O2 simplicity (sim only)

What is simplicity?

Simplicity is just a sim. It means you can stick with your current phone and pick a sim only simplicity tariff, which gives our 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, we've got three packages to choose from, depending on how much you use the internet on your phone.

What's the difference between Pay Monthly simplicity and Pay & Go simplicity?

Simplicity is available on Pay & Go, 1 month and 12 month Pay Monthly so you can choose the payment option that suits you. Here's something to help you pick the right mix of minutes and texts for 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.
