We recommend scanning your EastESIM QR code and installing the profile before you even depart for Singapore. Doing this while you still have a reliable internet connection at home ensures a smooth setup process. The eSIM will only activate its data plan once it connects to a supported network in Singapore, like Singtel or StarHub. This way, the moment you land at Changi Airport (SIN), your EastESIM will seamlessly connect, allowing you to instantly book a Grab or navigate to your hotel without hunting for Wi-Fi.
