Prepaid SIM Cards for Everyday Use

A UK prepaid SIM card gives you a mobile number and network access without a contract. You pay for what you use, so there are no monthly commitments and no credit check. That is why the best SIM cards in UK searches often lead to simple pay as you go options: they are easy to set up, easy to top up and easy to switch.

UK Prepaid SIM Card: How It Works

Order your SIM, insert it into an unlocked phone and activate it on the network's website or app. Then add credit or choose a data bundle and you are connected. The EE pay as you go 4G/5G SIM is a good example: one trio card that covers standard, micro and nano slots.

4G SIM Cards and 5G SIM Card Options

A 4G SIM card handles streaming, maps, video calls and everyday browsing with ease. A 5G SIM card adds faster speeds where 5G coverage is available, but you also need a 5G-compatible phone. Our EE SIM supports both 4G and 5G, so it works today and is ready if you upgrade to a 5G handset later.

Data SIMs Pay As You Go

A data SIM pay as you go lets you buy mobile data when you need it instead of paying a monthly fee. After you activate your SIM, choose a data bundle from your network and top up when it runs out. This suits light users, second phones, tablets and anyone who prefers to stay in control of their spending.

Preloaded Data SIM: What to Know

A preloaded data SIM comes with a set data allowance already on it, sometimes valid for a long period such as 12 months, so you do not need to top up each month. The SIM cards on this page are pay as you go, which means you decide how much data to add and when.

SIM Card With Number

Every SIM card comes with its own UK mobile number once it is activated. If you would like something easier to remember, see our Lebara VIP gold number SIM, which gives you a memorable number for personal or business use.

London SIM Card for Residents and Visitors

A London SIM card is simply a UK SIM that works in London and across the rest of the UK. If you are moving to the city, visiting, or need a spare number, a prepaid SIM gives you a UK number and mobile data for maps, transport apps and messaging. Both EE and Lebara cover London, but check the network coverage map for your area.
