Before you buy

The rules, limits and cautions for this plan. Read them before you buy: once it is installed or its validity has started, it cannot be refunded.

  • This plan can't be refunded once bought. The supplier marks the eSIM as in use as soon as it's issued. Before you buy, check that your phone supports eSIM and isn't carrier-locked.
  • You can install this eSIM once. If you delete it from your phone, it can't be restored or installed again.
  • The plan starts on the day you buy it, not the day you land. Days are counted by the calendar in Japan time (JST): the day you buy is Day 1, and the plan ends at 11:59 PM JST on the last day. Buy it on the day you travel to Japan and install it right away.
  • This plan cannot be topped up. If it runs out you buy a new plan and install it as another profile.
  • You can't check data use for this plan, on our site or the supplier's.
  • Keep Data Roaming turned off for this eSIM.
  • Hotspot works, but the supplier caps how much data you can share and hasn't published the limit.
  • Runs on KDDI/au only. Where KDDI/au is weak there is no second network to fall back on.
  • Data only: no phone number and no SMS. Keep your home SIM for OTP codes.
  • No data cap. Full speed for the whole plan.

FAQ

Can I install it before I fly?+

You can install early, but this plan starts counting at purchase, so buy it close to your travel date. You can install this eSIM only once, so do not delete it from your phone afterwards.

Can I share the connection over hotspot?+

Yes, but the supplier caps how much data you can share over hotspot and hasn't published the limit. Whatever your friends use comes out of your plan.

What if I run out of data before I fly home?+

This plan cannot be topped up. If you run out, buy another plan and install it as a second profile.
