How to connect to #WiFi@Changi
WiFi at Changi is free in both the public and transit areas of all four terminals and at Jewel. There is no time limit published on the official site, no registration, and no need to enter an email or phone number — a refreshingly frictionless setup compared with most major airports.

On the login page, click the WiFi logo to start browsing. No password is required.
Tip: The captive portal can occasionally be slow to appear. If it does not, navigate to a non-HTTPS URL (for example http://neverssl.com) to force the redirect, or open the Changi App which can trigger the login flow.
How fast is it, really?
Changi does not publish an official speed figure, so any page quoting a single precise number is making it up. Independent tests tell a more honest story:
- Ookla / Hardwarezone: averaged ~97 Mbps download, ~114 Mbps upload in one published test.
- Simology field tests: 70–160 Mbps download, 10–35 Mbps upload, with a ~1-second captive-portal delay.
- testmy.net logs: averaged ~25 Mbps — lower, reflecting busier periods.
In practice, expect comfortably usable browsing and video streaming, with speed depending heavily on how crowded your terminal is. For guaranteed bandwidth for a video call, a paid lounge or the JustCo centre below are safer bets.

Are the charging points safe?
A common and reasonable worry at public USB ports is "juice-jacking" — hidden data connections that could compromise a phone. Changi addresses this directly: charging ports across Singapore Changi Airport and Jewel Changi Airport are charge-only and will never request data transfer to or from your device. Universal power sockets are also provided for laptops and other plugs.
- Bring your own cable — Changi does not provide cables for security reasons.
- All charging points are free, for all passengers, with no time limit — just be considerate during busy periods.
- Do not leave devices unattended. Approach airport safety and security staff if you have concerns.
Where to work or sleep
There is no free dedicated co-working space at Changi. Terminal 3 hosts a JustCo pay-per-minute co-working centre — Asia's first in an airport — with 50 hot-desk workstations, private offices, meeting rooms, and quiet nooks. For free rest, the Snooze Lounges below are open 24/7 in the transit area.
