Please ensure that your device supports eSIM in advance.
SIM Lock Removal
eSIM is available for SIM-free devices. If your device is locked, please unlock it first. Check your carrier’s website for unlocking instructions.
Day Calculation
You can purchase and install the eSIM now, but it will only activate upon your arrival in Japan. The plan’s duration is based on Japanese Standard Time (JST). A “day” is defined as a calendar day from 00:00 to 23:59 JST. For example, if you activate the eSIM at 23:00 JST, the first day will end at 23:59 JST, regardless of the actual usage time. Please note that late activations will result in shorter usage time for the first day.
