The best iPhone XR deals on O2:
The iPhone XR hits a sweet spot between high tech and reasonable pricing. It looks a lot like its more powerful brethren – both in appearance and on the spec sheet – and boasts a glorious 6.1-inch Liquid Retina display and A12 Bionic chipset without a £1,000 price tag.
The best Samsung Galaxy S9 deals on O2:
OK, so the Samsung Galaxy S9 doesn't make massive strides on the S8, but that doesn't mean it's not still one of the best Android phones on the market right now. The cameras in particular are awe inspiring and tangible improvements have been made to both the biometrics and position of the fingerprint scanner.
The best iPhone XS deals and iPhone X deals on O2:
Oh gosh, Apple went and did it. After years upon years of incremental upgrades, it finally made something special to celebrate the 10th anniversary of the iPhone. For the iPhone X it has dropped the bezel altogether, while the 5.8-inch Super Retina HD is scarily good – and then it tweaked things a year later for the XS. Marvellous!
The best Samsung Galaxy Note 9 deals and Note 8 deals on O2:
Samsung has now well and truly put the flaming memories of the Note 7 in the past. If the Note 8 was exceptional (6.3-inch infinity display and 6GB RAM), then the Samsung Galaxy Note 9 is even bigger and more powerful (6.4-inch infinity display and 8GB RAM). If you want the best big screen Android phones on the market, then look no further.
The best iPhone 8 deals on O2:
Thanks to the spectacle that was the iPhone X launch, the reception for the iPhone 8 was a little bit flat. Which we think is unfair – it improves on the iPhone 7 with wireless charging and an improved camera. Plus, it's quite a bit cheaper. So if you're looking for the best iPhone but the price of the iPhone X is too much to cope with, try the 8 on for size instead.
Best Samsung Galaxy S8 deals on O2:
There's no doubt that the Samsung Galaxy S8 is a fantastic phone. The lightning fast chip-set and introduction of its infinity screen makes it the premier Android experience. And now that the S9 is here, it's no longer even that expensive.
The best iPhone SE deals on O2:
The iPhone SE looks and feels exactly the same as the iPhone 5S. But instead of sporting two-year-old hardware it's been updated, with a faster CPU and graphics, and the 12MP iSight camera straight out of the iPhone 6S. It's a modern iPhone in the shape of an old iPhone, for people who like the old iPhones but want more up-to-date hardware.
The best Google Pixel 3 and 3 XL deals on O2:
The Google Pixel 3 and 3 XL are relatively new devices on the flagship scene but they have very quickly become two of our favourites. Powerful processors, loud speakers, but most importantly they have what is arguably the best cameras you can get on a phone right now.
