More About O2

O2 Plans

No two customers are the same which is why O2 plans are tailored to suit different lifestyles.

Choose from O2 sim only tariffs, pay-as-you-go deals or plans that deliver mobile and broadband combos at great prices. Talk for longer as well with O2 discount codes from online portals.

O2 Online Top Up

If you've chosen an O2 pay-as-you-go tariff, topping it up is easy with several payment options. Visit an O2 shop, make a phone call or do an O2 online top up.

Set up an auto top-up account to ensure you never run out of phone credit at a vital moment or top up for less by browsing for O2 top-up vouchers and O2 promo codes.

O2 Cancel Contract

Sometimes your needs change which is why O2 makes it easy to cancel your O2 contract. O2 Refresh customers can pay off and cancel their contracts at any time while others can leave at the end of a contract period.

You can even take your O2 phone number to a new provider should you wish. Please note: you might be charged if you cancel before a contract period ends.
