WiFi & Connectivity
Stay connected at Chengdu Shuangliu International Airport — free WiFi, eSIM options and local data for China.
Airport WiFi at CTU
Registration required to connect — look for the sign-in page after joining the network.
China's firewall blocks Google, WhatsApp, Instagram, and most Western apps over local wifi or a Chinese SIM without a VPN — but a foreign data eSIM (roaming on a home-country or third-country network) routes around the block entirely, so Maps and WhatsApp keep working normally. Buy the eSIM before you land rather than counting on downloading a VPN app once you're on Chinese networks.
Free wifi login requires SMS verification to a mobile number, and travelers repeatedly report that non-Chinese numbers often don't receive the code — don't burn time troubleshooting it; your own eSIM data will get you online faster and sidesteps the firewall issue entirely.
