Questions
Should I buy a SIM at Singapore Changi or an eSIM before I fly?
An eSIM installed at home is working the moment the plane's door opens: no queue at the airport SIM counter, no passport registration at the kiosk, no hunting for a shop after a long flight. Install it on wifi before departure, switch it on when you land.
Which networks will the eSIM use in Singapore?
It connects to M1, SingTel, StarHub or TPG Telecom (up to 5G), picking the strongest signal automatically, including inside the terminal.
When should I install it?
Before you fly, on wifi. The plan's validity starts when the eSIM first connects to a network in the destination, not when you install it, so installing early costs nothing.
Do I keep my own number?
Yes. The eSIM is data only. Your home SIM stays in the phone for calls, texts and bank codes; turn off data roaming on it so it is not used by mistake.
