websites.

You can modify the routing mode in the App Settings.

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