As of 2026, simply having your VPN connected in China does not guarantee its full functionality. Users often encounter issues such as:
- Connected, yet unable to access foreign websites;
- Google functions, but YouTube/ChatGPT do not;
- Browsing speeds are extremely slow;
- Apps are operational, while websites are not;
- WiFi is accessible, but mobile data isn't—or the other way around.
This guide outlines effective methods for testing the functionality of your VPN in China.
1. Step One: Verify Basic Connectivity
Determine if you can access:
- https://www.google.com
- https://www.youtube.com
- https://chat.openai.com
If these sites are unreachable:
- Your DNS might be restricted;
- The server may be partly blocked;
- The protocol could be visible.
2. Step Two: Validate DNS Integrity
DNS restrictions are a prevalent issue in China.

Warning signs:
- DNS servers linked to China Telecom, Unicom, or Mobile;
- Discrepancies between your IP's location and the server's location.
Solution:
- Activate built-in DNS (DoH/DoT);
- Utilize SmartDNS mode.
3. Step Three: Assess Your IP Location

Check to ensure:
- Your IP indicates Japan/Singapore/etc. if that's what you chose;
- No alerts for “Suspicious Proxy.”
4. Step Four: Conduct a Speed Test

Typical benchmarks:
- Basic browsing: 1–5 Mbps;

- 4K streaming: 15+ Mbps;
5. Step Five: Streaming Capabilities Test
- Netflix regional access;
- Disney+ login check;
- YouTube 4K streaming test.
If streaming encounters issues:
- Change to nodes that support streaming;
- Implement SmartDNS.
6. Step Six: Compatibility with AI Tools
- Testing ChatGPT messaging;
- Accessing OpenAI dashboard;
- Using Midjourney on Discord.
7. Last Step: Functionality of Apps
- Instagram / Facebook;
