Foreign visitors can buy a physical China SIM card at an official staffed carrier outlet using a valid passport; a Chinese national ID is not normally required. Confirm that your phone is unlocked, ask the carrier to complete real-name registration, and test the plan before leaving the counter. Beijing Capital, Beijing Daxing and Shanghai Pudong publish airport SIM services, but check your terminal, opening hours and stock before relying on an airport purchase. A travel eSIM or home roaming can be an arrival backup if your phone and plan support it.

Buy a physical China SIM with a passport
Where
What to bring or verify
If unavailable
Official China Mobile, China Unicom or China Telecom outlet
Original passport, unlocked phone, plan details and total price
Try another staffed branch or use roaming until one opens
Beijing Capital or Daxing airport service counter
Official Beijing guidance lists airport SIM services; confirm the exact terminal, counter and hours
Use an official city outlet after arrival
Shanghai Pudong international traveler service center
Official Shanghai guidance describes short-term China Telecom SIM service with passport ID
Keep a travel eSIM or roaming backup
Ask whether the plan includes a Chinese +86 number, voice and SMS, how much high-speed data it contains, when it expires and how to top up. Do not infer the price or included service from another airport or city.
Have the staff complete identity registration and activate the SIM, then test mobile data and a required SMS before leaving. An airport service listing does not guarantee your arrival-time availability or your phone model compatibility.
eSIM vs physical SIM at the airport
Option
Useful when
Important limitation
Travel eSIM
You want data ready soon after landing
Requires an unlocked, eSIM-compatible phone and is often data-only
Physical mainland SIM
You need a Chinese number for calls, SMS, or local services
Requires passport registration and remains subject to mainland internet controls
Home-carrier roaming
You need the simplest arrival backup
Can cost more; allowance and international-service access vary by carrier
Install a travel eSIM before departure on reliable Wi-Fi, but follow the provider's instructions about when validity begins. Do not assume every eSIM includes a Chinese phone number or unrestricted access to international services.
For a physical SIM, use an official staffed carrier counter or store. Avoid an unregistered SIM sold informally because real-name registration, ownership, support, and replacement may be unclear.
Dual-SIM travelers can often keep the home line active for verification SMS while using the China line for data. Disable home-line data roaming unless your home plan explicitly includes it.
China Mobile, China Unicom, and China Telecom compared
Carrier
Practical strength
Check before paying
China Mobile
Large nationwide network and broad retail presence
Confirm your phone supports the plan's required network bands
China Unicom
Often considered by visitors using international handsets
Verify coverage for rural destinations and the exact prepaid plan
China Telecom
Another major nationwide option with city and regional coverage
Device and network compatibility can vary, especially on older imported phones
Coverage differs by destination, building, route, and device. Ask the counter to verify your phone model and test mobile data before you leave.
Compare the included high-speed data, domestic calls, validity, renewal rules, hotspot support, and what happens when the allowance is used.
English support varies by branch. Keep your destination list in Chinese and ask the hotel which carrier works reliably in any rural area on your route.
How to buy at an official carrier counter
At an airport, check the official service directory and ask the information desk for a staffed SIM counter. Beijing Capital, Beijing Daxing and Shanghai Pudong publish visitor services; for other airports, confirm a counter before travel. Locations, opening hours and stock can change.
Present the original passport you used to enter China. The carrier may photograph or scan the document and your face to complete legally required real-name registration.
Show the trip length, cities, expected data use, and whether you need a Chinese number, voice calls, SMS, hotspot use, or only mobile data.
Ask the staff to confirm the total price, included allowance, validity, top-up method, and whether the number expires or enters a grace period after the plan ends.
Insert or activate the SIM at the counter. Test data, one website, maps, and any required SMS before leaving. Save the carrier receipt, plan name, phone number, and support number.
If the airport counter is closed or unavailable, keep roaming or eSIM data active and visit an official staffed carrier store in the city with your passport.
How to top up with Alipay
Open Alipay and search for mobile top-up or phone recharge, then enter the Chinese mobile number carefully.
Confirm the carrier and number shown before choosing an amount. A mistaken top-up may be difficult to reverse.
Review the funding source and final amount. An international card linked to Alipay may not support every recharge product or transaction.
Keep the carrier app, official store, staffed counter, or another supported payment method as a backup. Save the top-up receipt until the balance appears.
Do not share a payment PIN, SMS code, or passport image with an informal seller offering to recharge the number.
VPN, Alipay, and WeChat Pay: what to prepare
Ordinary mainland SIM data is subject to local internet controls. Some international roaming and travel eSIM plans route traffic differently, but this depends on the exact provider and plan.
If you intend to use a VPN or similar service, check current rules and install only a trusted, legally compliant service before departure. A China SIM does not itself provide unrestricted internet access.
Set up Alipay and WeChat Pay before departure while you can receive verification messages from your usual number. Linking an international card and passing identity checks are not guaranteed for every user or transaction.
Alipay and WeChat Pay do not normally require a VPN for domestic payment functions. Keep a physical card and some RMB cash because wallet, card issuer, merchant, or connectivity failures can still occur.
Save the hotel address, first transfer, tickets, essential contacts, and key Chinese phrases offline so one connection or payment failure does not block the arrival plan.
FAQ
Can foreigners buy an eSIM for China?
Yes. Foreign visitors can buy a travel eSIM that covers mainland China if their phone is unlocked and eSIM-compatible. Check whether the plan is data-only, when validity starts, which network it uses, and whether required international services work. Install it before departure and keep the activation details offline.
Do I need a Chinese ID to buy a SIM card in China?
A foreign visitor normally uses an original passport instead of a Chinese national ID at an official staffed carrier counter. The carrier must complete real-name registration and may scan the passport and take a photo. Requirements, available prepaid plans, airport stock, and opening hours can vary by location.
Can I keep my existing phone number while using a China SIM?
Usually yes if your phone supports dual SIM or eSIM plus a physical SIM. Keep the home line active for important verification messages, select the China line for mobile data, and disable home-line data roaming unless included. Check whether receiving calls or texts on the home line creates charges.
