Is a 7-day eSIM cheaper than buying a local SIM in Japan?
For short trips, eSIMs are often cheaper and more convenient than local SIM cards — no need to find a store at the airport, no physical card to swap, and you can compare prices online. Airport SIM counters typically charge 20-50% more than online eSIM prices.
Is it better to buy an eSIM or a physical SIM for Japan?
An eSIM needs no card swap, can be installed before departure, activates right after landing, and supports dual SIM (keeping your home number). A physical SIM suits cases needing a local phone number or a device without eSIM support. Compare eSIM prices here first — they're usually cheaper than airport counters.
How do I activate a Japan eSIM after landing?
Install it before departure over Wi-Fi. After landing, enable data roaming to auto-activate; if there's still no service after 1-2 minutes, manually select the local operator in settings. Checking device compatibility before departure reduces the risk of activation failure.
