3. Where to Buy a Prepaid SIM Card?

• At the Airport: Heathrow and Gatwick have kiosks selling prepaid SIM cards. While convenient, these are often more expensive.
• Official Retail Stores: Visit Vodafone, EE, or O2 stores where staff can assist with setup.
• Convenience Stores: Supermarkets like Tesco and Sainsbury’s sell prepaid SIM cards, but activation assistance may be limited.

Buying a SIM card at the airport may not be the most efficient option, as you will likely need to stay connected after leaving the airport WiFi. Getting to your hotel without a UK SIM card may be difficult. See why tourists opt for eSIMS. The best option is to buy an eSIM online before arrival. Check all of our eSIM options.
