The split mode feature in iOS NPV for China is compatible with web applications such as Telegram, WhatsApp, or Gmail that use 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 might utilize several other ports.

To guarantee access, the following steps should be taken:

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

• If you try to log in on a new device and go over the device limit, you will be redirected to the "Unbind Device" page where you can disconnect any linked devices.

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

To make things easier, we now only show 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 pick a region, Heibao will automatically connect 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 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 consist of:

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

To address these problems, consider trying 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 is inconsistent, switch to a mobile data connection.
• Disable the NPV, select a new server location, and reconnect
• If you prefer to remain connected to the same geographical area, disconnect and reconnect, as this might connect you to a different server within the same region.
• Keep conducting these tests until you identify the most appropriate server for your needs.

Global Mode: Activating this option enables NPV for all online activities, which may result in slower performance for local websites and applications.

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

You can modify the routing mode in the App Settings.

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