The split mode functionality in Ins NPV for China accommodates web applications such as Telegram, WhatsApp, and Gmail that leverage HTTPS. This mode can modify the routing for both HTTP (port 80) and HTTPS (port 443), making it easier to access the web versions of these applications. Nevertheless, the application versions might operate on various other ports.

To guarantee access, the following steps should be taken:

• Utilize the "Global Mode" option found in the routing settings.
• Adjust the application’s proxy settings. For instance, here’s how to change 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.
• Additionally, you can go to "Menu" > "App Settings" > "Device List" to choose and unbind a device as 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, kindly reach out to us and send a screenshot of your payment record.
• If you have misplaced your password, simply utilize the "forgot password" feature in the app.

We've observed that some users have difficulty selecting a server after choosing a region.

To make things easier, 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 only show regions, but each region has hundreds of servers. When you choose a region, Heibao automatically links you to the server that provides the best 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 connected to a different server.
• You can repeat this process until you discover a server that fits your needs.

Frequent reasons for network problems consist of:

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

To address these challenges, you can attempt the following approaches:

• Assess your local internet speed by temporarily deactivating the NPV
• Experiment with various network connections such as WiFi, 4G, or 5G with the NPV disabled to diagnose any connectivity issues. For instance, if your WiFi is inconsistent, switch to a mobile data connection.
• 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 a different server within that region.
• Keep conducting these tests until you discover the best server for your needs.

Global Mode: Enabling this option activates NPV for all online activities, which could cause local websites and applications to run slower.

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

You can alter the routing mode in the App Settings.

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