Changi Airport eSIM and Wi-Fi guide
How to get online at Singapore Changi Airport and prepare an eSIM before leaving the terminal.
Before you land
Confirm that your phone is unlocked and eSIM-compatible. Buy the plan you need, keep the installation details available offline, and follow the provider instructions about when to install or activate it.
At Changi Airport
Changi Airport says #WiFi@Changi is available free in public and transit areas. Use that connection to retrieve your eSIM details if needed, but avoid entering sensitive information on public Wi-Fi unless you trust the connection.
Before leaving the terminal
Select the travel eSIM for mobile data, keep your home SIM selected only for the services you need, and review data-roaming settings. Test a webpage before relying on maps or transport apps.
