Getting a local SIM in United Kingdom
🏪Where to buy
Airport kiosks at London Heathrow (LHR), Gatwick (LGW) and Manchester (MAN): Three and EE have arrival hall counters. In the city: every WHSmith newsagent and most Tesco, Sainsbury's and ASDA supermarkets sell prepaid SIMs. Three, EE, O2 and Vodafone have stores on most high streets. Budget operators (Giffgaff, SMARTY, Sky Mobile) are online-only but SIMs can be ordered to your hotel or picked up at a local convenience store after arrival.
📄Documents needed
No ID required to purchase a prepaid SIM in the UK — one of the few European countries where you can buy without showing any document. Giffgaff and SMARTY can be ordered online and activate via app with no in-store visit needed.
