In this guide we will walk you through an O2 contract, what you can find on your bill and what happens if you want to leave. We will also look at payment options and your rights as an O2 customer.

What is in an O2 mobile contract?

Your contract spells out the relationship between you, as the customer and O2. A contract of this type is known as a Service Level Agreement (SLA). It lays out what each party should expect from the relationship. Let’s take a look at some of the contents of an O2 SLA.

O2 contacts fall into two main types plus a traditional PAYG option. SIM only contracts are designed for people who are happy with the phone they already have. SIM only contracts last 30 days, 12 months or 24 months. The other type is a device contract, where you are making a monthly payment for your new phone plus a payment for your airtime. Airtime is the name O2 has given to its data, calls and texts bundles.

Contract length

O2 offers numerous different contract durations. Contracts are available lasting anywhere from three months to 36 months with many options in between. The cost and duration of your contract is affected by factors such as which phone you want to buy, how much you want to pay up front, which airtime bundle you choose and how long you want to be tied in.

Your plan

Your contract will show you what is included in your plan. This will be the mobile device you are buying, The amount of data you get, how many minutes are included, plus offers and benefits bundled with your package, such as free subscription to a streaming service.

Modern mobile phone plans tend to focus on the amount of data they offer and O2’s plans offer anything from 1GB of data per month to unlimited data plans.

Your phone number, and other details such as any extras you have added are also shown in the contract.

Mobile device

When you sign up for a pay monthly plan which includes a mobile device, a significant part of your monthly payment is paying for the device you have purchased. If you already have a mobile device and go for a SIM only plan, then you are only paying for your data, calls and texts. You can also choose to buy your device outright in the first place, to get a cheaper, SIM only monthly bill.

Price changes

O2’s tariffs change each April in-line with inflation. So you can expect a yearly increase in the cost of your plan..

Cooling-off period

If you change your mind about signing-up with O2, you have 14 days to cancel from the time you signed the contract. After the 14 day cooling off period you will need to pay the remaining balance of the whole contract if you wish to leave early.

What is in an O2 mobile bill?

Your O2 bill lists the charges you have incurred over the previous month and the advance charges you need to pay. There is also other useful information. You can view your bill by logging into My O2 on its website, or on the My O2 app on your mobile device. Paper bills are available but you will need to pay an extra fee.

Paying your O2 mobile bill

In most cases you will pay your monthly bill by direct debit. You can also pay your bill using the My O2 app or on the O2 website with a credit or debit card. Alternatively you can pay over the phone.

Late payment will lead to extra charges, so if you are having trouble with your bill you should contact O2, which may help you avoid extra charges.

Cancelling your O2 mobile contract

If your contract has ended you can leave O2 without any issues arising. However if you wish to leave a contract early you will be charged a termination fee based on the time remaining on your contract.

Cancellation charges

If you cancel your plan within the first 14 days of your contract, there is no termination fee. After the 14 day period you are in for the long haul. If you decide to leave O2 while your contract is still running, you will need to pay off the entire remaining contract in full.
