Japan eSIM FAQ

Does the Japan eSIM include calls or SMS?

No. These are data plans, and none of them include call minutes or SMS. Calls and messages go through apps such as WhatsApp or LINE.

Which network does the Japan eSIM use?

It uses the SoftBank and KDDI networks, both on 5G. We checked the network list on 24 Oct 2026.

How fast do I get the QR code?

By email, right after you pay. Most orders arrive in under a minute.

Will my home number stay active?

Yes. Your physical SIM stays active for calls and bank OTP SMS in dual-SIM mode.

What if I run out of data?

Buy a new eSIM on TravelyData. The plans run from 500 MB to unlimited data.

When should I install it?

On Wi-Fi before your flight. Then turn on Data Roaming for the eSIM when you arrive.

How do I check if my phone supports eSIM?

Find your model and check that it is not locked to a carrier on our list of eSIM-compatible devices.

Can I use Suica and train apps with this eSIM?

Apps that use mobile data work on this eSIM. For IC cards, the Shinkansen and local rules, see our Japan transport and etiquette guide.

What is your refund policy for the Japan eSIM?

You get a 100% refund if your phone does not support eSIM or is locked to a carrier, the eSIM has not been installed or activated, and you claim within 14 days of purchase. You also get a full refund if your eSIM is not delivered. If a technical error on our side stops the eSIM from activating, or the local network is down or the signal is too poor to use it, and our support team cannot fix it, we will refund it in full (for a technical error on our side, we may replace the eSIM instead). We do not give refunds for a change of mind, or once the eSIM has been installed or activated (except for a technical error or a local network problem). Full details: Cancellation & Refund Policy.
