Roaming eSIMs Bypass the Firewall Automatically
Here's how it works: When you use a roaming eSIM from Airalo, Holafly, or Nomad in China, your internet traffic is routed through servers in Hong Kong or Singapore—outside mainland China.
This means you're technically not on the Chinese internet. The Great Firewall doesn't apply to your connection.
✅
Apps That Work
Google, Gmail, YouTube, Instagram, WhatsApp, Facebook, Twitter/X, Telegram, Netflix
❌
Blocked on Local SIM
All the above are blocked if you use a Chinese carrier SIM (China Mobile, China Unicom, etc.)
Do NOT Buy a Local SIM at the Airport
This is the most common mistake tourists make in China.
If you buy a SIM card from China Mobile, China Unicom, or China Telecom at Beijing or Shanghai airport, Google, Instagram, WhatsApp, and Facebook will NOT work. These are blocked on all Chinese carrier networks.
→ Always install your eSIM BEFORE arriving in China.
Why Roaming eSIMs Bypass the Great Firewall
Traffic Routing
Roaming eSIMs connect to Chinese cell towers for signal, but route all your data through servers in Hong Kong, Singapore, or other countries. China's firewall only applies to data that stays within mainland China.
Built-In "VPN"
You don't need to install or configure anything. The eSIM acts as a VPN by default. This is more reliable than traditional VPN apps, which China actively blocks.
No Speed Throttling
Unlike VPNs that can be slow due to server congestion, roaming eSIMs use dedicated international data channels. Expect normal 4G/LTE speeds.

❓ Frequently Asked Questions
Will my eSIM work in all of China?
Yes. Roaming eSIMs use China Unicom or China Mobile towers for connectivity, which cover all major cities and most rural areas. The firewall bypass works everywhere in mainland China.
Is it legal to bypass the Great Firewall?
For foreign tourists, yes. Roaming eSIMs are a legal gray area—they're not technically VPNs, and the government doesn't actively block them. Millions of foreign business travelers and tourists use them without issues.
What if I need to make local Chinese payments (WeChat Pay)?
You can use WeChat with a roaming eSIM, but WeChat Pay requires a Chinese bank account. Most tourists use cash or Alipay Tour Pass instead.
Can I download apps after arriving in China?
Yes, if you have a roaming eSIM. The App Store and Google Play work normally. However, you cannot download Chinese apps like Alipay or DiDi from Western app stores—you'll need to search for APK files or use Chinese alternatives.
