The split mode feature in JetStream NPV for China accommodates web applications such as Telegram, WhatsApp, or Gmail that use HTTPS. This mode can modify the routing for both HTTP (port 80) and HTTPS (port 443), enabling access to the web versions of these applications. However, the versions of the applications may be utilizing different ports.

To ensure accessibility, the following steps should be taken:

• Enable the "Global Mode" option found in the routing settings.
• Adjust the proxy settings of the application. For instance, here’s how you can alter the proxy settings for the LINE app:
  
  

• Should you try to log in on a new device and exceed the device limit, you will be redirected to the "Unbind Device" page, where you can disconnect any linked devices.
• Additionally, you can go to "Menu" > "App Settings" > "Device List" to choose and unbind a device you prefer.

It's normal to forget usernames or passwords, 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 include a screenshot of your payment receipt.
• If you’ve forgotten your password, simply use the "forgot password" option in the app.

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

To make things easier, we now display only regions. Heibao will automatically connect you to the best-performing server within your selected region. Here are the details:

• The location menu will show only regions, but each region includes hundreds of servers. When you pick a region, Heibao automatically connects you to the server that delivers the best performance based on your network conditions.
• If you're not happy with the server you're connected to, you can disconnect and reconnect to the same region for a different server.
• You can continue this process until you locate a server that suits your needs.

Common reasons for network problems include:

• Local slow internet speeds (without using a NPV)
• Increased user activity at specific NPV server sites

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

• Verify your local internet speed by momentarily turning off the NPV
• Experiment with various network connections like WiFi, 4G, or 5G while the NPV is disabled to pinpoint 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 connected to the same geographical area, disconnect and reconnect, as this might connect you to a different server in the same region.
• Keep performing these checks until you identify the most appropriate server for your needs.

Global Mode: Enabling this option activates NPV for all online activities, which may cause local websites and apps to load more slowly.

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

You can modify the routing mode in the App Settings.

If you experience difficulties accessing certain websites or apps, consider switching to "Global Mode."
