The split mode functionality in Lingti NPV for China accommodates web applications such as Telegram, WhatsApp, or Gmail that operate over 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 application versions may utilize different ports.

To guarantee access, the following steps should be taken:

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

• If you try to log in on a new device and reach the device limit, you will be directed to the "Unbind Device" page, allowing you to disconnect 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 common issue, 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 attach a screenshot of your payment confirmation.

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

To make this easier, we now only showcase 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 showcase only regions, but within each region, there are hundreds of servers. When you choose a region, Heibao automatically connects you to the server that provides optimal performance based on your network conditions.
• If you're unhappy with the server to which you are connected, you can disconnect and reconnect to the same region to be assigned a different server.
• You can repeat this process until you identify a server that suits your requirements.

Typical factors contributing to network problems include:

• Slow local internet speeds (without utilizing a NPV)
• Elevated user traffic at specific NPV server sites

To address these problems, you might consider the following solutions:

• Assess 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 connection issues. For instance, if your WiFi is inconsistent, try using a mobile data connection.
• Disable the NPV, select a new 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 a different server in the same region.
• Keep performing these tests until you identify the most suitable server for your needs.

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

Split Mode: This mode applies NPV solely for websites that are restricted due to geographic limitations, such as Google, YouTube, and Netflix, while allowing local network access for Chinese sites.

You can modify the routing mode in the App Settings.

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