FAQ
Does a Hong Kong plan work in Macau?+
Not always — they are separate coverage areas. If you plan to cross over, pick a plan that lists both, or an Asia regional plan.
When does a Hong Kong eSIM start counting days?+
Most plans here start when the phone first connects to a network at the destination, so you can install in advance at home and switch it on after landing. Each plan page states its own rule.
Do I have to remove my home SIM?+
No. The eSIM is a second line, so you keep your home number for SMS OTP. Turn off roaming data on the home line and set the eSIM as the data line.
