What to know before you land
Brexit didn't change the eSIM experience for visitors, but EU SIMs no longer roam free in the UK — a dedicated UK plan saves you from surprise GBP roaming charges. Install before you fly, activate when you land at Heathrow or Edinburgh.
Best for: Tourists exploring London, Edinburgh, and the Scottish Highlands; business travellers shuttling between offices in London and Manchester; weekend break travellers from continental Europe.
Local tip: London Underground stations have Wi-Fi on the platforms, but no cell service in tunnels between stations. Download offline Maps before the Tube.
