Yes — Wi-Fi at Singapore Changi Airport is free across all terminals. Connect to the network named #WiFi@Changi, open a browser to bring up the sign-in page, and click the Wi-Fi logo to get online. It works in both public (landside) and transit (airside) areas of every terminal. Sessions are commonly capped at about three hours, but you can reconnect.
How to connect, step by step
- Open your device's Wi-Fi settings and select #WiFi@Changi.
- Open your browser (Safari, Chrome, Firefox, etc.) and visit any website to trigger the sign-in page.
- Click the Wi-Fi logo on the page to start your free session.
- If your session ends, simply reconnect to keep browsing for the rest of your stay.
Some sign-in flows for international visitors may ask for a mobile number to send a one-time code (OTP), or you can use a passport-based option at a kiosk. The exact sign-in steps and any verification requirement should be verified officially on arrival, as they can change.

The three-hour session figure comes from traveller reports rather than the official page, so treat it as unconfirmed and verify it officially before you rely on it.
Watch out for fake networks
The official network is named #WiFi@Changi. Treat look-alike names (for example one promising "unlimited free" access from an unknown provider) with caution. On any public Wi-Fi, avoid logging into banking or entering card details unless the site is secured (https), and consider a VPN for sensitive tasks.
Best for whom
- Short layovers: connect once, message ahead or check your gate — the session cap rarely matters for quick tasks.
- Remote workers on a long transit: fine for email and browsing; for long video calls or large uploads, the periodic reconnection and peak-time load mean a mobile data plan or eSIM may be steadier.
- Anyone out of battery: use the free internet kiosks and charging points in the terminals.
Wi-Fi setup, network names and session rules can change. Confirm the latest on the official page before you rely on it: Changi Airport — Free WiFi and Internet Connection. See also our Changi transfers guide and Changi lounges guide. Last reviewed: June 2026.
