The split mode feature in Mainland NPV for China enables web applications such as Telegram, WhatsApp, or Gmail, which operate using 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. However, the application versions may utilize different ports.

To ensure access, the following steps should be followed:

• Select 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 log in on a new device and surpass the device limit, you will be redirected to the "Unbind Device" page, allowing you to disconnect any linked devices.
• Alternatively, you can go to "Menu" > "App Settings" > "Device List" to choose and unbind a specific device.

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

• If you can't remember your username, please reach out to us with a screenshot of your payment confirmation.

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

To streamline the process, we now only show regions. Heibao will automatically connect you to the best performing server within your selected region. Here are the details:

• The location menu will exclusively show regions, but each region includes hundreds of servers. When you choose a region, Heibao will automatically connect you to the server that delivers the best performance based on your network conditions.
• If you are 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 satisfies your requirements.

Frequent reasons for network problems include:

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

To address these issues, you may consider 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 detect any connectivity issues. For instance, if your WiFi connection is unstable, switch to a mobile data network.
• 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 another server within the same vicinity.
• Keep performing these tests until you identify the best server for your needs.

Global Mode: Enabling this option turns on NPV for all online activities, which may lead to slower performance on local websites and applications.

Split Mode: This configuration utilizes NPV exclusively for sites that are restricted due to geographic limitations, like Google, YouTube, and Netflix, while allowing local network access for Chinese websites.

You can modify the routing mode in the App Settings.

If you experience difficulties accessing specific websites or applications, consider switching to "Global Mode."
