In this comprehensive guide, we’ll explain everything you need to know about O2, including its benefits and drawbacks, tariffs, and SIM-only deals.

Why choose O2?

O2, the UK’s oldest mobile network, offers many benefits to its customers. With its wide range of tariffs, including flexible phone contracts and SIM-only plans, it caters to a variety of needs.

A major reason to choose the provider is its comprehensive UK coverage, which makes it accessible for almost everyone. Its network supports 4G technology, and its 5G coverage is growing.O2’s extensive range of rewards is also appealing and helps it stand out from competitors.

O2 coverage

O2’s 3G, 4G, and 5G networks can be accessed by 99% of the country. Other mobile providers pay to share O2’s network, which is a testament to its widespread availability. However, it’s best to check O2’s coverage in your area before signing up.

O2 speed

O2’s coverage is excellent, but it doesn’t deliver the fastest available speeds to its mobile data customers. The average UK O2 download speed is 15.6 megabytes per second (Mbps), which is slower than the speeds of EE, Three, and Vodafone.

Despite this, 92% of O2 users claimed they have ‘adequate’ speeds when browsing social media and the Internet. However, only 75% of O2 customers were satisfied with O2’s mobile data speeds when watching videos.

O2 customer service

O2 offers a good standard of support. In 2021, 91% of O2 customers were satisfied with the service. According to an Ofcom report, its customer service ranking was better than that of Three and Vodafone. However, EE scored 1% higher in this area.

What’s good about O2 benefits?

O2 is known for rewarding its customers with benefits.

  • Roam freely:
    O2 customers can travel to many European countries without paying extra for calls, texts, or data – this is known as free roaming.O2’s Big Bundles are tariffs with unlimited texts and minutes. Purchasing a Big Bundle allows you to use your phone with no extra cost if you’re in O2’s Europe Zone.However, when in this zone, you’ll need to pay more to make calls to countries outside of Europe.

    For countries outside of the Europe Zone, you can use an Travel Bolt On to pay a fixed daily rate for texts, calls and data.

  • Adjust your data allowance:
    By choosing an O2 custom plan, you can change your data allowance every month. This is ideal for customers’ whose data usage varies. For example, if you used 30GB of mobile data during the previous month and won’t need as much this month, you can easily switch to a 3GB monthly allowance.
  • Interest-free financing:
    O2 has long offered monthly payment plans for phones, but this now applies to other devices, e.g. headphones. When purchasing a device, you can choose a 12-, 24- or 36-month payment plan while paying 0% annual percentage increase (APR). However, you may need to pay a small upfront fee.
  • Extras:
    Selected O2 phone, tablet or SIM-only contracts will include a free bonus – known as an ‘extra’ – for up to six months. This might be a Disney+ subscription or an O2 Travel Inclusive Bolt On.

What are the drawbacks of O2?

Although the provider offers great coverage, flexibility, and perks, there are some drawbacks to consider:

  • O2 plans cost more than its competitors
  • Other providers offer faster 4G speeds.

Benefits include:

  • Up to six months of free Apple Music
  • A free O2 extra for up to six months
  • International roaming in 75 countries
  • A three-year warranty when you upgrade your phone.

Plus Plans are available for O2’s phone and tablet deals or its pay-monthly SIMs. You can choose a tariff with a data allowance of your preference.

O2 product Tariff options (monthly data allowance)
12-month Pay Monthly SIM 30GB, 75GB, 150GB or Unlimited data
24-month Pay Monthly SIM 10GB, 30GB, 75GB, 150GB, or Unlimited data
Pay Monthly phone 30GB, 75GB, 150GB or Unlimited data
Pay Monthly tablet Any tariff of 2GB or above

The prices of the Plus Plans will vary depending on your chosen data allowance.

For example, a 150GB 12-month SIM card Plus Plan (£24 per month) costs less than an Unlimited data 12-month SIM card Plus Plan (£34 per month). Similarly, regardless of data allowance, 12-month contracts come with slightly higher monthly costs than 24-month plans, e.g. a 150GB 12-month Plus Plan costs £24 per month, while a 150GB 24-month Plus Plan costs £22 per month.

O2 custom plans

The provider offers you flexibility with its custom plans. These tariffs let you choose:

  • Upfront costs
  • Contract length and monthly payments
  • Your monthly data allowance
  • The included ‘extra’

For example, as opposed to choosing a pre-built plan for an iPhone 13, you can design your own custom plan. In this case, you’re in control of how much you pay upfront for the phone, which can be between £30 or £740. You can then choose a plan length between three and 36 months, and finally, you can choose a monthly data allowance between 3GB and Unlimited data.

The custom plans allow you to pay in a way that suits you. For instance, you could choose to pay £30 upfront for a 3GB per month, 24-month contract – or you could opt for a £50 upfront payment, Unlimited monthly data, and a 36-month contract. Essentially, you can customise and control the costs, data limits, and bonuses as you wish.

This freedom over every aspect of your plan allows you to decide how much you pay each month – which is ideal if you need a new device while on a tight budget.
