SIM Cards, Internet, and Staying Connected in China

China's internet ecosystem is different from everywhere else. Google, Gmail, WhatsApp, Instagram, Facebook, Twitter, YouTube — all blocked. Not intermittently, not with a slow connection, but completely. This is the reality of the Great Firewall, and it affects every minute of your trip: navigation, communication, payments, restaurant searches, hotel bookings.

The good news is that getting connected is straightforward if you prepare in advance. Here's exactly what to do, in order.

Before You Leave Home

1. Install a VPN. More on this below, but set it up before you arrive — you can't download VPN apps from inside China if the app store is blocked.

2. Download offline maps. Google Maps works poorly in China (it's blocked or shows offset coordinates). Download Baidu Maps (百度地图) or Apple Maps (which works in China) and cache the areas you'll visit.

3. Set up Alipay and WeChat. See our payments guide for the full setup process. Both apps are essential and need to be configured before arrival.

4. Install essential apps: Pleco (Chinese dictionary with OCR camera lookup), Didi (ride-hailing, accessible through Alipay), and a translation app (Baidu Translate or Google Translate with offline language packs downloaded before departure).

SIM Card Options

China Unicom (中国联通) — Best for Foreigners

China Unicom is the most foreigner-friendly carrier. Their SIM cards work with most international phones (they use FDD-LTE bands compatible with global devices), and they offer straightforward tourist packages.

Where to buy: The airport arrivals hall. China Unicom has official counters at Beijing Capital, Shanghai Pudong, Guangzhou Baiyun, and most international airports. Look for the blue 中国联通 signage.

What you need: Your passport. The staff will register the SIM in your name (this is legally required in China) and activate it on the spot.

Tourist packages: Typically ¥100-200 ($14-28) for 15-30 days with 10-30GB of data and some domestic calling minutes. Prices and packages change frequently — ask the counter staff for current options.

Coverage: Good in cities, decent in rural areas. Not the absolute best coverage in remote mountains (that's China Mobile), but perfectly adequate for 95% of travel situations.

China Mobile (中国移动)

The largest carrier with the best rural coverage. However, some older China Mobile plans used TD-LTE bands that aren't compatible with all international phones. Modern phones (iPhone 12+, most 2022+ Androids) work fine. Packages are similar to Unicom.

China Telecom (中国电信)

Generally not recommended for foreigners — their network uses CDMA technology that's incompatible with many international phones.

eSIM Options

If your phone supports eSIM (iPhone XS and later, most recent Samsung/Pixel phones), several providers offer China eSIMs that can be purchased online before your trip:

• Airalo: Offers China eSIMs starting at $4.50 for 1GB (7 days) up to $23 for 10GB (30 days). Easy app-based setup.
• Holafly: Unlimited data plans starting at $19 for 5 days. More expensive but no data anxiety.
• Nomad: Competitive pricing, 10GB for 30 days at around $16.

eSIM advantages: No physical SIM swap needed (keep your home number active), instant activation, no need to find a counter at the airport.

eSIM disadvantages: More expensive per GB than local SIMs, and some eSIM providers route data through servers outside China, which can affect speed.

The VPN Situation

China's Great Firewall blocks most Western internet services. A VPN (Virtual Private Network) is the standard way to bypass this — it encrypts your traffic and routes it through a server outside China.

The reality: China has been cracking down on VPNs for years. Many popular VPNs don't work reliably in China. The situation changes frequently — a VPN that works today might be blocked next month.

What generally works (as of 2026):

• ExpressVPN (consistently reliable in China)
• NordVPN (with obfuscated servers enabled)
• Astrill VPN (popular among China expats)
• VyprVPN (with Chameleon protocol)

What to do:

1. Subscribe and install your VPN before leaving home.
2. Download the VPN's manual configuration guides as a backup (in case the website is blocked).
3. Test the VPN in China immediately and have a backup provider.
4. Enable "stealth" or "obfuscated" mode in your VPN settings — this makes VPN traffic look like regular HTTPS traffic.

Important: Using a VPN in China exists in a legal gray area. Foreign tourists are generally not targeted, but be discreet. Don't post about your VPN use on Chinese social media.

Without a VPN: You can still use Chinese apps (WeChat, Alipay, Baidu Maps, Didi) without any issues. These apps work perfectly inside the Great Firewall. The VPN is only needed for Western services (Gmail, WhatsApp, Instagram, Google, news sites).

Essential Apps for China

WeChat (微信): The everything-app. Messaging, payments, mini-programs for restaurants and services, ride-hailing, and more. You'll use this more than any other app. Set it up before arriving.

Alipay (支付宝): Payments, transit QR codes for metro/bus, Didi ride-hailing, utility payments, and dozens of mini-programs. Your digital wallet in China.

Baidu Maps (百度地图): The Google Maps of China. Accurate, comprehensive, and available in English (though some features are Chinese-only). Download offline maps for your destinations.

Apple Maps: Surprisingly good in China — works without a VPN and has English-language support. A solid backup to Baidu Maps.

Pleco: The best Chinese dictionary app. Its camera OCR feature lets you point your phone at Chinese text (menus, signs, labels) and get instant translations. Essential for navigating restaurants and shops.

Didi (滴滴): China's Uber. Book rides without language barriers — enter your destination in the app, and the driver gets GPS directions. Accessible as a mini-program within Alipay.

Baidu Translate (百度翻译): Better than Google Translate for Chinese-English translation, and works without a VPN. The camera translation feature is useful for menus and signs.

Metro apps: Most Chinese cities have local metro apps, but Alipay's transit QR code feature works on metro systems nationwide — no separate app needed.

Google Services That Don't Work

To be explicit about what's blocked:

• Google Search, Gmail, Google Maps, Google Drive, Google Docs
• WhatsApp, Telegram, Signal
• Facebook, Instagram, Twitter/X, Reddit
• YouTube, Netflix, Spotify
• Dropbox, OneDrive
• Wikipedia (partially blocked)
• Most international news sites (NYT, BBC, Guardian)

Alternatives: Baidu (search), QQ Mail or Outlook (email), Baidu Maps (navigation), WeChat (messaging), Youku/Bilibili (video streaming).

Practical Tips

Airport WiFi: Most Chinese airports offer free WiFi, but it requires a Chinese phone number for SMS verification. If you haven't bought a SIM yet, use the airport's international roaming or VPN before purchasing your SIM.

Hotel WiFi: Most hotels offer free WiFi. Quality varies wildly — luxury hotels are fast and reliable; budget hotels can be slow. Some hotels block certain foreign sites even on their WiFi.

Portable WiFi rental: Available at airport counters (¥30-50/$4-7 per day). A pocket WiFi device that provides a hotspot for multiple devices. Useful for groups or families.

Don't rely on public WiFi: China's public WiFi (in cafes, malls, stations) often requires phone number registration and may be monitored. Use your mobile data instead.

Getting connected in China takes more effort than in most countries, but the payoff is enormous. With Alipay, Baidu Maps, and a working SIM card, you'll navigate China more easily than many locals — and you'll never have to fumble with cash, paper maps, or phrasebooks again.
