UK eSIM
Travel Data for London & More
Only for iPhone
Free · Designed for iPhone. Not verified for macOS.
iPhone
One eSIM for the whole UK, from London to Edinburgh. Plans from a day to a month or unlimited, data top-ups in the app, and no roaming bill.
Heading to the UK? Land with your phone already online instead of hunting for a SIM card at the airport. UK eSIM covers England, Scotland, Wales and Northern Ireland. Install it at home in two minutes and you are online the moment you land.
BUILT FOR THE UK
Your data runs on a national UK network, 4G/5G depending on the plan, and every plan shows its network before you pay. Your eSIM arrives in the app and by email moments after checkout.
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.
KEEP YOUR NUMBER AND WHATSAPP
UK eSIM is data only and runs beside your everyday SIM card, so your own number stays active. WhatsApp, calls, texts and bank codes keep working while UK eSIM carries your mobile internet.
HOW IT WORKS
1. Pick a plan for your trip.
2. Install in one tap, or scan the QR code, at home over WiFi.
3. Turn on data roaming for the UK eSIM line, which is what lets it connect.
4. Land, and you are online automatically.
PLANS FOR EVERY TRIP
Day passes for a short stay, weekly and monthly plans for a longer one, and unlimited when you would rather not count gigabytes. Unlimited includes a daily high speed allowance, then continues at reduced speed, as shown on the plan. Most plans can be topped up with more data in the app, and hotspot lets a laptop or a friend share your data.
BEYOND THE UK
Going on to Paris or Dublin? A Europe & UK plan covers the UK and all 27 EU countries on one eSIM, or 41 countries adding Switzerland, Turkey, Norway and the Balkans. The same app covers 200+ destinations worldwide.
BUY NOW, ACTIVATE LATER
Your eSIM stays ready to activate for at least 6 months, and a UK plan starts counting only when it first connects in the UK. Buy weeks ahead and install when you are ready.
HONEST PRICING
The price you see is the price you pay. No contract, no auto renewal, no roaming surcharge. Pay with Apple Pay or card, and track your remaining data in the app.
WELCOME DISCOUNT AND GIFT BALANCE
Your first order has a discount code waiting in the app. Every purchase adds gift balance to your wallet for your next eSIM. Invite a friend and you both earn.
SUPPORT BY EMAIL
Write to our team any time. Real people answer, no bots.
COMPATIBLE DEVICES
iPhone XS and newer, plus iPad Pro, Air and mini with cellular. The app can check yours before you buy.
