Going abroad? Don't land without internet, and don't pay your carrier's roaming bill. RedSim puts a local eSIM on your phone in Europe, Japan and 200+ countries: a prepaid data plan you install at home in two minutes, so you are online the moment you land. No SIM card to buy at the airport, no contract. WHY TRAVELLERS TRUST REDSIM Your data runs on real local networks, and the exact carrier and network type are shown on every plan before you pay. Your eSIM arrives in the app and by email seconds after checkout. Our team answers on WhatsApp 24 hours a day in your own language, and an eSIM you never use can be refunded. BALANCE BACK ON EVERY ORDER Every purchase adds 25% gift balance to your wallet, ready to spend on your next eSIM. Invite a friend and you both earn. 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 AND WHATSAPP RedSim is data only and runs as a second line beside your everyday SIM card, so your own number stays active. WhatsApp, iMessage, calls, texts and bank codes keep working as they do at home, while RedSim carries your data. HOW IT WORKS 1. Pick a destination and a plan. 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 RedSim line. That is what lets it connect. 4. Land, and you are online automatically. PLANS FOR EVERY TRIP Prepaid day passes for a weekend away, weekly and monthly plans for longer trips, and unlimited when you would rather not count gigabytes. Choose a single country, a region like Europe, or a global plan that covers the whole route. Unlimited includes a daily high speed allowance, then continues at reduced speed, with the limit shown on the plan before you buy. 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 6 months, and the plan only starts counting when it first connects at your destination. 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 47 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. COMPATIBLE DEVICES iPhone XS and newer, plus iPad Pro, Air and Mini with cellular. The app checks yours on the Support screen. WHERE YOU CAN USE IT Europe in one eSIM, with Switzerland, Italy, France, Germany, Spain and the UK covered, or a single country when you only need one. Japan, Thailand, Dubai, Turkiye, Canada, the USA and 200+ countries and regions in total. QUESTIONS Do I keep my own number? Yes, RedSim 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? The exact carrier is shown on every plan before you buy. When does my plan start? When the eSIM first connects at your destination, 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 WhatsApp, iMessage or FaceTime for calls. Does my phone need to be unlocked? Yes. Your phone must be carrier unlocked and eSIM capable.
