Surviving China: Payments, Apps, SIM Cards, and Cultural Survival

Introduction: Why the First 48 Hours in China Are the Hardest

You step off the plane in Beijing or Shanghai, clear immigration, walk to the taxi rank, and then you realize: you can't pay for the taxi. Your credit card doesn't work at the taxi terminal. You don't have Chinese cash. Alipay wants a Chinese phone number that you don't have yet.

This scenario is entirely avoidable. China's payment and digital ecosystem is so thoroughly different from the rest of the world that unless you set it up before you arrive, you will hit a wall.

Part One: The Payment System — Why Cash and Credit Cards Are Practically Useless

China Is a Post-Cash Society

In major Chinese cities (Beijing, Shanghai, Shenzhen, Hangzhou), an estimated 85-90% of transactions happen via mobile payment apps. Many small vendors — street food stalls, fruit stands, temple donation boxes — have QR code signs and don't carry change. Credit cards (Visa, Mastercard, Amex) are accepted at international-brand hotels, upscale malls, and some tourist attractions. That's approximately 15% of where you'll actually spend money.

Bottom line: You need mobile payments BEFORE you go to China.

Alipay (支付宝, Zhifubao) — The #1 App You Need

Alipay is China's most widely used payment app with approximately 1.3 billion active users. It pays for things by QR code, transfers money, orders food delivery, hails rides, and pays utility bills.

Setting it up before you fly:

1. Download Alipay from your home app store (iOS App Store or Google Play) — do NOT wait until you're in China
2. Register with your international phone number (+1, +44, +61, etc.)
3. Verify your identity with your passport — this takes 24-48 hours for approval
4. Link an international credit/debit card (Visa, Mastercard, Amex) — go to "Me" → "Bank Cards" → "Add Card"
5. Test it before departure — send a small amount to verify the setup works

Using it in China:

• At a restaurant/store: Open Alipay → tap "Scan" (扫一扫) → scan the merchant's QR code → enter the RMB amount → confirm
• If the merchant needs to scan YOUR code: Open Alipay → tap "Receive Money" (收钱) → show the QR code on your screen

Common problems:

• "Card declined": Usually your home bank blocking the transaction. Call them before you travel and notify them of your China trip.
• "Transaction limit exceeded": Complete passport verification before departure.
• "Merchant doesn't accept foreign cards": Use cash (ATM) or try WeChat Pay as a backup.

WeChat Pay (微信支付) — The #2 App (But Still Essential)

WeChat is China's everything-app: messaging, social media, payments, ride-hailing, and food delivery. WeChat Pay is the payment function embedded in WeChat.

Setting it up: Same as Alipay — download WeChat, register with international phone number, verify with passport, link card. WeChat Pay is accepted at most of the same places as Alipay. Together, they cover approximately 95% of payment scenarios in urban China.

Cash and ATMs: When You Still Need RMB

There are still situations where you need cash:

• Small vendors in rural areas
• Temples and some tourist sites that only accept cash donations
• ATMs at international airports dispense RMB immediately upon arrival
• Use a global ATM card (Charles Schwab, Wise, Revolut) to minimize fees

Part Two: SIM Cards and Getting Connected

The Great Firewall: What You Need to Know

China's internet is filtered. Google, Gmail, Google Maps, YouTube, Facebook, Instagram, WhatsApp, and most Western social media are blocked. This sounds like a disaster. It isn't — China has its own digital ecosystem that does everything. You just need data to access any of it.

Option 1: Buy a Chinese SIM Card at the Airport (Easiest)

The three major carriers at Chinese airports:

• China Mobile (中国移动): Largest network, best rural coverage
• China Telecom (中国电信): Fast urban data
• China Unicom (中国联通): Better international roaming agreements

At the kiosk: Bring your passport (required by law for SIM registration), buy a prepaid SIM (¥80-120 for 30 days, 10-20GB data + calling minutes), staff registers the SIM to your passport and makes sure it works before you leave.

Pros: Works immediately upon landing, no prior planning, staff helps with setup Cons: Slightly more expensive than city options; staff English varies

Option 2: Buy an eSIM Before You Fly

Airalo and Nomad offer China data plans: approximately $10-15 for 1-3GB (7 days), $25-35 for 5-10GB (30 days).

Requirements: iPhone 14+ or recent Samsung/Pixel with eSIM support

Pros: Data works immediately on landing; no airport kiosk needed Cons: Only works on newer phones; plan required before departure

Option 3: International Roaming From Your Home Carrier

Most Western carriers offer travel passes ($10-15 per day). International roaming may route your traffic through your home gateway — meaning Google/WhatsApp might work, but Chinese apps (Alipay, WeChat, Didi) may be slow or not function properly. Use this only as a temporary bridge.

Option 4: Portable WiFi ("Pocket WiFi") Rental

Rent a portable WiFi device before you fly (via Klook, Trip.com, or at the airport). Creates a WiFi hotspot for up to 5 devices.

Pros: Multiple people share one device Cons: Extra device to carry and charge; 6-8 hour battery life; steep penalty if lost (¥1,000-2,000)

The VPN Question: How to Access Western Internet in China

China's "Great Firewall" blocks Google, Gmail, WhatsApp, Facebook, Instagram, YouTube, and Twitter/X.

• Get a VPN BEFORE you arrive. Once you're in China, VPN websites are blocked and app stores may not show VPN apps. Most reliable in China: ExpressVPN, NordVPN, Astrill — but no VPN works 100% of the time
• WeChat works internationally — download it and message friends/family through it
• WeChat also has a "WeChat Out" feature for calling international phone numbers
• Most high-end hotels have "international internet gateways" for guests

Part Three: Essential Apps for China

1. Alipay (支付宝) — Already covered above (see Part One)

2. WeChat (微信) — Messaging + Payments + Everything

WeChat is not just a messaging app — it's an entire ecosystem:

• Messaging: Works internationally (unlike WhatsApp in China)
• WeChat Pay: Mobile payment (see Part One)
• Mini Programs: In-app services (taxi, food delivery, train tickets)
• WeChat Out: International calling feature
• Scan: QR code scanner for payments and adding friends

3. DiDi (滴滴出行) — China's Uber

Didi is China's ride-hailing app. Enter destination, match with driver, pay via Alipay/WeChat/cash. Didi has an English interface. Set your language to English before you need it. The driver sees the destination on their map and you can message them through the app.

4. Trip.com (formerly Ctrip) — Hotels + Flights + High-Speed Rail

The English-language version of China's largest travel platform. It's the only platform where you can book Chinese high-speed rail tickets in English with an international credit card. Download before you fly — you'll need it immediately upon arrival.

5. Pleco — The Chinese Dictionary That Does Everything

The gold standard Chinese-English dictionary app:

• OCR (camera translation): Point your camera at Chinese text — menus, street signs, anything
• Audio pronunciation: Hear words spoken aloud
• Handwriting recognition: Draw characters you can't type
• Massive dictionary database: Essential for serious language learners

6. Gaode Maps (高德地图) — Maps That Actually Work in China

Google Maps doesn't work reliably in China. Gaode (owned by Alibaba) is the most accurate mapping app. If you have an iPhone, Apple Maps also works — Apple uses Gaode's data.

Part Four: Cultural Etiquette — What to Do When Chinese People Are Being "Too Friendly"

The "Selfie With a Foreigner" Phenomenon

In smaller cities and rural areas, strangers may approach you and ask to take a photo with you. This is not rude. It is not racism. It is curiosity — for
