Ways to Check If Your VPN is Functioning Properly in China (2026)

As of 2026, simply connecting your VPN in China doesn’t guarantee its proper functionality. Numerous users encounter issues such as:

• Connection established, but international websites are inaccessible;
• Google is accessible, yet YouTube/ChatGPT is not;
• Browsing is remarkably sluggish;
• Applications function, but websites do not;
• WiFi is operational while mobile data is not—or the other way around.

This manual outlines the most effective testing techniques to determine if your VPN is genuinely operational in China.

1. Initial Step: Verify Basic Connectivity

Test your ability to access:

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

If these URLs cannot be accessed:

• Your DNS might be compromised;
• The server could be partially restricted;
• The connection type may have been identified.

2. Second Step: Assess DNS Functionality

DNS issues are among the most frequent reasons for connectivity problems in China.

Warning signs:

• DNS servers associated with China Telecom, Unicom, Mobile;
• IP address location does not align with server location.

Resolution:

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

3. Third Step: Verify Your IP Address Location

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

Confirm:

• Your IP reflects Japan/Singapore/etc., if chosen;
• No warnings about “Suspicious Proxy”.

4. Fourth Step: Conduct a Speed Test

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

Typical speed ranges:

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

5. Fifth Step: Evaluate Streaming Capability

• Netflix regional check;
• Disney+ login attempt;
• YouTube 4K evaluation.

If streaming fails:

• Switch to nodes that support streaming;
• Employ SmartDNS.

6. Sixth Step: Verify AI Tool Compatibility

• Test ChatGPT functionality;
• Check OpenAI dashboard;
• Midjourney on Discord.

7. Last Step: Assess App Performance

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