As of 2026, simply establishing your VPN in China doesn’t guarantee its full functionality. Users often face issues such as:
- Successful connection, yet foreign websites are inaccessible;
- Google is operational, but YouTube/ChatGPT encounters issues;
- Browsing speed is exceedingly slow;
- Apps function, but not the websites;
- WiFi is working, but mobile data is not—or the other way around.
This guide outlines the most effective testing methods to confirm whether your VPN is indeed operational in China.
1. First Step: Verify Basic Connectivity
Determine if you can access:
- https://www.google.com
- https://www.youtube.com
- https://chat.openai.com
If these websites do not load:
- Your DNS may be compromised;
- The server might be partly restricted;
- The protocol could be recognized.
2. Second Step: Assess DNS Integrity
DNS issues are a prevalent reason for connectivity problems in China.

- Discrepancy between IP address location and server location.
Solution:
- Activate built-in DNS (DoH/DoT);
- Utilize SmartDNS mode.
3. Third Step: Verify Your IP Location

Confirm:
- Your IP reflects Japan/Singapore/etc. if that option was chosen;
- No “Suspicious Proxy” alerts.
4. Fourth Step: Perform a Speed Test
- https://fast.com
- https://speed.cloudflare.com
General speed indicators:
- Basic surfing: 1–5 Mbps;
- YouTube at 1080p: 5–12 Mbps;
- 4K streaming: 15+ Mbps;
5. Fifth Step: Test Streaming Functionality
- Regional Netflix assessment;
- Logging into Disney+;
- YouTube 4K evaluation.
If streaming doesn’t work:
- Switch to nodes that support streaming;
- Employ SmartDNS.
6. Sixth Step: Compatibility with AI Tools
- Test message functionality on ChatGPT;
- OpenAI control panel;
- Use Midjourney on Discord.
7. Final Step: Evaluate App Performance
