How a Japan eSIM works

No shop, no plastic SIM and no passport copy — the whole process takes about five minutes.

Choose your plan

Pick the data and validity that fit your trip. Check your phone supports eSIM.

Pay securely

Verify your email and pay with PayPal. Prices are final, in USD.

Get your QR code

Your eSIM QR code arrives by email in minutes and is saved on the My eSIM page.

Land & connect

Scan the QR before you fly, then turn on the eSIM and data roaming when you arrive.

Tip: install the eSIM while you still have Wi-Fi, and turn on Data Roaming for the eSIM line after landing in Japan. Roaming is included in the price — there are no extra charges.

Coverage & networks

Stay connected across Japan

Japan’s rail network is famously punctual, but it is also famously complex. Live train routes, platform numbers, restaurant reservations and menu translation all need data — and free Wi-Fi is patchy once you leave your hotel. A Japan eSIM connects you to NTT docomo, KDDI (au) or SoftBank as soon as you land at Narita, Haneda or Kansai, so you can ride the Shinkansen, find that ramen shop in Shinjuku and share the cherry blossoms without roaming charges.

  • Osaka
  • Kyoto
  • Hokkaido (Sapporo)
  • Okinawa
  • Hiroshima
  • Nara
  • Fukuoka
  • Nagoya
  • Mt Fuji & Hakone

Coverage follows the local partner networks: excellent in cities, towns and along main travel routes; remote mountains, jungle and open sea can have weak or no signal, as with any local SIM.

Why Japan eSIM

Simple, safe and affordable

Why are we affordable?

Unlike airport kiosks or travel agencies, everything is automated: your eSIM QR code is emailed the moment you pay, and there are no shops, rental devices or airport counters to pay for. The price you see is the full price, paid once.

Why is it safe?

We only sell data-only travel eSIMs that need no personal registration or ID copies. Payment runs through PayPal, so we never see your card details.

Run out of data?

Plans marked Top-up can be refilled from the My eSIM page at any time. Each top-up adds data (and validity) to the eSIM you already installed — no new QR code needed.

Is it fast?

Each eSIM runs on the country’s leading carriers at the 4G/5G speeds listed on each plan. 24-hour passes slow to a reduced speed once the daily allowance is used.

FAQ

Japan eSIM questions, answered

Which networks does the Japan eSIM use?

Japan eSIM plans connect to NTT docomo, KDDI (au) and SoftBank — Japan’s major nationwide networks — and some plans also use Rakuten Mobile. Coverage includes Tokyo, Osaka, Kyoto, Hokkaido, Okinawa and the main rail corridors.

Is an eSIM better than pocket Wi-Fi in Japan?

For most travelers, yes. An eSIM costs less than renting a pocket Wi-Fi router, there is no device to collect at the airport or return by post, and it never runs out of battery. Pocket Wi-Fi can still suit large groups sharing one connection.

Does the eSIM work on the Shinkansen and in the subway?

Japanese carriers cover major train lines, stations and city subways, so you can keep navigating on the move. Short gaps can still occur in long mountain tunnels.

What is a Japan eSIM and how does it work?

A Japan eSIM is a digital SIM profile that adds a prepaid mobile data plan to your phone without a plastic SIM card. You buy a plan online, receive a QR code by email, scan it in your phone settings, and your phone connects to NTT docomo, KDDI (au) and SoftBank in Japan. Your regular SIM stays in the phone.

Is my phone compatible with eSIM?

Most phones from 2019 onwards support eSIM, including iPhone XS/XR and newer, Samsung Galaxy S20 and newer (plus Z Fold/Z Flip), and Google Pixel 3 and newer. Your phone must also be carrier-unlocked. Quick check: dial *#06# — if an EID number is shown, your phone supports eSIM.

When should I install the eSIM, and when does my plan start?

Install it at home or at the airport while you have Wi-Fi — installation needs an internet connection. The validity period starts when the eSIM first connects to a supported network in Japan, not when you install it, so installing a few days early does not waste any days.

Do I need to turn on data roaming?

Yes. Switch on Data Roaming for the eSIM line (Settings › Cellular/Mobile › your eSIM). A travel eSIM connects to local Japan networks as a visiting line, so the phone needs roaming on for it. It costs nothing extra: the data comes from your prepaid plan. Keep data roaming off on your home SIM, and your home carrier has nothing to charge you for.

Does the eSIM include a phone number, calls or SMS?

No — it is a data-only eSIM. Use WhatsApp, LINE, FaceTime, Messenger or other apps for calls and messages. Your home SIM can stay active alongside it for SMS verification codes.

Can I top up if I run out of data?

Yes, on plans marked Top-up. Open the My eSIM page, log in with your email and add more data to the same eSIM — no need to install a new QR code.

What if the eSIM does not work or I change my plans?

Most connection issues are solved by turning on data roaming for the eSIM line and restarting the phone. If it still does not connect, contact support with your order email — we reply within 24 hours, and if a problem on our side cannot be fixed we replace the eSIM or refund it in full. A change of plans is not a reason for a refund: once the QR code is emailed, the eSIM is issued to you and cannot be cancelled, so please check your dates and your phone before you buy.
