Japan eSIM: Frequently Asked Questions

Does this Japan eSIM work on Android?

This SoftBank native eSIM is optimised for iPhone and is our recommendation for iPhone users. With a Pixel, Galaxy or other Android phone, we recommend KDDI native: high-speed unlimited, and it works on Android and iPhone. If you want to pick your own data and days, the KDDI／SoftBank dual-network eSIM is another option.

Which areas does the Japan eSIM cover?

All of Japan, including Okinawa. SoftBank is one of Japan’s major carriers, and cities such as Tokyo and Osaka as well as sightseeing areas across the country are covered. No plan change or setting adjustment is needed.

How much data do I need for a week in Japan?

We recommend a plan with comfortable headroom. Maps, navigation, translation, social media and messaging usually add up to more than expected, and having enough data makes travelling abroad more relaxed. Around 3GB a day suits most travellers; if you drive with navigation, stream video, upload lots of photos or share the connection, go straight for unlimited.

How are the days counted on this Japan eSIM?

Counting starts when you scan the QR code and activate. The first day runs until 23:59 (UTC+8 Time Zone) that same day, and the second day begins after 00:00. Activate after you arrive in Japan rather than before you leave, so you do not waste a day.

When should I install the eSIM?

Install on your departure day while your phone still has internet — airport Wi-Fi works, or your home network before you fly. An eSIM cannot be activated without a connection.

How long is the QR code valid?

The eSIM must be activated within 30 days of delivery or it expires, and that is the buyer’s responsibility. Ordering about a week before departure is ideal rather than months ahead.

Which devices are not supported?

iPads, tablets, customised devices, contract phones, carrier-locked phones, and jailbroken or rooted devices are not supported. Before ordering, dial *#06# — if an EID appears your handset supports eSIM. Also confirm the phone is not locked to a carrier.

How soon will I receive it after paying?

The QR code is sent automatically to your contact email within about 10 minutes of payment. If it does not arrive, check your spam folder or contact our LINE official account @peanutmo / WhatsApp +886-921-963-203 (10:00-17:00, UTC+8 Time Zone).
