No Premium tier is selectable on the Japan product. Review speeds, hotspot conditions, validity and current price on the live Japan plan page. More data cannot extend coverage offshore.

Arrival and main-island travel

Save the airport or arrival point shown on your booking, lodging address and transfer instructions before leaving Wi-Fi. Download a map and confirm transport options for your actual route. The eSIM does not include transport or lodging, and reception can vary indoors.

Coastal days

Keep accommodation and meeting points offline. Check beach access, weather and activity conditions with local providers. Service depends on the local network and exact location; no particular stretch of coast is guaranteed.

Optional outer-island trips

Confirm each island in your itinerary against your selected plan's destination and coverage information. Save ferry tickets, operator contacts and return times offline. Do not assume mobile service at sea or on an outer island merely because Okinawa is named in the product.

Install and troubleshoot

1. Choose a Japan plan and validity, complete checkout and open the emailed QR code on another screen.
2. Connect an unlocked eSIM-compatible phone to Wi-Fi. Add an eSIM in iPhone Cellular/Mobile Data settings or Android SIM manager/Network settings, then scan the code. Label it AloOui and follow the delivery email; do not delete the installed eSIM.
3. On arrival, select AloOui for mobile data and follow the plan's activation instructions. If data fails where signal exists, check validity and instructed roaming, toggle airplane mode and follow any APN guidance. Visit the AloOui Help Center for assistance.
