For the smoothest start to your Singaporean adventure, we recommend activating your EastESIM QR code before you even board your flight. This way, your eSIM will be active and ready to connect the moment you land at Changi Airport. You can immediately use apps like Grab for transport, check out directions to your hotel near Marina Bay Sands, or update loved ones on your safe arrival, all without the hassle of finding public Wi-Fi or searching for a physical SIM card.
