China SIM Card: Use a Staffed Carrier Office
Use the official staffed-office and original-passport route for a China SIM without relying on an airport kiosk or reseller promise.
The narrow official route is to take your original passport to a staffed service office operated by China Mobile, China Unicom, or China Telecom and apply for a SIM there. Real-name registration applies. Airport kiosks, resellers, online stores, and vending machines may not process a foreign passport. Let the operator confirm the current plan and price.
Do the three stepsUse an operator-run staffed office
Bring the original passport and an unlocked phone with a compatible physical SIM tray. Ask the office to confirm the current plan, identity step, number, data, calls, validity, top-up route, and support before payment.
Do these three things
These three actions cover the normal path. Special cases and deeper detail follow below.
- 1
Check the phone first
Confirm that the phone is unlocked, has the correct physical SIM tray, and supports the carrier bands needed for the chosen service.
- 2
Bring the original passport
Go to a staffed China Mobile, China Unicom, or China Telecom service office with the original document; a scan or copy is not an established substitute.
- 3
Confirm the full plan before paying
Ask about the number, data, calls, validity, top-up, cancellation, and support route. Save the plan name and branch details.
Where should you try to register the SIM?
Foreign-passport processing is the key condition. A convenient seller is not useful if it cannot complete the identity step.
Use an operator-run service branch
Bring the original passport and ask staff to confirm the current plan and registration route.
Confirm passport support before paying
Verify that the seller can register a foreign passport. Leave if the identity or ownership route is unclear.
Use an existing travel connection
Keep confirmed roaming or a checked travel eSIM when a local number is not needed for the tasks on this trip.
You are ready when...
- The phone is unlocked and has a compatible physical SIM tray.
- The original passport is available for real-name registration.
- You know which operator-run staffed office you will try first.
- Roaming, a travel eSIM, or trusted Wi-Fi covers the time before activation.
Special cases and detailed steps
Use these sections when the normal path does not fit your conditions. They cover exceptions, extra checks, and longer recovery steps.
Treat registration as the main task
The current government route is simple but specific: take the original passport to a staffed service office of China Mobile, China Unicom, or China Telecom. The operator checks identity information before opening service.
This does not prove that every airport desk, reseller, website, or machine can complete the same foreign-passport process.
Check the phone before visiting a branch
Confirm that the phone is unlocked and has a compatible physical SIM tray. Device band support and the plan offered by the branch can still affect service.
Keep the current line installed until the new SIM works. If the phone uses only eSIM, do not buy a physical card without checking how it can be used.
Ask for the complete plan in plain terms
Before payment, ask staff to show the plan name, local number, data, calls, validity, top-up route, renewal or cancellation rule, and official support channel. Do not use an old blog price as the final amount.
Save the branch name and plan details. They will be more useful than a generic instruction if account support is needed later.
Keep a connection before and after the visit
Use confirmed roaming, a checked travel eSIM, or trusted Wi-Fi until the SIM is active. Save the hotel address and branch name in Chinese before leaving Wi-Fi.
If the first seller cannot process the passport, do not hand over extra documents or accept a card registered in another person's name. Move to an operator-run staffed office.
If something does not work
Match the issue to one recovery step, then move to the backup when time matters.
The airport seller cannot register your passport
Do not force the sale or accept an unclear ownership route. Use a staffed branch operated by one of the three named carriers.
The branch asks for the original document
Present the original passport. The current official route supports passport-based registration and does not establish that a photo or paper copy is enough.
The phone does not detect the SIM
Ask staff to check the SIM, tray, lock state, and device compatibility before changing network settings. Keep the backup connection active.
The plan details differ from an online post
Use the current operator information at the branch. Confirm the price, data, calls, validity, top-up, and cancellation before paying.
If a kiosk or reseller cannot complete foreign-passport registration, leave without sharing extra documents and go to an operator-run staffed office. Until activation is complete, use confirmed home roaming or an already installed travel eSIM plus trusted hotel or airport Wi-Fi. Keep the hotel address in Chinese and the original passport with you.

Recheck when it matters: Recheck the official government guide and the chosen carrier's current service channels. Confirm the branch location and hours directly with the operator. Plans, prices, foreign-passport handling, inventory, language support, validity, and top-up methods can vary by branch and date.

Frequently asked questions
Can a foreign visitor buy a SIM card in China?
The current government guide says a foreign visitor may take a passport to a service office of China Telecom, China Mobile, or China Unicom to apply for a SIM and activate service.
Can I use a passport copy instead of the original?
Do not rely on that. The source-backed route is to bring the passport, and the operator notice describes checking original valid identity documents.
Will every airport kiosk sell me a registered SIM?
No such guarantee is supported. A kiosk, reseller, or vending machine may not be able to process a foreign passport. Use an operator-run staffed office as the reliable route.
What plan and price should I expect?
Plans vary by operator and can change. Confirm the current data, calls, number, validity, top-up, price, and support at the staffed office before payment.
