Going to Japan? Don't land without internet, and don't spend your first hour hunting for a SIM card counter in a language you can't read. Japan eSIM does one country and does it properly. Your data runs on NTT docomo, au and SoftBank, the same networks locals use, with nationwide coverage from Tokyo to the smallest mountain town. Install at home in two minutes and you are online the moment the plane doors open. BUILT FOR JAPAN, NATIONWIDE COVERAGE 5G in the cities and coverage across the countryside, ski slopes and islands, on the networks Japan itself uses. The exact carrier and network type are shown on every plan before you pay, never after. Your eSIM arrives in the app and by email moments after checkout, and an eSIM you never use can be refunded. WHY AN eSIM BEATS POCKET WIFI No rental counter at Narita, Haneda or Kansai, and nothing to post back before you fly home. No deposit, no contract, no battery to charge nightly, no device to lose. Your phone is the device. WHAT IS AN eSIM? A digital SIM card already built into your phone. Nothing to insert, nothing to lose. Buy, install in a tap, connect. DUAL SIM: KEEP YOUR NUMBER, LINE AND WHATSAPP Japan eSIM is data only and runs as a second line beside your everyday SIM card, so your own number stays active. LINE, WhatsApp, iMessage, calls, texts and bank codes keep working as at home, while Japan eSIM carries your data. HOW IT WORKS 1. Pick a data plan for your trip. 2. Install your eSIM in one tap, or scan the QR code. Do this at home over WiFi. 3. Turn on data roaming for the Japan eSIM line. That is what lets it connect. 4. Land, and you are online automatically. PLANS FOR EVERY LENGTH OF TRIP Prepaid day passes for a short stay, weekly and monthly plans for a longer route through Tokyo, Osaka and Kyoto, and unlimited when you would rather not count gigabytes. Unlimited includes a daily high speed allowance, then continues at reduced speed, with the exact limit printed on the plan card. Most plans can be topped up in the app without installing a new eSIM. MOBILE HOTSPOT INCLUDED Tether a laptop, a tablet or your travel group, so one plan keeps several people online. BUY NOW, ACTIVATE LATER Your eSIM stays valid to activate for at least 6 months, and the plan only starts counting when it first connects in Japan. Buy weeks before you fly and install when you are ready. SUPPORT IN YOUR OWN LANGUAGE Message us on WhatsApp 24 hours a day, 7 days a week, or email us. Real people in your own language, no bots and no ticket numbers. The app is available in 23 languages. HONEST PRICING The price you see is the price you pay. No contract, no auto renewal, no roaming surcharge, no charge for the eSIM itself. Pay with Apple Pay or card, and track your remaining data and expiry date in real time. BALANCE BACK ON EVERY ORDER Every purchase adds gift balance to your wallet for your next eSIM. Invite a friend and you both earn. COMPATIBLE DEVICES iPhone XS and newer, plus iPad Pro, Air and Mini with cellular. The app checks yours on the Support screen. AFTER JAPAN Japan is what we do, and the same app covers 200+ countries and regions, including Korea, Taiwan and Thailand, so one account carries the rest of the trip. QUESTIONS Do I keep my own number? Yes, Japan eSIM sits next to your normal SIM card. Do I need WiFi to install it? Yes. Install at home before you travel. Which network will I be on? NTT docomo, au or SoftBank, shown on the plan before you buy. When does my plan start? When the eSIM first connects in Japan, not when you buy it. Can I get a refund? Yes, an eSIM you never activated can be refunded. Is there a phone number? No. It is data only, so use LINE, WhatsApp or FaceTime for calls. Does my phone need to be unlocked? Yes. It must be carrier unlocked and eSIM capable. Support: support@redsim.app Privacy Policy: https://redsim.app/privacy-policy?app=japan Terms of Service: https://redsim.app/terms-of-service?app=japan
