The split mode feature in O2 NPV for China is compatible with web applications such as Telegram, WhatsApp, or Gmail, which make use of 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 application versions might utilize different ports.

To ensure 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 change the proxy settings for the LINE app:
  
  

• When you try to log in on a new device and go beyond 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 device that you prefer.

Forgetting usernames or passwords is a frequent occurrence, and we strive to simplify the recovery process. Here are your options:

• If you can't recall your username, please reach out to us and include a screenshot of your payment history.
• If you've misplaced your password, simply utilize the "forgot password" option found in the app.

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

To make this easier, we now only showcase regions. Heibao will automatically connect you to the top-performing server in your chosen region. Here are the details:

• The location menu will solely show regions, but every region includes hundreds of servers. Once you choose a region, Heibao automatically connects 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 connect to a different server.
• You can continue this process until you discover a server that fits your needs.

Common reasons for network problems include:

• Slow local internet speeds (without employing a NPV)
• Increased user traffic in specific NPV server locations

To fix these problems, you can attempt the following solutions:

• Verify your local internet speed by temporarily 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 is inconsistent, try using a mobile data connection.
• Disable the NPV, switch to a different server location, and then reconnect
• If you prefer to remain in the same geographical area, disconnect and then reconnect, as this may connect you to another server within the same region.
• Keep conducting these tests until you discover the most appropriate server for your needs.

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

Split Mode: This configuration applies NPV only to sites that are restricted based on geographic location, such as Google, YouTube, and Netflix, while preserving local network access for Chinese websites.

You can modify the routing mode in the App Settings.

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

While there are free O2 NPV for China and proxy services accessible, using free O2 NPV for China is typically discouraged as they often lack the privacy and security features of paid O2 NPV for China.
