O2 was founded in 1985 and was previously owned by BT Group. The network operator was then bought by Spanish telecoms giant Telefónica in 2006.
Like its major UK competitors, O2 offers pay-monthly handset contracts, Sim-only deals and pay-as-you-go bundles. It’s worth noting that customers looking for pay-monthly contracts with the latest handsets are typically tied into a 3-year contractual commitment.
The operator is also the sponsor of The O2 complex in London, previously known as the Millennium Dome. This commercial partnership allows O2 to offer its mobile customers priority access to all events at O2 Academy venues as part of its customer loyalty scheme.

Regulator Ofcom carries out a survey of mobile network customers every year to gauge their satisfaction with their provider. Results from 2020, for which full data is available, shows that 91% of O2 mobile customers told Ofcom that they were satisfied with the overall service they received. This is just above the average score for the industry overall that year (90%).
However, only 79% of O2 mobile customers reported that they felt they received value for money from their carrier. This is below the average score of 83% among all large mobile operators over the same period. O2 would have been the worst performer on this score, had it not been for Vodafone’s customers giving their provider a “value for money” score of 77%. During this time Ofcom received 8 customer complaints for every 100,000 O2 mobile customers, the fourth lowest proportion after Tesco Mobile, Sky Mobile and EE.
Meanwhile, O2 customers using reviews site Trustpilot appear to be extremely unhappy with the service they receive, giving the network operator a paltry overall score of 1.4 stars out of 5. A convincing majority of the 6,100 customers who left reviews (71%) said their experience with O2 was “bad”, with only 16% giving the top rating of “excellent” (last updated: October 2021).
As one of the UK’s largest mobile network operators, O2 provides wide coverage across the country. It also offers a wide choice of contract options both for those looking to buy a handset on a contract and those who need a SIM-only deal. O2 customers can also benefit from some nifty customer rewards, particularly when it comes to booking tickets for large concerts and events.
However, as outlined above, O2 is rarely the cheapest option for any type of mobile plan. It’s also worth noting that its pay-monthly contracts can be up to 36 months, which is a long time to be committed to your mobile operator. If you have the cash upfront, you may be better off buying your preferred handset upfront, as with pay monthly contracts you’ll end up paying more over the long-term.
While customer service reports are mixed, if O2 provides the best mobile reception where you live, you may want to give them a go. Just don’t expect a spectacular customer experience.Ready to compare mobile plans?

Which O2 mobile plan would be the cheapest for me being an OAP?
Hi John,
Thanks for getting in touch with Finder. I hope all is well with you. :)
That would depend on your needs and preference, John. You can start using O2 mobile plan for as low as £10. However, that is for the basic service. You will incur the standard rates for calls, texts and data usage if you don’t have the minimum credit amount for their pay as you go bundle plans.
On our page, the cheapest plan from O2 is £9.99 upfront. Please check our table and see which plan would best meet your needs and budget.
I hope this helps. Should you have further questions, please don’t hesitate to reach us out again.
Have a wonderful day!
Cheers,

My elderly mother is in a care home and needs us to be able to phone her. What is the best SIM card option. I have already sourced a DORA handset for her.
Hi Jeremy,
