What's Blocked in China (February 2026)
China operates the world's most sophisticated internet censorship system, known as the "Great Firewall" (GFW). Unlike Russia's more recent blocks, China has refined these restrictions for over two decades.
- Google (All Services): Search, Gmail, Maps, Drive, YouTube, Play Store – everything
- WhatsApp: Blocked since 2017
- Instagram: Blocked since 2014
- Facebook: Blocked since 2009
- Twitter/X: Blocked since 2009
- Telegram: Blocked
- Signal: Blocked
- Discord: Blocked
- Reddit: Blocked
- Wikipedia (Some languages): Blocked or restricted
- Many news sites: NYT, BBC, Bloomberg, etc.
How PikaSim Bypasses the Great Firewall (Legally)
The Great Firewall uses Deep Packet Inspection (DPI), DNS poisoning, and IP blocking to filter internet traffic. VPNs are constantly detected and blocked. But roaming eSIMs use a completely different architecture that the Firewall cannot easily block.
The International Roaming Loophole
When you use a PikaSim eSIM (issued by a UK carrier) in China, your data follows the standard international roaming protocol:
- Local Connection: Your phone connects to a Chinese tower (China Mobile, China Unicom, China Telecom) for the radio signal only.
- Encrypted Tunnel: The tower identifies your SIM as a foreign roamer. Per GSMA international roaming standards, it must tunnel your data directly to the Home Location Register (HLR) in the UK.
- Exit Point: Your data exits to the public internet in London, not Beijing. Because your IP is British, the Great Firewall never sees or filters your traffic.
Why This Isn't a VPN
VPNs encrypt your data after it's already on the Chinese internet – the GFW can still detect VPN protocols and block them. A roaming eSIM routes traffic at the network level before it ever touches Chinese internet infrastructure. It's hardware-level routing, not app-level encryption.
Technical Comparison
| Step | Local Chinese SIM | PikaSim (UK Routing) |
|---|---|---|
| 1. Phone connects to tower | China Mobile (local) | China Mobile (roaming) |
| 2. Data routing | Through Chinese ISP | Tunneled to UK via GRX |
| 3. Great Firewall | Filters all traffic | Bypassed entirely |
| 4. Internet exit point | Beijing (filtered) | London (unfiltered) |
| 5. Google/WhatsApp | Blocked | Works normally |
Why China Can't Block International Roaming
The Great Firewall is extremely sophisticated at blocking VPNs. So why can't it block roaming eSIMs? Three key reasons:
1. International Treaties
China is a signatory to ITU (International Telecommunication Union) treaties that guarantee "freedom of transit" for international telecommunications. Blocking roaming would violate these agreements and potentially trigger retaliatory measures from other countries.
2. Economic Necessity
China receives millions of business travelers, tourists, and diplomats annually. All of them expect their foreign SIMs to work. Blocking international roaming would devastate tourism and business relationships – an unacceptable trade-off even for the CCP.
3. Technical Architecture
Roaming traffic is encrypted end-to-end between the local tower and the home carrier's gateway. The Great Firewall can see that roaming traffic exists, but cannot inspect or filter it without breaking the entire roaming system.
Is using a foreign eSIM legal in China?
Yes. Using a foreign SIM for roaming is a standard, protected telecommunications service. China's VPN bans specifically target VPN software and domestic VPN providers – not international roaming, which is protected by global telecom agreements.
Feature Comparison: Options in China
| Feature | Local Chinese SIM | VPN App | PikaSim eSIM |
|---|---|---|---|
| Google Access | Blocked | Unreliable | Works |
| Blocked | Unreliable | Works | |
| Blocked | Unreliable | Works | |
| Setup Difficulty | ID Registration | Complex (blocked often) | One-click install |
| Works on Arrival | After registration | Maybe (download before) | Instant |
| Blocking Risk | N/A (always filtered) | High (blocked daily) | Very Low |
| Battery Impact | Normal | High (encryption) | Normal |

Step-by-Step Setup Guide
Get Started in 2 Minutes
- Get a PikaSim eSIM:
- Visit PikaSim's China eSIM page or download the PikaSim app
- Choose a data plan (1GB, 3GB, 5GB, etc.)
- Pay with card or crypto – no account required
- Install before you fly:
- iPhone & Android: Tap the install link – that's it
- Or scan the QR code if you prefer
- The eSIM installs automatically in seconds
- Pro tip: Install before leaving – the Play Store is blocked in China
- Turn it on when you land:
- Enable the PikaSim data line in your phone settings
- Open Google Maps – it works immediately
- All blocked apps now function normally
Important: Install Before Arriving
The Google Play Store is blocked in China. If you have an Android phone, install the PikaSim app or download your eSIM before you travel. iPhone users can install anytime via the App Store (which works in China).
FAQ
Will this work for Google Maps navigation?
Yes! Google Maps works perfectly with a roaming eSIM. Note that Google Maps data for China is slightly offset for security reasons (a Chinese government requirement), but the app functions normally.
Can I use Gmail for work?
Absolutely. Gmail, Google Drive, Google Docs – the entire Google Workspace suite works normally through the UK routing.
Is this faster than a VPN?
Usually yes. VPNs add encryption overhead and often use congested servers. Roaming routes through carrier-grade infrastructure that's optimized for international traffic.
What if the VPN I downloaded stops working?
This is common – China actively blocks VPN protocols. With PikaSim, there's nothing to block because you're using standard roaming protocols that can't be filtered without breaking international telecom agreements.
Can authorities see I'm using a foreign eSIM?
They can see a foreign roamer connected to the tower, which is completely normal for any visitor. They cannot inspect your traffic because it's tunneled directly to the UK before hitting the internet.
Does this work for video calls?
Yes. WhatsApp calls, FaceTime, Google Meet, Zoom – all video calling works normally.
How much data do I need?
For messaging and maps: 1-2GB per week. For video calls and some streaming: 5-10GB per week. Heavy streaming users should consider 10GB+ plans.
Will Chinese apps still work?
Yes. WeChat, Alipay, Didi, and other Chinese apps work fine. Your traffic to Chinese services routes through the UK and back, adding minimal latency.
