Your United Kingdom eSIM, explained
Across the United Kingdom a Roamly eSIM connects to EE, Vodafone UK, O2, or Three UK, all with mature 5G in London, Manchester, Edinburgh, and most large towns. Coverage is excellent along the populated south and the rail corridors, but the Scottish Highlands, mid-Wales, and remote Cornish coast still have genuine notspots where you'll drop to patchy 2G or nothing — handy to know before a Skye road trip or a hike in Snowdonia.
Post-Brexit gotcha: the UK is no longer part of EU roaming, so a Europe-wide plan won't always include it — check that Britain is covered if you're hopping over from the continent. A nice local upside: in London you can tap straight onto the Tube, buses, and most rail with a contactless card or phone, no paper Oyster top-up needed, so you barely touch your data for transit.

United Kingdom eSIM — FAQ
How much does an eSIM for United Kingdom cost?
Plans for United Kingdom start from $2.99, with larger and unlimited options available. Every plan already has a 30% discount applied.
Which networks will I connect to in United Kingdom?
Your eSIM connects to leading local carriers in United Kingdom, using 5G where it's available, so you get data just like a local SIM.
When should I install my United Kingdom eSIM?
Install it as soon as you buy. Most plans only start counting once you arrive in United Kingdom and connect to a local network, so installing early is safe.
Will my phone work with an eSIM in United Kingdom?
If your phone is eSIM-compatible (most models from 2019 onward) and carrier-unlocked, it will work in United Kingdom.
Can I make calls with the eSIM in United Kingdom?
Our travel eSIMs are data-only, but you can call and message over the internet using apps like WhatsApp, FaceTime, or Telegram while connected in United Kingdom.
Does an EU roaming plan automatically include the UK?
Not always — since Brexit the UK sits outside EU roaming, so many Europe bundles exclude it. Confirm Britain is on the coverage list, or pick a UK-specific plan.
Do I need mobile data to ride the London Underground?
No. Just tap a contactless card or phone at the gates; daily fare capping is automatic. Data is only useful for live journey planning in TfL Go or Citymapper.
