Mobile data in Britain, from London to the Highlands
Since Brexit the EU roaming rules no longer cover the United Kingdom, so data use on a plan from an EU or EEA country is priced under your operator's own terms. Check the position before you travel. If your data allowance is small or you want your bill to stay as it is, an eSIM is a useful addition.
The plan uses the EE and 3 networks. In London, Manchester and other large cities coverage is good. In the Scottish Highlands, the islands and the hills of Wales and northern England the connection can weaken, so download maps for offline use before a hike or a long drive.
Getting around London works well without paper tickets: you pay for public transport by card or phone, and Citymapper or Google Maps show the route. Uber and Bolt handle rides and train tickets are in apps. All of that needs working data.
You can buy a local SIM at a shop or from a machine, but then the card has to be swapped and your number changes. With an eSIM your own SIM stays alongside, and WhatsApp calls home run over data.
