Does a UK eSIM work after Brexit for EU visitors?

A UK plan covers England, Scotland, Wales, and Northern Ireland on the product list. It does not replace an EU/Schengen plan—if you also visit France or Spain, you need multi-country or separate plans.

United Kingdom eSIM vs Europe 30 regional plan?

London-only trip: a UK plan is enough. UK plus Paris or Amsterdam: check whether your Europe 30/40 bundle lists the United Kingdom, or buy UK + regional.

Will it work on the London Underground?

Yes in stations and tunnels where your network has coverage—same as any mobile data. Download offline Tube maps before you go.

Is UK eSIM cheaper than EU roaming?

For travellers from outside Europe, prepaid UK data is often clearer than paying home roaming. EU residents should compare with their home bundle.

Unlocked phone required?

Yes—eSIM-capable and not locked to a single carrier.

United Kingdom eSIM: London, Edinburgh & Multi-City Trips

After Brexit, the UK is outside the EU roaming zone for many European carriers—so a prepaid UK eSIM is often the simplest way to stay online in London, Edinburgh, or on a train to Manchester. If your trip continues to Paris or Amsterdam, compare a UK-only plan with our Europe 30 regional bundle.
