O2's deals and incentives
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 charges 30p/minute, 15p/text and £1/50MB for its pay-as-you-go (PAYG) deals. You can also buy bundles – for example, paying £15/month for 6GB data and unlimited minutes and texts.
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'.
Complaints about O2
Telecoms regulator Ofcom regularly publishes information on the number of complaints it gets about the main mobile providers.
In its latest report, covering the third quarter of 2019 (July to September), O2 generated a very low level of complaints – three per 100,000. While it can't quite match Tesco Mobile's rate (one per 100,000 customers), it's below the level of complaints generated by Vodafone and Virgin Mobile (seven per 100,000).
