Landing in China without working mobile data can make airport pickup, hotel contact and onward transport difficult. In most cases, the problem can be narrowed down by checking the eSIM status, selected data line, roaming setting and network registration in a fixed order.
First, connect to reliable Wi-Fi
Use airport, lounge or hotel Wi-Fi temporarily. Avoid repeatedly deleting or reinstalling the eSIM. A deleted eSIM may require a replacement QR code, and the original code may not be reusable.
Check these settings in order
- Confirm the eSIM is installed: it should appear under mobile or cellular plans.
- Turn the line on: the eSIM must be enabled before it can connect.
- Select it for mobile data: the phone may still be using the original SIM.
- Enable data roaming: many travel eSIMs require this setting even though the package itself already covers the destination.
- Check the APN: use the APN provided with the plan, when one is required.
- Use automatic network selection first: allow the device time to register.
- Restart the phone: this can force a new network-registration attempt.
Why the phone may show no signal
Common causes include early activation before the coverage period, an unsupported phone model, a carrier-locked device, incorrect data-line selection, disabled roaming, incomplete APN settings or temporary weak coverage inside the airport.
Move to an open area before concluding that the plan failed
Large terminals, underground rail links and enclosed pickup areas can affect reception. After checking the settings, move closer to a window or outside the terminal and allow several minutes for network registration.
Do not make these mistakes
- Do not scan the same QR code on multiple phones.
- Do not delete the eSIM before contacting support.
- Do not enable mobile data on the original SIM unintentionally.
- Do not assume that installation and activation are the same event.
- Do not wait until an urgent pickup problem occurs before saving support information.
Prevent the problem before the next trip
Install the eSIM on stable Wi-Fi before departure, take screenshots of the instructions, confirm device compatibility and keep the purchase details accessible offline. Travelers who depend on immediate connectivity should also keep a backup payment method and a second connection option.
