🇬🇧 About eSIMs in United Kingdom
The UK has excellent 4G and expanding 5G coverage across all four nations. Available networks vary by plan; check your selected plan for its included networks. You get strong signal in London (yes, on most of the Tube now that TfL has rolled out 4G in tunnels), Edinburgh, the Cotswolds, Snowdonia, and the Scottish Highlands including the North Coast 500.
Data needs are moderate: TfL Journey Planner, Citymapper, Google Maps and WhatsApp for pubs and Airbnb hosts. 8–10 GB covers a week comfortably; two-week travelers who also visit Scotland or Wales usually want 15 GB.
The UK is one of the few places where a physical airport SIM is not a disaster — EE and Three both sell prepaid at Heathrow — but you will pay 2–3× more and burn 30 minutes queueing. An eSIM avoids the airport SIM queue. Check when and where your selected plan must be installed.
