  • Tariff Information

    O2 offer a range of SIM only deals, which are referred to as ‘O2 Simplicity’ contracts. These contracts are ideal for those who already have a phone they’re happy with, as they offer the same benefits as a standard monthly contract but at a cheaper price since the cost of a handset is not factored into monthly charges.O2 Simplicity contracts also offer flexibility, as they are available as either 12 month fixed duration contracts or monthly rolling contracts.

    A great feature of SIM only contracts from O2 is that every Pay Monthly Simplicity contract includes unlimited any network text messages. Beyond this, all SIM Only contracts also include a monthly allowance of inclusive minutes and customers can add either a low, medium or high data allowance. 12 month contracts generally have cheaper monthly costs than 1 month equivalents, as an incentive for the longer commitment.

    O2 offer a range of Bolt Ons to customise tariffs and add additional monthly services.
