Absolutely. We recommend installing your Truly Roaming eSIM for Singapore before you even board your flight. The plan will remain dormant until your device registers with a local network upon landing. This means you’ll have instant connectivity for navigation, ride-sharing apps, or urgent messages as soon as you touch down at Changi Airport, without scrambling for airport Wi-Fi.
