O2 Sim Only

By placing customers at the heart of everything, O2 have created, and continue to create memorable experiences where everyone feels valued, recognised and rewarded.

Simplicity is just a sim. It means you can stick with your current phone and pick a sim only simplicity tariff, which gives the best value. Plus you can pick as much or as little data as you need, no matter which simplicity tariff you choose. Starting from £3 a month, there are three packages to choose from, depending on how much you use the internet on your phone.

Simplicity is available on Pay & Go, 1 month and 12 month Pay Monthly so you can choose the payment option that suits you. For Pay & Go you pay with your top up, and for the Pay monthly options you pay by direct debit, along with your bill.

Pay Monthly simplicity tariffs mean you don't have to worry about keeping your phone topped up, you can pay by direct debit for the 30 day or 12 month tariffs. And you get O2 Pay Monthly rewards. Depending on how much you spend you can get early upgrades (if you fancy a new phone) and a discount on home phone and broadband, which then count towards your monthly spend and can help you to move up the tiers to get better rewards.

Pay & Go simplicity gives you Top-up Surprises every time you top up and O2 Pay & Go rewards. You'll be rewarded every 3 months with up to 10% of your top-ups back to spend on credit, phones, accessories, vouchers or gig tickets.
