Internet in China: VPN, SIM Cards and eSIM for Travellers

China operates the world's most sophisticated internet filtering system, blocking access to Google, Facebook, WhatsApp, Instagram, Gmail, YouTube and thousands of other foreign websites and apps. This restriction, commonly called the Great Firewall, affects every foreign visitor the moment their phone connects to a Chinese network.

Staying connected requires one of three solutions: a VPN installed before arrival, a local SIM card or eSIM purchased from a Chinese carrier, or accepting limited access to only Chinese apps and services. Most independent travellers use a combination of all three.

This guide covers exactly which VPNs work as of 2026, where to buy SIM cards at Chinese airports, how to activate an eSIM before your flight, which apps function without a VPN, and what fails when your connection drops. Every solution includes current prices, step-by-step activation instructions, and the most common problems with their fixes.

China blocks all Google services including Search, Maps, Gmail, Drive and Photos. Facebook, Instagram, WhatsApp, Messenger, X (Twitter), Snapchat, Telegram and TikTok international version are inaccessible. News sites like BBC, New York Times, Wall Street Journal and most Western media are blocked. Streaming services including Netflix, Hulu, Spotify and YouTube do not work.

Apps and services that work without VPN

Apple Maps functions normally and shows English place names, metro lines, walking routes and business hours in major cities. iMessage and FaceTime work on iPhone but can be unreliable. Bing search engine works but returns censored results. LinkedIn operates with content restrictions. Chinese apps including WeChat, Alipay, Baidu Maps, Didi (ride-hailing), Meituan (food delivery) and Trip.com work perfectly and are essential for daily activities.

WeChat is the single most important app for China travel. It handles messaging, payments, restaurant menus, metro card top-ups, hotel bookings, train tickets and QR code check-ins at tourist sites. Register WeChat before arriving, as the verification process sometimes requires an existing WeChat user to scan your QR code.

What happens when you lose VPN connection

When VPN disconnects, you immediately lose access to any open Google or Facebook tabs. WhatsApp messages sent while disconnected queue locally and deliver when VPN reconnects. Gmail does not sync. Google Maps freezes on the last loaded view but stops updating your location. This happens frequently on Beijing and Shanghai metro systems, where underground stations have strong local 4G but block VPN traffic.

A VPN (Virtual Private Network) encrypts your internet traffic and routes it through a server outside China, bypassing the Great Firewall. Chinese authorities actively block VPN connections, so only a handful of commercial VPN services work reliably in 2026.

VPNs that work

ExpressVPN costs USD 12.95 per month or USD 99.95 per year and maintains the most stable China connections. Its Lightway protocol reconnects automatically when switching between WiFi and cellular. Astrill costs USD 15 per month or USD 120 per year and works consistently but the Windows app is clunky. Both accept Alipay and WeChat Pay for Chinese users, but foreign travellers should subscribe and pay with a credit card before arrival.

NordVPN and Surfshark work intermittently. They function reliably in Shanghai and Shenzhen but face frequent blocks in Beijing and Chengdu. Both cost around USD 10 per month but require manual server switching when connections fail.

Critical VPN setup steps

Download and install your VPN app before departing for China. All VPN provider websites are blocked inside China, making it impossible to download the software after arrival. Test the connection at home by opening Google and Facebook to confirm it works. Enable auto-connect on your phone so the VPN activates whenever you join a network. Screenshot your VPN account email and password, as you cannot access Gmail to retrieve them in China.

Common VPN failures and fixes

VPN connects but websites time out: Switch to a different server location. Hong Kong and Japan servers are geographically closest but get blocked frequently. Los Angeles and London servers are slower but more stable. VPN disconnects every few minutes: This happens on congested hotel WiFi. Switch to cellular data or try a different VPN protocol in the app settings. ExpressVPN's automatic protocol works best. VPN drains battery quickly: Disable auto-connect and only activate VPN when you need blocked apps, then disconnect. Chinese apps like WeChat and Alipay work faster without VPN active.

A local SIM card from China Mobile, China Unicom or China Telecom gives you a Chinese phone number and cellular data at local prices. Tourist SIM packages include generous data allowances and sometimes limited voice minutes.

Airport SIM card counters

Beijing Capital Airport Terminal 3 has China Mobile and China Unicom desks in the arrivals hall past customs, open 06:00 to 23:00 daily. Shanghai Pudong Terminal 1 and Terminal 2 both have carrier counters in baggage claim areas. Guangzhou Baiyun and Chengdu Shuangliu airports have counters near exit gates. Smaller airports including Xi'an, Guilin and Zhangjiajie often lack carrier counters, so buy SIMs in the city centre at carrier flagship stores.

A 7-day tourist SIM costs CNY 30 to CNY 50 and includes 10GB of 4G data. 15-day packages cost CNY 60 to CNY 80 with 20GB to 30GB. 30-day SIMs cost CNY 100 with 50GB or CNY 150 with 100GB. Voice minutes range from 50 to 200 depending on package. All prices include activation and there are no hidden fees.

SIM card activation process

Bring your passport to the counter. Staff photograph your passport photo page and your face using a tablet. This registration is mandatory under Chinese telecom regulations and takes 2 to 3 minutes. They install the SIM in your phone, enter an activation code, and your number activates within 60 seconds. Save the packaging, which lists your new Chinese phone number, top-up instructions, and the carrier's customer service number.

Your phone must be carrier-unlocked to accept the SIM. Phones purchased directly from Apple, Samsung or Google are usually unlocked. Phones from carriers like Verizon, AT&T, Vodafone or EE are often locked and will not work with a Chinese SIM until you request an unlock code from your home carrier.

