You'll want both: Alipay as your everyday payment app, WeChat Pay as the backup some vendors insist on. The setup is the fiddly part — this walks you through it before you fly, when you have time and signal.

The rule in one line Do the whole setup at home. Download, register, bind your card and verify — four steps per app — while you still have your home network and a friend nearby to help.
Illustrations, not screenshots The phone pictures on this page are simplified illustrations showing which button to tap, not the real app. Exact screens differ by version and country — follow the words, not the pixels.

Part 1 — Alipay

Step 1 · Download Alipay

Search "Alipay" in the App Store or Google Play. It's a free app by Ant Group. If your store shows a Chinese-only version, look for the international one with English support.

Step 2 · Register with your number

Open the app and sign up with your home phone number. Set the country code to your country — your own number is fine, it doesn't need to be Chinese.

Step 3 · Add your card

Go to Account → Add card and enter your Visa or Mastercard. You may be asked to complete real-name verification with your passport — this is normal and required for foreign cards.

Step 4 · Verify & test

After your card binds, do a tiny test payment — even a small transfer confirms the whole chain works before you're standing at a counter abroad.

Part 2 — WeChat Pay

Step 5 · Download WeChat

Search "WeChat" in the App Store or Google Play — it's the green messaging app by Tencent. You're installing it for payment, but it's also the messaging app everyone in China uses.

Step 6 · Register

Sign up with your home phone number and set a password. WeChat may ask you to verify with an SMS code — have your phone handy.

Step 8 · Verify — sometimes a friend helps

WeChat occasionally asks an existing user to scan a QR to confirm your identity. If it does, do it at home with a friend who already has WeChat — this is the step that catches people out at a counter abroad.
