Steps to Verify Whether Your VPN Is Functioning Properly in China (2026)

As of 2026, simply having your VPN connected in China does not guarantee it is operating correctly. Many individuals face challenges such as:

• Connection established, yet international websites fail to load;
• Google is accessible, but YouTube/ChatGPT are not;
• Browsing is incredibly sluggish;
• Applications function, while web pages do not;
• WiFi operates, but mobile internet does not—or the other way around.

This guide presents practical approaches to test and confirm the functionality of your VPN in China.

1. First Step: Verify Basic Connectivity

Try to access:

• https://www.google.com
• https://www.youtube.com
• https://chat.openai.com

If these websites do not load:

• Your DNS settings might be compromised;
• Some servers could be partially restricted;
• The protocol may be flagged.

2. Second Step: Validate DNS Integrity

DNS corruption is a prevalent issue in China that can lead to connectivity failures.

Warning signs:

• DNS servers belonging to China Telecom, Unicom, or Mobile;
• Discrepancy between the IP's geographical position and its actual server location.

Solutions:

• Activate built-in DNS (DoH/DoT);
• Switch to SmartDNS mode.

3. Third Step: Assess Your IP Location

• https://ifconfig.co
• https://ipinfo.io

Verify:

• Your IP indicates Japan/Singapore/etc. based on your selection;
• No “Suspicious Proxy” alerts are present.

4. Fourth Step: Conduct a Speed Test

• https://fast.com
• https://speed.cloudflare.com

Typical performance metrics:

• Basic browsing: 1–5 Mbps;
• YouTube 1080p: 5–12 Mbps;
• 4K streaming: 15+ Mbps;

5. Fifth Step: Streaming Capability Test

• Regional Netflix test;
• Login to Disney+;
• YouTube 4K test.

If streaming is unsuccessful:

• Connect to nodes that support streaming;
• Utilize SmartDNS.

6. Sixth Step: Compatibility with AI Tools

• Test messages on ChatGPT;
• Access the OpenAI dashboard;
• Use Midjourney on Discord.

7. Final Step: Application Performance

• Instagram / Facebook;
• WhatsApp;
• Google Maps;
• YouTube;
• Zoom.
