eSIM at Changi Airport (SIN)
The biggest advantage of an eSIM is that travelers arrive already connected, skipping the airport SIM counter entirely. Install the Simbye Singapore eSIM before departure; it activates on first connection to a Singapore network, so the data does not start early.
- Changi Airport (SIN): Install the Simbye eSIM at home on WiFi, or connect using free airport WiFi after landing. A pre-installed Simbye eSIM connects the moment the plane lands, so there is no need to find a SIM card shop in the arrivals hall.
Pro tip: Install the Simbye eSIM at home on WiFi before the flight. The Simbye eSIM stays dormant until travelers arrive in Singapore and connect to a local network — zero setup needed at the airport.
How to install a Singapore eSIM
Installing the Simbye Singapore eSIM takes under two minutes on any eSIM-compatible phone (iPhone XS or newer, and most Android phones from 2020 onward, per the GSMA eSIM standard).
- Buy the Simbye Singapore eSIM and receive a QR code by email and in the Simbye app.
- On iPhone, open Settings → Cellular → Add eSIM and scan the QR code. On Android, open Settings → Network & internet → SIMs → Add eSIM.
- Enable data roaming for the Simbye line (this only allows the eSIM to connect to the Singapore network; it does not incur home-carrier roaming charges).
- Leave the Simbye eSIM installed but inactive until you land in Singapore — the data activates on first connection.
Troubleshooting your Singapore eSIM
- No service after landing: Toggle Airplane mode on and off, then confirm the Simbye line is set as the data line and roaming is enabled.
- Data not working: Check that the APN is set automatically and that the Simbye line — not the home line — is selected for cellular data.
- QR code already used: An eSIM QR code can only be installed once. Reinstall from the Simbye app, which stores the profile for re-download.
