There's no denying it, O2 has had some of the absolute best mobile phone deals of late, especially on the higher-end of the smartphone market. Throughout January so far, some of our favourite offers have been on the network. Big data, cheap monthly costs or freebies to entice you in, O2 has had it all in early 2019.
Whether you're in it for the Priority rewards or O2's brilliant countrywide coverage the network is know for its high quality, making it the second most used in the UK. But going straight to O2's website isn't such a good idea, as the prices tend to be higher than you can find from other third-party (but still utterly trustworthy) retailers. They're where you'll find the very best O2 mobile phone deals, with our top five favourites picked out below.
We know you may have concerns with very recent memories of signal issues plaguing O2. They seem to have now been sorted. But if they still give you cause to avoid O2 or if you simply want to know all your options, then you can always head to our best mobile phone deals page to see what the likes of EE, Vodafone and Three can offer.
