How to cancel your O2 contract?

If you're looking to cancel your contract with O2 in the UK, there are a few things you need to take into account. First and foremost, you need to make sure that you're actually within your cancellation period - otherwise you'll be liable for early termination fees. Once you're sure of that, the next step is to give O2 a call and let them know that you'd like to cancel. They'll likely try to retain you as a customer by offering various discounts and deals, but if you're firm in your decision then they'll eventually process the cancellation. In most cases, you'll just need to provide them with your account number and contact details - they'll take care of the rest. Just remember that once your contract is cancelled, you'll need to pay off any remaining balance on your account before you can completely close it down. With that in mind, it's always best to have a solid plan in place before you initiate any sort of contract termination.
