Flying into Heathrow, Manchester or Edinburgh? Scan the QR code before you set off and your phone finds a British network by itself — no airport kiosk, no hunting for a shop that sells tourist SIMs.
The UK sits inside a 33-country European bundle, so the eSIM you buy for London keeps working on the Eurostar to Paris, a stopover in Amsterdam or a week in Spain later in the year. Install it at home, confirm it works, and it picks up wherever you land next.
Every plan below covers United Kingdom. Choose the number of days you're away — the price is fixed, you pay once, and nothing renews afterwards.
You can be in a capital city in the morning and empty hills by mid-afternoon. The same eSIM comes with you.
Most of the big museums are still free, but the exhibitions that sell out are booked online and the Tube runs on contactless. Add a same-day theatre ticket and a table you found twenty minutes ago, and a connection earns its keep.
The Old Town on foot, then the road north through Glencoe to Skye. Signal follows the main roads and thins out in the glens, so download the route before you leave the city.
Yr Wyddfa, the Llŷn Peninsula and a coast path that runs the whole way round the country. Car parks at the popular trailheads book up online before dawn in summer.
Sixteen lakes, a lot of weather and fell forecasts that change hour to hour. Worth checking before you commit to a ridge, and worth having a map that works when the cloud comes down.
Beaches, coast path and more seafood than the roads can comfortably carry in August. Tide times decide half of it — when you can walk to St Michael's Mount, when the cove disappears.
The Titanic Quarter, black taxi tours and then the Antrim coast road out to the Giant's Causeway. Timed tickets at the Causeway visitor centre keep the crowds moving.
Live Tube and rail routing, National Rail updates when something inevitably goes wrong, and a map that keeps working on a moor with no signposts.
Museum exhibitions, castle slots and restaurant tables increasingly sell out online before you reach the door. Being able to book from the queue is the whole point.
WhatsApp, FaceTime and Signal all run over data, so calls home cost nothing beyond the plan you've already paid for.
Let a fortnight of pictures sync as you travel rather than praying your phone survives the trip home. This is the one that eats data, so save it for the evening.
A cancelled train, a closed road or a hotel that can't find your booking. All of it is easier to fix with a working connection than without one.
The whole thing takes about as long as printing a boarding pass, and it's far easier done on your own Wi-Fi than in an airport queue.
Pick the plan that matches how long you're in the UK. If you're carrying on into Europe, the same eSIM already covers you.
It arrives by email as soon as you pay. Open your phone's mobile settings, add an eSIM, scan — done in under a minute, over Wi-Fi at home.
Your plan starts when the eSIM first finds a network in the UK, not when you bought it. Turn roaming off on your UK line and you're set.
The eSIM on this page covers these too — one plan, every country on the list.
Sort your connection tonight and forget about it. One scan now, and Britain is just somewhere your phone already works.
