Travelling to China is easier when connectivity is prepared before departure. This guide focuses on practical steps that reduce arrival-day problems and help you stay reachable for study, travel, or business.
At the arrival gate
After landing, turn off airplane mode, enable the selected eSIM line, assign it as the mobile-data line, and turn on data roaming if the instructions require it. Give the device a few minutes to register. If it does not connect, restart the phone once and check automatic network selection before changing advanced settings.
Before leaving the terminal
Confirm that messaging, maps, and the ride-hailing or transport app you plan to use can load. Send a short message to family, copy your destination into the transport app, and take a screenshot of the route. Airport Wi-Fi can be useful for setup, but it may require verification and should not be your only arrival plan.
During the journey home
Keep battery use under control by lowering screen brightness, closing unnecessary background apps, and using low-data mode if needed. Avoid large system updates or cloud backups while travelling. When using public transport, retain a screenshot of the station name and transfer instructions in Chinese.
If the network is unstable
Do not repeatedly scan the QR code or delete the eSIM. Check whether the plan is selected for data, whether roaming is enabled, and whether the phone has connected to a supported network. Move away from underground or enclosed areas before concluding that setup failed. Contact support with the order number, device model, current location, and screenshots of cellular settings.
Before buying an eSIM
Confirm that your device supports eSIM, is carrier-unlocked, and matches the compatibility information on the product page. Review the plan's destination coverage, validity, activation timing, hotspot policy, and current app-access information. Product terms can change, so the product page and order instructions should be treated as the current source of truth.