City centre SIM card shops

China Mobile flagship stores are common in shopping districts. In Beijing, find stores near Wangfujing shopping street and Sanlitun. Shanghai has stores on Nanjing Road and Huaihai Road. Show your passport and say "tourist SIM card" (the English phrase works fine). Staff speak minimal English but the process is identical to airports. Avoid small independent phone shops, which charge inflated tourist prices of CNY 150 to CNY 200 for the same SIM.

An eSIM is a digital SIM card that installs on compatible phones without a physical card. This lets you keep your home country SIM active for receiving calls and SMS while using a Chinese data plan. eSIMs suit travellers who need to maintain their home number for banking verification codes but want Chinese data.

Compatible devices

iPhone XS, XR and all newer models support eSIM. Google Pixel 3 and newer, Samsung Galaxy S20 and newer, and recent models from Huawei, Xiaomi and Oppo work with eSIM. Check your phone's settings: iPhone users go to Settings > Cellular > Add Cellular Plan, Android users go to Settings > Network > SIM cards. If the option appears, your phone supports eSIM.

eSIM providers for China

Airalo sells China eSIM plans starting at USD 4.50 for 1GB valid 7 days, USD 11.50 for 3GB valid 15 days, and USD 26 for 10GB valid 30 days. Holafly charges USD 19 for 6GB valid 15 days or USD 47 for unlimited data valid 15 days (throttled after 6GB per day). Ubigi costs EUR 9 for 3GB valid 30 days. All plans are data-only with no voice minutes or Chinese phone number.

Purchase and install your eSIM before reaching China. Download the Airalo or Holafly app, select China from the country list, purchase a plan with your credit card, and scan the QR code displayed in the app. The eSIM installs immediately and activates when your phone connects to a Chinese network. This takes 30 seconds after landing.

eSIM limitations

You do not get a Chinese phone number, so you cannot receive SMS verification codes from Chinese services. WeChat registration, Alipay setup and some hotel bookings require a Chinese number. Solve this by registering WeChat and Alipay before your trip using your home number with VPN active, or by buying a physical SIM for CNY 30 just for the number and using eSIM for data.

eSIM data speeds match local SIMs but some eSIM providers route traffic through VPN-like tunnels that get partially blocked. Airalo and Ubigi use standard China Unicom network access without tunneling and work normally. Holafly routes through optimization servers that sometimes trigger Great Firewall blocks, making Google inaccessible even though the eSIM is active. Test this by trying to open Baidu.com (works if network is active) then Google.com (blocked if optimization tunnel is blocked).

Every hotel in China from CNY 150 hostels to CNY 2000 five-star properties offers free WiFi. Connection is usually reliable but speeds vary dramatically. International hotels including Marriott, Hilton and InterContinental properties in Beijing and Shanghai typically provide 50 to 100 Mbps connections suitable for video calls. Budget hotels and hostels often cap speeds at 5 to 10 Mbps, which works for messaging but struggles with photos.

Hotel WiFi registration requirements

Most hotels require your room number and passport number to access WiFi. Some send an SMS verification code to your phone. Connect to the network, open any website, and the login portal appears automatically. Enter your details and click confirm. Access activates for your device for the duration of your stay.

Hotel WiFi faces the same Great Firewall restrictions as cellular data. You need VPN active to reach Google, Facebook and WhatsApp. Chinese apps including WeChat work without VPN. Hotel networks often block VPN traffic more aggressively than cellular networks, causing frequent disconnections. If VPN fails on hotel WiFi, switch to cellular data.

Public WiFi in China

Coffee chains including Starbucks, Luckin Coffee and Pacific Coffee offer free WiFi with WeChat login. Open WiFi settings, select the network, and a WeChat QR code appears. Scan with WeChat to authenticate and you get 2 hours of access. McDonald's and KFC require a Chinese phone number for SMS verification. Shopping malls in Beijing, Shanghai and Shenzhen provide free WiFi but registration requires scanning a QR code with WeChat or Alipay.

Beijing and Shanghai metro systems have free WiFi in stations but not in moving trains. The network name is "Metro WiFi" or similar in Chinese characters. Connection requires app download, making it impractical for tourists. Cellular data works better and China Mobile, China Unicom and China Telecom all maintain 4G coverage on metro trains in Beijing, Shanghai, Guangzhou, Shenzhen and Chengdu.

Internet cafes

Internet cafes exist mainly for gaming and are rare in tourist areas. Access requires Chinese ID card registration, which foreigners cannot complete with just a passport. Avoid internet cafes for general web access.

Install these apps at home before your flight. Downloading apps inside China requires a VPN or switching your phone's app store region to China, both inconvenient.

Communication and navigation

WeChat is mandatory for messaging Chinese hotels, tour guides and new friends. It also handles payments, restaurant menus and tourist site tickets. Register with your home country phone number or email before leaving. VPN makes registration more reliable. Pleco Chinese dictionary is the best offline translator for signs, menus and conversations. Download all language packs before your trip. Apple Maps works without VPN and provides the best English-language navigation in Chinese cities.

Payments and transport

Alipay TourPass lets foreigners link an international credit card for QR code payments without a Chinese bank account. Registration requires your passport photo page scan, so use the in-app camera in good lighting to avoid rejection. Didi is China's Uber equivalent and works in 400 cities. Set it up at home with your home phone number. Trip.com books trains, flights and hotels with English interface and accepts international credit cards.

Offline resources

Maps.me provides detailed offline maps that work without internet or VPN. Download maps for Beijing, Shanghai, Xi'an and other cities you plan to visit. Google Translate offline Chinese language pack works well for simple phrases when VPN is unavailable. Download it through the Google Translate app settings.

VPN apps

Download ExpressVPN or Astrill before departure. Test the connection at home. Screenshot your account credentials in case you need to reinstall. Set VPN to auto-connect on untrusted networks to ensure protection from the moment you land.
