The best OnePlus 6 deals in May 2021

The OnePlus 6 has been out for a while and has now been replaced by the newer 6T device so if you want the newest phone go to our OnePlus 6T deals page. But that definitely doesn't mean this is no longer a worthwhile device, and the flagship phone still looks able to stand toe to toe with similar 2017 (and even 2018) devices. Our expectations for a proper premium smartphone were met and exceeded - and OnePlus 6 deals are still worth your time.

While the OnePlus 6 'only' has a full HD screen, it's a 6.28-inch display that crams as much screen as possible into the real estate, and yes that means there's a notch. It's also packing dual rear-facing cameras, face unlock and a fingerprint scanner, plus up to 256GB of storage. And as well as the specifications, the glass design really elevates it into the upper echelons of today's crowded smartphone market.

Check out our interactive comparison chart to find your perfect OnePlus 6 deal - ranging from big data needs to the lowest price. O2 has network exclusivity, but you still need to choose the ideal data allowance and price point for you. If you want the handset on it's own, without committing to a contract, we've got the best price and where to find it as well.

Unlocked OnePlus 6 SIM-free deals

The OnePlus 6 is available SIM-free via the OnePlus website, with prices starting at £469 for the 64GB/6GB configuration. If that's not quite enough storage for you, maybe the £519 128GB/8GB variant is more up your street. Finally there's the most expensive OnePlus phone ever, the 256GB/8GB model that comes in at £569.

If you have that kind of cash sitting around, it's well worth trying to figure out the best SIM only deals for your needs, as you could end up saving a packet overall. They start from under five pounds per month and give much more flexibility than getting locked into a contract.

The OnePlus 6 felt like the brand's most grown-up phone upon release, and doesn't feel out of place sat alongside current flagship devices like the iPhone X, Sony Xperia XZ2 and LG G7 ThinQ.

It manages this thanks to an all-glass design that feels truly premium, a fluid performance, a bright and colorful 6.28-inch screen, and a solid camera experience. The cameras may be the same as the OnePlus 5T, but that's no bad thing. 

It's possible to criticise the lack of expandable storage, but with in-built storage that goes up to 256GB, storage isn't something you'll struggle for. It's worth noting that it doesn't have an official IP rating, stereo speakers, or a microSD card slot, but otherwise looks to be a great flagship phone.
