Questions
Should I buy a SIM at Hong Kong International 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 Hong Kong?
It connects to csl, SmarTone, 3 or csl/1010 (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.
