Quick answer: set up both apps before you fly
Install Alipay and WeChat from official app stores before departure, register with an international phone number where supported, and keep access to the phone used for verification. Prepare your passport, an eligible overseas card, a second payment card, and your card issuer’s contact details.
Complete the identity checks requested by each app, link a card, set a payment password, and make a small merchant payment before relying on either service. Carry a physical card and a modest amount of RMB cash as backup. Fees, supported cards, limits, menu labels, and available features can change, so check the current information in the apps and with your card issuer before traveling.
1. What to prepare before departure
Check your phone and number
Use an unlocked, updated phone and install both apps while you have reliable internet. Keep enough storage for app updates and make sure you can receive SMS messages abroad. This may require international roaming or another arrangement with your mobile provider.
Do not cancel the phone service connected to your accounts during the trip. If you change SIM cards, keep access to the original number if possible, or confirm how the apps handle account recovery before leaving home.
Prepare matching information
Keep your passport available for identity verification. Enter your name and other personal details exactly as they appear on the relevant documents and card records. Differences in spelling, order, or billing information can cause an automated check or card-linking attempt to fail.
Your card issuer should also know that you may use the card abroad. Confirm that international, online, and mobile-wallet transactions are permitted. Save the issuer’s fraud and emergency contact details somewhere you can access without the banking app.
Pack payment backups
Bring at least one physical card and preferably a second card from another account or payment network. A small RMB cash reserve is useful for transport, small purchases, outages, or a merchant that cannot process your app payment. Cash and cards are backups, not substitutes for checking the payment options available at your destination.
2. Set up Alipay and WeChat Pay
A foreign visitor may be able to use an overseas card for merchant payments without opening a Chinese bank account. That does not mean every wallet function is available. Transfers, red packets, balance top-ups, and other domestic features may have different requirements.
Alipay
- Register using your international mobile number or the registration option currently shown in the app.
- Open the account, identity, or verification area and follow the passport-verification instructions.
- Add an eligible overseas card through the wallet or payment settings.
- Complete any extra authentication requested by your card issuer or the app.
- Create or confirm a payment password and review the security notifications.
The exact labels and location of these settings may change. If the app offers a choice between adding a card and loading a balance, read the description carefully. Foreign-card merchant payments do not necessarily work in the same way as a locally funded wallet.
WeChat Pay
- Create or use a WeChat account with an international number where registration is supported.
- Open the Wallet or Services area and follow the current prompts for payment setup.
- Complete the identity check requested by the app, which may involve passport information.
- Add an eligible overseas card and complete any bank or app authentication step.
- Set a payment password, then close and reopen the app to confirm that you can access the wallet.
Foreign-card WeChat Pay accounts may not offer every feature available to users with a domestic account. Treat successful merchant-payment setup as separate from the ability to send money to another person or use other wallet services.
3. Understand QR-code payments
Chinese merchants commonly use one of two QR payment flows.
In the first, you scan the merchant’s QR code with Alipay or WeChat. The app identifies the merchant and asks you to confirm the amount and payment method. In the second, you open your payment code and let the merchant scan it. The available flow depends on the merchant and the app.
Before approving a payment, check the amount, currency, and card selected as the funding source. Keep the transaction record or receipt until the purchase is settled. Do not scan an unfamiliar code without checking what it is requesting.
A successful setup does not guarantee that every merchant will accept both apps. Acceptance can differ between cities, transport services, chain stores, market stalls, small restaurants, and rural destinations. Some services may require a separate mini program or account function that is not available to every foreign visitor.
4. Make a first-day payment test
Test both apps with a low-value purchase at a staffed merchant rather than making your first attempt during an urgent journey or a large transaction. A small test can show whether the card is linked, the payment password works, the phone has a usable connection, and the merchant accepts that app.
Check the transaction record after payment. If the charge is pending, duplicated, reversed, or shown in an unfamiliar currency, avoid repeatedly paying until you understand the status. Contact the relevant app or card issuer if the issue remains unclear.
Before departure, verify current information about foreign-card support, fees, transaction thresholds, limits, and any exchange-rate or issuer charges. These details can vary by app, account, card, and location.
5. Troubleshooting checklist
| Problem | What to check and try |
|---|---|
| Verification SMS does not arrive | Confirm the country code, roaming, signal, and phone number. Wait before requesting another code and use another verification method if the app offers one. |
| Overseas card is rejected | Check international and online payments with your issuer, confirm that names and billing details match, and try the backup card. |
| Passport verification fails | Use a valid, clear document and accurate matching details. Retry in good lighting and contact in-app support if the prompt continues. |
| QR payment fails | Check the data connection, reopen the app, confirm the selected card, and try the other app or a physical payment method. |
| Payment is blocked or limited | Read the in-app message, avoid repeated attempts, and contact the app or card issuer while using a backup method. |
| Phone is lost or replaced | Use account-recovery and device-security procedures, contact your mobile carrier and card issuer, and keep offline recovery details available. |
A card that works in Alipay may not work in WeChat Pay, and the reverse can also happen. The difference may relate to the card issuer, app risk checks, account status, or the particular merchant. Do not assume that repeated retries will fix the problem.
6. Build a practical backup plan
Before leaving your accommodation each day:
- Confirm that both apps are logged in and the phone has enough battery.
- Carry your physical backup card separately from your phone.
- Keep a modest amount of RMB cash in a secure place.
- Save your bank, accommodation, insurer, and emergency contacts offline.
- Carry a power bank for long rail journeys, road trips, rural stays, and busy sightseeing days.
- Keep an offline copy of your passport details and relevant booking information, stored securely rather than publicly on the phone.
If your phone has no data connection, app payments may not work as expected. If the phone battery is empty, neither QR flow is available. A physical card or cash may solve the immediate problem, although acceptance is not universal. Plan for a short period without mobile payment instead of carrying only one digital option.
Pre-departure and first-day checklist
- Install and update Alipay and WeChat.
- Register the accounts and retain access to the phone number used.
- Complete the passport or identity checks requested by each app.
- Link and authenticate an overseas card in both apps.
- Set payment passwords and review security alerts.
- Make a small test payment where practical.
- Pack a second physical card and RMB cash.
- Save card-issuer and app-support contacts offline.
- Recheck current fees, supported cards, limits, and merchant-payment requirements before departure.
FAQs
Should I set up Alipay, WeChat Pay, or both?
Set up both if your phone and travel plans allow it. Alipay may be convenient for some visitor services and transport-related functions, while WeChat is widely used for communication and services connected to its ecosystem. Neither app is guaranteed to work at every merchant, so having both reduces dependence on one account.
Can I use a Visa or Mastercard issued outside China?
An overseas Visa or Mastercard may be eligible for merchant payments, but support depends on the current app rules, your card issuer, account verification, and the merchant. Check the app’s current card requirements and ask your issuer whether the card permits international and mobile-wallet transactions.
Do I need a Chinese phone number?
Not necessarily for every registration route, but an international number must be supported by the current app process and remain accessible for verification or recovery. Confirm the country code, roaming arrangements, and any alternative verification method before departure.
Can foreign visitors use QR codes at taxis, convenience stores, and small restaurants?
Sometimes, but acceptance and payment flows vary. A merchant may accept only one app, use a separate service, or have a code that does not support your account type. Ask before ordering when possible and keep a card or cash backup.
What if my card works in one app but not the other?
Use the working app for eligible merchant payments, check the rejected app’s message, and contact the card issuer if necessary. Confirm that your personal and billing details match, then try the second card rather than repeatedly submitting the same failed transaction.
