Questions people ask about Japan
01
When does the clock start?
At the first connection to a network in Japan, not at purchase. Buying weeks ahead costs you nothing.
02
Do I keep my own phone number?
Yes. A zoesim adds a data line beside your usual SIM. Calls and bank codes still arrive on your own number.
03
When should I install it?
Before you leave, on your own wifi. Installing needs a connection; using it later does not.
04
What happens when the data runs out?
The connection stops rather than billing you extra. You can top the same eSIM up from your account, without installing anything again.
05
Can I share it with a laptop?
Yes, hotspot is allowed on these plans. A laptop will use the allowance considerably faster than a phone.

What it will not do
It gives you no local phone number, so it cannot receive an SMS code from a service in Japan. Your own number keeps doing that.
