Practical guide
Activate your eSIM before you fly if the provider supports it — many plans let you install the profile ahead of time and simply turn on data roaming after landing. If you’re bringing a pocket Wi-Fi device instead, most airport counters offer both pickup and return, so plan a few extra minutes at arrival and departure.
FAQ
Common questions
Do I need to unlock my phone to use a Japan eSIM?
Most modern phones support eSIM without unlocking, but check with your home carrier that your device is eSIM-compatible and carrier-unlocked before you travel.
Is an eSIM better than pocket Wi-Fi?
An eSIM is usually simpler for solo travelers with compatible phones. Pocket Wi-Fi can be a better fit for groups sharing one connection or travelers with older devices.
Can I keep my regular number active alongside a travel eSIM?
Yes — most eSIM plans run alongside your existing SIM, so you can keep receiving calls and texts on your home number while using the eSIM for data.
