Staying connected in China requires a bit of advance preparation — the Great Firewall blocks Google, WhatsApp, Instagram, and most Western apps. But with the right SIM card and app strategy, staying in touch is easy and affordable.

The Great Firewall: What’s Blocked
China operates an extensive internet filtering system (officially the “Golden Shield Project”, colloquially the Great Firewall) that blocks access to most Western internet services:
Blocked in China (without VPN)
- Google (Search, Maps, Gmail, YouTube, Drive, Translate)
- Facebook, Instagram, WhatsApp, Messenger
- Twitter/X, Snapchat, TikTok (the international version — Douyin works)
- Wikipedia (most language versions)
- New York Times, BBC News, Bloomberg (many Western news sites)
- Dropbox, Slack, Discord
- Zoom (sometimes; unreliable)
Works Fine in China (No VPN Needed)
- WeChat, Alipay
- Baidu Maps, Amap (高德地图) — the best navigation apps in China
- DiDi (滴滴) — ridesharing
- Meituan (美团) — food delivery, restaurant reviews
- Didi Translate / Microsoft Translate (offline packs downloaded outside China)
- Apple services (iCloud, App Store, FaceTime) ✅
- Telegram ✅ (works without VPN as of 2025)
- LinkedIn ✅ (mostly works)
- Netflix downloads (pre-downloaded, not streaming)
- Spotify downloads (pre-downloaded)
SIM Card Options
Option 1: Buy a Tourist SIM on Arrival (Recommended)
Available at: Major international airports (Beijing Capital, Pudong, Guangzhou Baiyun) in the arrivals hall.
Three major carriers offer tourist SIMs:
| Carrier | Card Name | Data | Duration | Price |
|---|---|---|---|---|
| China Unicom | 沃派卡 | 30–100GB | 30 days | ¥79–¥199 |
| China Mobile | 流量卡 | 50–100GB | 30 days | ¥99–¥149 |
| China Telecom | 畅游卡 | 30GB | 30 days | ¥99 |
What you get: Chinese phone number + data SIM + some calling minutes. Most cards don’t include international roaming or access to blocked websites.
Registration: SIM registration requires your passport. Airport stalls handle this on the spot.
Option 2: eSIM Before Departure (Best for Tech-Savvy Travellers)
eSIM services designed for China travellers offer clean data without VPN blocks because they route through Hong Kong or international networks:
Recommended eSIM providers:
- Airalo (China Unicom plans) — ¥80–¥150 for 5–30GB
- Gigsky — good for multi-country trips
- CMHK (China Mobile Hong Kong) — data works across mainland China via roaming
The big advantage: Some CMHK Hong Kong SIMs allow access to Google, WhatsApp, etc. because traffic routes internationally — effectively a built-in “VPN bypass.”
Option 3: International Roaming from Home
Expensive (typically USD $15–$30/day) but zero setup required. Suitable for very short trips (2–3 days).
Note: Your international data is subject to the same Great Firewall restrictions — it’s not a workaround.
Option 4: Pocket WiFi (Portable Router)
Rental available at major airports. Provides a WiFi hotspot for multiple devices.
- Price: ¥50–¥80/day
- Data: Usually unlimited or 1–3GB/day high-speed then throttled
- Return: Drop at airport on departure
Getting Around the Great Firewall: VPN Options
Important: VPN use is technically illegal in China for non-enterprise users, though enforcement against tourists is essentially non-existent. The Chinese government focuses enforcement on businesses and citizens, not foreign tourists.
VPNs That Work in China (as of 2025)
Set these up BEFORE you enter China — downloading VPN apps is blocked once you’re inside the firewall.
| VPN | Reliability | Speed | Price |
|---|---|---|---|
| ExpressVPN | ⭐⭐⭐⭐⭐ Best for China | Fast | $8–$13/month |
| AstroVPN / Astrill | ⭐⭐⭐⭐ | Very fast | $12/month |
| NordVPN | ⭐⭐⭐ | Good | $4–$6/month |
| Surfshark | ⭐⭐⭐ | Good | $2–$4/month |
Setup checklist:
- Subscribe and install on all devices before leaving home
- Download the China-specific server list within the app
- Test it before you go (connect and check it works)
- If it stops working inside China, try switching protocols to “Lightway” (ExpressVPN) or “Stealth” mode
Essential Apps to Install Before Departure
Navigation
- Amap (高德地图) ✅ — Best mapping for China; real-time traffic, public transport, walking. Download offline maps for your destinations.
- Baidu Maps (百度地图) — Alternative; Chinese only but excellent coverage
Communication (China-Friendly)
- WeChat (微信) — The single most important app in China. Everyone uses it for messaging, payments, restaurant menus, transport. Create your account before you go.
- Alipay (支付宝) — Digital payment; also has in-app maps and services
Translation
- Microsoft Translator — Download offline Chinese language pack before entering China
- Pleco — Best Chinese dictionary app; works offline
- Google Translate — Blocked without VPN; download offline pack as backup
Transport
- DiDi (滴滴) — Uber equivalent; international version available for foreigners, accepts foreign cards
- Trip.com — Trains, flights, hotels; English UI
- 12306 (China Rail) — Official train booking app (Chinese only; use Trip.com instead)
Food & Lifestyle
- Meituan (美团) — Restaurant finder, food delivery
- Dianping (大众点评) — Yelp-equivalent for restaurant reviews

Making Calls Back Home
WhatsApp / FaceTime
- WhatsApp: Blocked without VPN
- FaceTime (Apple): Works without VPN ✅
- iMessage: Works without VPN ✅
WeChat Video/Voice Calls
Works perfectly in China. If you can get your family/friends to install WeChat before your trip, it’s the most reliable free communication option.
Calling China from Abroad (for Emergencies)
China country code: +86 Drop the leading 0 from the area code when calling from outside China.
International SIM Calls
If you need to make international calls, check your carrier’s international rates. Most tourist SIMs in China only include domestic calls.
Dealing With Common Problems
”I can’t access the internet at all”
- Check your SIM is registered and activated (call 10086 for China Mobile, 10010 for Unicom)
- Try turning airplane mode on and off
- If on WiFi — hotel WiFi sometimes has blocks even on top of the Great Firewall
”My VPN stopped working”
VPN providers regularly update their server lists to stay ahead of blocks. Within the app:
- Try different servers (Hong Kong, Japan, Singapore often work best)
- Switch protocol to Stealth/Obfuscated mode
- Try using mobile data instead of hotel WiFi (different network, different blocks)
“WeChat account got suspended”
WeChat occasionally requires a verification call from an existing WeChat user. Have a WeChat-using contact ready to verify you when you set up the account.
