Absolutely! We recommend installing your SouthESIM for Singapore before you even board your flight. It’s a smart way to ensure you're connected the moment you touch down at Changi Airport. Your data plan won't actually start counting down until your device detects and connects to a network in Singapore. So, you can activate it from home, relax on your flight, and then seamlessly start sharing your adventures from the moment your feet hit the ground in this vibrant city.
