Airport WiFi at CSX
Registration required to connect — look for the sign-in page after joining the network.
Mainland China's Great Firewall blocks Google, WhatsApp, most Western social media, and many other everyday apps and sites, regardless of whether you're on airport Wi-Fi or a data eSIM — bring a VPN installed and tested before you arrive if you need those services, since VPN provider sites are often themselves blocked once you land.
Registration usually requires a Chinese phone number for SMS verification, which foreign visitors often can't complete — if the portal won't accept your number, look for a lounge (which typically has open access) or just wait for hotel Wi-Fi.
