Best O2 SIM Only Deals

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.

O2 SIM only customers have two main options for accessing the internet through O2’s mobile network:

• Add a monthly mobile data allowance. SIM only customers can choose a ´Low´, ´Medium´, or ´High´ data allowance. The Low option adds 100 MB of data, the Medium option adds 250 MB to 750 MB and the High option adds either 1 GB or 2 GB of monthly data. The size of Medium and High data allowances is dependent on the contract chosen.
• Customers who do not have a data Bolt On can access the internet with O2’s Web Daily service.
