A Beijing airport eSIM is normally purchased and installed before the flight, not from an airport eSIM counter. Once you land at Beijing Capital (PEK) or Beijing Daxing (PKX), you turn on the prepared travel line and connect to a partner mobile network.
Preparing in advance is useful when you need data immediately for an address, translation, ride-hailing, train information or a hotel message.
NoveSIM travel eSIMs are data-only and do not provide a Chinese number, conventional calls or SMS.
Quick answer: Install the China eSIM on reliable Wi-Fi before flying. At PEK or PKX, select it for Mobile Data, enable Data Roaming on that line, keep network selection on Automatic and test a normal webpage before leaving the terminal.
Top China eSIMs
PEK and PKX are different airports
Beijing Capital International Airport uses the code PEK. Beijing Daxing International Airport uses PKX. Confirm the code on the booking because the airports have different terminals, transport links and journey times.
The eSIM setup itself is the same at either airport, provided the selected plan includes mainland China and the phone can connect to an available partner network.
Prepare before departure
- Confirm that the phone is unlocked and supports eSIM.
- Choose a plan that explicitly includes China.
- Read when validity begins.
- Install the profile on stable Wi-Fi.
- Label the line China Data.
- Save the hotel address, airport code and transfer details offline.
If you need the complete QR-code sequence, use the China eSIM setup and usage guide before travelling.
Connect after landing
- Turn off Airplane Mode when permitted.
- Open the SIM or cellular settings.
- Turn on the China eSIM.
- Select it for Mobile Data.
- Enable Data Roaming for the China line.
- Disable automatic data switching.
- Leave network selection on Automatic and wait for registration.
- Open a standard webpage to test the connection.
Do not judge the eSIM only by whether one international app opens. Mainland China app access can differ from basic internet connectivity.
eSIM, airport Wi-Fi or a physical SIM?
| Option | Practical use on arrival |
|---|---|
| Pre-installed travel eSIM | Mobile data can start after network registration |
| Airport Wi-Fi | Useful as a temporary connection; login or verification may be required |
| Physical local SIM | May suit travellers who need a local number and can complete registration |
| Home-carrier roaming | Convenient but dependent on the carrier’s China pricing |
For public-network login and connection help, see the dedicated Beijing airport Wi-Fi guide. Travellers considering a physical card can compare the process in the Beijing airport SIM guide.
Current arrival options at PEK and PKX
Beijing’s official guidance states that free Wi-Fi is available throughout both airports. Authentication can still be part of the connection process, so keep the exact Wi-Fi instructions available and do not depend on an unverified network name. Airport Wi-Fi is most useful for a short arrival task or as a backup while the eSIM registers.
Official Beijing arrival guidance also lists SIM vending machines and staffed counters at both airports. A local physical SIM can provide a Chinese number, but purchase and identity-registration requirements apply, and the available stock, counter location and opening hours can change. Confirm the service after landing instead of planning around a guaranteed counter.
A pre-installed eSIM avoids the airport purchase step, but it does not provide a local Chinese number. Choose between the options according to whether you need immediate data or a domestic number for the rest of the trip.
Before leaving the terminal
- Load the full hotel or accommodation address.
- Check the correct airport and terminal in the transport booking.
- Message the hotel or driver while the connection is stable.
- Download the first route for offline use.
- Check the phone’s battery before beginning the transfer.
For connectivity beyond the terminal, compare eSIM, local SIM and roaming in the broader China mobile-data guide.
If the eSIM does not connect
- Confirm that the plan is active and includes China.
- Check the mobile-data line and roaming setting.
- Toggle Airplane Mode once.
- Keep network selection on Automatic.
- If manual NoveSIM APN entry is required, use data.esim.
Do not delete the profile. Follow the China eSIM troubleshooting guide or contact support from airport Wi-Fi.

FAQ
Can I buy an eSIM after landing at Beijing Airport?
You can purchase online when you have internet access, but installing before departure is safer and avoids depending on airport connectivity.
Does the same China eSIM work at PEK and PKX?
It can, provided the plan includes China, the phone is compatible and an included partner network has coverage at the airport.
Do I need airport Wi-Fi to activate the eSIM?
Not when the profile is already installed and only needs mobile-network registration. Keep Wi-Fi available as a backup.
What should I do if the eSIM shows signal but no data?
Check the selected data line, roaming, plan status and APN. Do not delete the profile during troubleshooting.
Final Recommendation
Prepare the China eSIM before flying and confirm whether your booking arrives at PEK or PKX.
After landing, use the travel line for data, enable roaming on that line and keep the home SIM from switching to mobile data.
Test the connection and load the first transfer route before leaving the terminal.
