Japan eSIM questions
- Is there an unlimited data eSIM for Japan?
- Not at the moment: every Japan plan has a data allowance. The nearest thing is a day pass, with a fresh allowance every day for as many days as you choose. When a day's allowance is used up, data keeps working at up to 256 kbps to 1 Mbps until the next day starts.
- Do I get a Japan phone number?
- No. These eSIMs are data only, so they come without a local number and do not carry calls or ordinary texts. WhatsApp, iMessage and FaceTime keep working over data with your usual number, and your normal SIM can stay on for calls and texts from your home provider, at their rates.
- Can I use it as a hotspot?
- Yes. You can share the eSIM's data with a laptop, tablet or another phone with your phone's personal hotspot. Shared data comes out of the same allowance, so pick a bigger plan if you will work from a laptop.
- How do I avoid roaming charges in Japan?
- Use the eSIM for mobile data and turn off data roaming on your home SIM, so your phone cannot fall back on your home provider. Turn data roaming on for the eSIM line itself: that is how a travel eSIM connects abroad, and it costs nothing extra. Calls and texts on your home SIM may still be charged at your provider's roaming rates.
- Which is the best eSIM for Japan?
- There is no one best plan for everyone, so judge any Japan eSIM on a few things: which networks it uses, whether it offers 5G and your phone supports it, whether the data and days fit your trip, whether it can be topped up without a new eSIM, and the price per GB. The "Which plan for your trip?" table on this page picks the cheapest plan for three common trips from today's prices.
