As of 2026, simply connecting your VPN in China does not guarantee it is functioning correctly. Many users encounter problems such as:
- Connected, yet foreign websites fail to load;
- Google is accessible, but YouTube/ChatGPT won’t function;
- Slow internet speeds;
- Applications run, but websites are inaccessible;
- WiFi is operational, but mobile data isn’t, or the other way around.
This guide outlines the most effective methods to test if your VPN truly operates in China.
1. Step One: Verify Basic Connectivity
Test the following URLs:
- https://www.google.com
- https://www.youtube.com
- https://chat.openai.com
If these websites do not load:
- Your DNS settings may be compromised;
- The server access may be limited;
- The protocol might be detected by filters.
2. Step Two: Assess DNS Integrity
DNS issues are among the top reasons for connectivity failures in China.

Warning signs:
- DNS servers belong to China Telecom, Unicom, or Mobile;
- Discrepancy between your IP's location and the designated server's location.
Solutions:
- Activate built-in DNS (DoH/DoT);
- Utilize SmartDNS functionality.
3. Step Three: Verify Your IP’s Geolocation

Check that:
- Your IP reflects Japan/Singapore/etc., as selected;
- No “Suspicious Proxy” alerts are present.
4. Step Four: Conduct a Speed Test
- https://fast.com
- https://speed.cloudflare.com
Typical speed metrics:
- Basic browsing: 1–5 Mbps;
- YouTube 1080p: 5–12 Mbps;
- 4K streaming: 15+ Mbps;
5. Step Five: Perform a Streaming Test
- Test Netflix for your region;
- Login to Disney+;
- Run a YouTube 4K test.
If streaming does not succeed:
- Switch to nodes that support streaming;
- Implement SmartDNS.
6. Step Six: Verify AI Tool Compatibility
- Test ChatGPT messaging;
- Access OpenAI dashboard;
- Use Midjourney via Discord.
7. Final Step: Check App Performance
- Instagram / Facebook;
- WhatsApp;
- Google Maps;
- YouTube;
- Zoom.
