Where to Buy a UK Mobile SIM Card

You can buy Pay As You Go SIM cards (we recommend this rather than a contract or plan, which may charge you more) from physical mobile phone shops in London, such as Three, O2, EE, and Vodafone.

We do not recommend buying SIM cards from supermarkets, as they may not work reliably.

Alternatively, you can purchase a SIM card in your home country before travelling for extra convenience.
