Japan eSIM: Frequently Asked Questions

Does this Japan eSIM work on Android?

Most Android handsets cannot use this product — it is built for iPhone. If you carry a Pixel, Galaxy or any other Android device, choose the Japan dual-network eSIM (KDDI and SoftBank) instead, which installs normally on Android. Google Pixel phones are not supported by this product.

Does the Japan eSIM work in Okinawa and Hokkaido?

Yes. SoftBank is one of Japan’s major carriers and its coverage includes Okinawa and the Hokkaido ski fields as well as central Tokyo and Osaka. No plan change or setting adjustment is needed.

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

We would not recommend the smallest plan — leaving headroom is the safer choice. Maps, navigation, translation, social media and messaging add up to more than most people expect, and running out of data abroad is the worst moment to find that out. For most travellers around 3GB a day is a more comfortable starting point. Where this destination offers a total-data plan (10GB or 20GB, for example), that is usually our first recommendation: a heavy day will not leave you stuck, and the allowance spreads across the whole trip. If you stream video, upload a lot of photos, or need to share the connection with another device, an unlimited plan is the simplest answer.

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).
