Before signing up for a new phone deal, read our review of O2 to see how it scored in our annual mobile network customer survey.

O2 has its own network and offers 2G, 3G, 4G and, more recently, 5G coverage.
In our latest analysis of 4G phone coverage, performed in conjunction with coverage experts RootMetrics, we found that O2 had the weakest overall performance.
You can check coverage where you live by using our free interactive . Simply enter your postcode into the map and it will tell you how good O2's signal is in your area, as well as comparing it with the other providers.
O2 splits its pay-monthly 'Refresh' packages so you'll actually be signed up for two deals – one for your minutes, texts and data (the airtime plan) and one for the cost of your phone handset (the phone plan).
Once you've paid for a handset (at the end of your contract), your bill is automatically reduced. In contrast, most other providers will keep you on a higher tariff until you tell them to switch, even when you've paid off your phone – a practice we don't think is fair. Refresh also lets you easily upgrade to another phone by simply paying off the balance owed on your existing handset.
O2 is also known for offering perks, including O2 Priority. This gives customers access to a range of offers, including pre-sale tickets. There is also the O2 Rewards scheme for PAYG customers, which gives you back up to 10% of your quarterly spend on credit.
O2 is one of the UK's biggest mobile phone providers and has hundreds of high street stores, many of which offer technical support from the company's 'O2 Gurus'.
