UK eSIM — common questions

What travelers ask before flying to the United Kingdom.

How much does a UK eSIM cost?
DataSIM UK plans are all valid for 30 days: 3 GB for $5.50, 5 GB for $8.50, 10 GB for $15, 20 GB for $26.50, 50 GB for $58.50, and 100 GB for $114.50 — as low as $1.15 per GB. No contracts or hidden fees, and you can top up anytime in the app.
Does the eSIM work in England, Scotland, Wales, and Northern Ireland?
Yes — one eSIM covers the entire United Kingdom: England, Scotland, Wales, and Northern Ireland. You won't need a separate plan when traveling between London, Edinburgh, Cardiff, or Belfast.
Will the eSIM work for an EU trip starting or ending in London?
The UK plan covers only the UK — since Brexit, the UK is no longer part of the EU "roam like at home" zone, so a UK plan doesn't extend to the EU and an EU plan doesn't extend to the UK. For trips covering both, you can either buy both plans, or check the Europe regional plan in the DataSIM app (it includes the UK in many packages).
Does it work on the London Underground and trains?
Yes on overground rail and increasingly on the Tube — 4G/5G is now available on Elizabeth Line platforms and progressively rolling out across the rest of the London Underground. Coverage is strong on most National Rail routes between major cities.
Will WhatsApp and Google Maps work in the UK?
Yes — WhatsApp messaging and calls, Google Maps, Instagram, and your usual apps all work normally on your DataSIM eSIM in the UK, and you keep your existing number.
Does it work in the Scottish Highlands or rural Wales?
Coverage is strong in cities, market towns, and along major roads. As anywhere, very remote areas — deep Highlands, isolated Welsh valleys, Hebrides islands — can have weak signal on any carrier. This is a UK-wide cellular limit, not specific to eSIMs.
Can I use my eSIM as a hotspot in the UK?
Yes, hotspot and tethering are supported on all DataSIM plans, so you can share your connection with a laptop or travel companions.
Does my phone support eSIM?
Most phones from 2019 onward do — including iPhone XS and later, Google Pixel 3 and later, and recent Samsung Galaxy models. Your phone must be carrier-unlocked.
When should I install my UK eSIM?
Install it before you travel, while you're on Wi-Fi. The plan only starts when the eSIM connects to a network in the UK, so installing early costs nothing.
What happens when my data runs out?
Top up instantly in the DataSIM app — no need to install a new eSIM.
