As of 2026, linking your VPN in China does NOT automatically guarantee full functionality. Users frequently encounter issues such as:
- Connection established, but international websites won’t load;
- Google is accessible, yet YouTube/ChatGPT are not;
- Extremely slow internet speeds;
- Apps function properly, but sites are unresponsive;
- WiFi is operational, while mobile data fails—or the other way around.
This manual presents the most effective testing techniques to confirm if your VPN is indeed operational in China.
1. Step One: Verify Basic Connectivity
See if you can access:
- https://www.google.com
- https://www.youtube.com
- https://chat.openai.com
If these websites don't load:
- Your DNS might be compromised;
- The server could be partially restricted;
- The protocol may have been identified.
2. Step Two: Assess DNS Integrity
DNS issues are among the primary reasons for disruptions in China.

Concerning signals:
- DNS servers operated by China Telecom, Unicom, or Mobile;
- Discrepancy between IP and server location.
Solution:
- Activate built-in DNS (DoH/DoT);
- Opt for SmartDNS mode.
3. Step Three: Confirm Your IP Geography

Verify:
- Your IP displays Japan/Singapore/etc. if you have selected those;
- No alerts for “Suspicious Proxy”.
4. Step Four: Conduct a Speed Test

- https://speed.cloudflare.com
Typical performance indicators:
- General web browsing: 1–5 Mbps;

- 4K streaming: 15 Mbps or more;
5. Step Five: Test Streaming Services
- Netflix region verification;
- Login for Disney+;
- YouTube 4K streaming test.
If streaming doesn't work:
- Shift to nodes that support streaming;
- Employ SmartDNS.
6. Step Six: AI Tool Compatibility Check
- ChatGPT message functionality;
- OpenAI interface;
- Midjourney access on Discord.
7. Final Step: Application Usability
