How a RoamFinch plan works
China mainland & Japan & South Korea lists 3 countries. A stop is included only when that country is on the package.
Confirm eSIM support and that the phone is unlocked. Those are two different questions. Open the destination and read the countries, data allowance, and validity. The price shown is the supplier's suggested retail price. A successful payment places one plan. The QR code or activation string arrives after the supplier accepts the order. Do not delete the eSIM until the trip is over.
