Best O2 Deals in the UK

The best O2 deals are handset deals which include a phone and a monthly allowance. All O2 plans include unlimited texts, minutes and data.

You’ll pay a fixed monthly price over 36 months for your handset deal but you can choose to pay your phone off sooner by reducing the length of your contract to anywhere between 3 and 36 months. The monthly cost of your handset deal will vary depending on the phone and data allowance you opt for. 

O2 unlimited 5G monthly plans are top picks amongst the provider, and vary in price depending on the mobile phone device. Keep in mind that you’ll have to pay a fee upfront which is not included in the monthly cost. This is usually between £10 and £90, depending on the phone you choose. You can also pay more upfront to keep your monthly phone payments down.

If you can’t find the right monthly plan for you, O2 will let you customise your own. You can choose whether to add more or less data to a pre-built plan and how long you want the contract to last so that it suits your requirements and budget. If you decide to cancel your contract, there’s a 30-day notice period, and you may be charged an early termination fee if you decide to end it early. 

More O2 Monthly Plans

There are many cheaper, pre-built O2 monthly plans which offer less data allowance and older phone models. These plans are still among the best O2 mobile deals and offer anywhere between 1GB of data and 150GB of data a month.

O2 SIM Only Deals

O2 sim only deals offer a variable data allowance, unlimited texts and unlimited minutes. The price of your sim only deal will vary based on the contract length and the data allowance you choose. You can get a contract for 12 months, 24 months, or a 30-day rolling contract. The cost of each plan and the benefits on offer are:

A 30-day contract is a rolling contract that will carry on unless cancelled, in which case there’s a 30 day notice period. All prices are correct at the time of writing but are only intended as a guide - they may change down the line.

O2 sim-only deals don’t include a handset so you’ll need to have your personal unlocked phone. To get your O2 sim card, visit the O2 website and answer a few simple questions. You’ll be asked:

  • Which phone do you have?
  • Does your mobile device support 5G?
  • Do you want to add a Spend Cap?

Your sim will be with you within 2 working days and you’ll need to activate it from home following the instructions it comes with.

You can choose to customise your handset deal with O2, which means you decide the length of your contract and how much data allowance you’ll get every month.  You can also change your data plan every month if you want to.

4G and 5G Network Coverage

O2 has gone live with 5G in most large towns and cities in the UK and in many smaller towns, too. O2 also offers 5G in most key business and transport areas. To get 5G, you’ll need a mobile device that supports it, which are typically the newer models. Use the coverage checker to see if 5G is available in your area. 

O2 offers 4G coverage too but it costs the same as 5G, so opt for 5G if your device supports it in order to enjoy faster data speeds where available.

5G network average speeds:

  • Download speed of 155 Mbps.
