China Internet & Payment Guide: eSIM, Alipay, WeChat Pay

Who this pack is for

Foreign visitors arriving for a short stay — especially on the 240-hour (10-day) visa-free transit or a short unilateral visa-free visit — who need data and QR payments the moment they leave the airport. If you only want a price comparison of China eSIM plans, use our best eSIM for China guide. If you need the full app stack (maps, DiDi, 12306), see China apps for foreigners. Full entry-rule detail lives in the 240-hour visa-free entry guide.

Pre-arrival checklist

• Phone unlocked and eSIM-ready. Run our eSIM compatibility checker. Phones made and sold for the mainland Chinese market often cannot add a travel eSIM (Saily and others warn about this).
• Buy and install a China travel eSIM at home on Wi-Fi. Nomad and Saily say you cannot buy a new plan once you are already in mainland China. Follow the install guide; leave the travel line off until you land.
• Keep your home SIM / number active for SMS. Banks and payment apps send codes to the number you registered with.
• Install Alipay and WeChat (Weixin). Link a foreign bank card at home, where SMS and bank app approvals still work normally.
• Save hotel address in Chinese (screenshot or offline note) for taxis and the border form.
• Check your entry route on the NIA pages: 240-hour transit needs an onward ticket to a third country or region.
• Download offline maps / translation packs you may need if hotel Wi-Fi does not reach the apps you expect.

Travel eSIM for inbound visitors

A travel eSIM is international roaming on a Chinese partner network (providers name China Unicom, China Telecom or China Mobile). Airalo and Nomad say the data is carried to an internet gateway outside mainland China before it reaches the web, so the phone “appears as an international roaming user.” According to those providers’ official help pages, common apps such as Google, Gmail, Maps, WhatsApp, Instagram and Facebook can work on the travel eSIM’s mobile data. Always confirm against the provider’s current official statement — we have not speed-tested these claims ourselves.

1. 1

   Check compatibility

   Use the compatibility checker, then the provider’s own device list.

2. 2

   Buy before you fly

   Several providers say mainland China is not a place you can purchase a new travel eSIM after arrival.

3. 3

   Install on Wi-Fi at home

   Scan the QR or use the provider app. Keep the travel line off until you land so you do not burn validity early. Full steps: how to install an eSIM.

4. 4

   On landing, enable the travel line

   Turn on data roaming for the travel eSIM only; keep your home line for SMS if your phone supports dual SIM.

5. 5

   Test the apps you need

   Open maps, messaging and your payment apps on mobile data before you join hotel Wi-Fi.

Alipay and WeChat Pay with a foreign card

Day-to-day spending in mainland China runs on QR codes. Official visitor guides say foreign visitors can register Alipay or WeChat Pay with a foreign mobile number and link an overseas bank card without opening a Chinese bank account.

1. 1

   Install both wallets if you can

   Some merchants show only an Alipay QR or only a WeChat Pay QR. Having both avoids dead ends.

2. 2

   Register with your home phone number

   The NIA visitor guide says you can register with a foreign mobile number. Keep that SIM able to receive SMS.

3. 3

   Add your overseas bank card

   Follow in-app “Bank Card” / “Add card” flows. Your bank may send an SMS or push approval — easiest at home.

4. 4

   Complete any identity prompts the app shows

   Visitor flows vary by passport and version; follow the on-screen steps and the official English guides linked in Sources.

5. 5

   Make a tiny test payment before you travel if possible

   Or test immediately after landing on a small purchase so you are not debugging at a busy counter.

6. 6

   Carry a cash / card backup

   Not every stall takes foreign-card wallets, and banks can decline overseas transactions. Keep a small cash float and a physical Visa/Mastercard as backup.

When you need a phone number or SMS

• Payment-app registration and card linking — SMS to the number you registered with.
• Your home bank — fraud checks when the card is used in China or added to a wallet.
• Hotel, rail or attraction accounts — many still verify by SMS.
• eSIM provider support — account recovery may need email or SMS.

Practical approach: keep your home SIM active for SMS (or roaming SMS if that is cheaper than a full data roam), and use the travel eSIM for data. Dual-SIM iPhones and many Androids can do this. If your phone is single-SIM only, finish every SMS-gated setup before you swap lines.

240-hour visa-free transit essentials

From 17 December 2024, China unified earlier 72/144-hour transit policies into a 240-hour (10-day) visa-free transit (National Immigration Administration / www.gov.cn policy documents). Eligible ordinary-passport holders may enter at designated ports, stay in permitted areas, and must hold an onward ticket with a confirmed seat and date to a third country or region.

• Stay: up to 10 days (240 hours).
• Who: nationals of the countries listed on the NIA’s current announcement (the list has been expanded; for example Kyrgyzstan and Vietnam were added in 2026 — see Announcement No. 4 of 2026 on the NIA English site).
• Ports / areas: designated ports across multiple provinces; stay only in the permitted areas tied to the policy.
• Allowed purposes: travel, business, visits and family reunions — not work, study or news reporting without the proper visa.
• Separate scheme: many nationalities also qualify for up to 30 days unilateral visa-free entry (end dates vary; US passports are generally not on that list and often rely on the 240-hour transit or a visa).
