Quick answers
Common questions
Is airport Wi-Fi enough for the first day?
Usually not. Captive portals, weak coverage and login friction make it unreliable for payment and transport apps.
Should I buy a local SIM or use an eSIM?
An eSIM installed before departure is usually smoother. Keep a local SIM purchase plan as backup if the eSIM fails.
What usually works for visitors
Most independent travelers use a travel eSIM installed before departure, a local SIM bought at the arrival airport, or a hotel/companion hotspot as a temporary bridge. Airport Wi-Fi alone is a weak primary plan.
Before you leave
- Install and activate an eSIM that covers mainland China data.
- Confirm the plan works by disabling Wi-Fi and loading a map.
- Save the hotel Chinese address and phone number offline.
- Write down where you can buy a local SIM if the eSIM fails.
When a plan fails on arrival
Use offline hotel details to reach staff or a taxi desk first. Restore data before relying on Alipay, WeChat Pay or ride-hailing. Keep a second connectivity option ready rather than troubleshooting one route indefinitely.
