While pay-as-you-go SIMs are available at Heathrow and high street shops, they require UK address registration since 2022. Free WiFi on the London Underground covers most Zone 1-2 stations but not the tunnels between them. An eSIM gives you instant connectivity from landing.
EE has the widest 4G/5G footprint across England, Scotland, and Wales. Three offers strong 5G in London, Manchester, and Birmingham. Coverage can be patchy in the Scottish Highlands, rural Wales, and parts of Cornwall — download offline maps for hiking areas.
Citymapper is the best app for London transport (Tube, buses, Overground). Google Maps handles the rest of the UK well. Budget 1-2 GB per day for active navigation, or less if you're mainly in cities with WiFi access at cafes and hotels.
The UK uses three-pin plugs (Type G) — bring an adapter. Train WiFi on services like Avanti West Coast and GWR is notoriously unreliable, making mobile data the better option for working on the move.
