The best O2 phone deals in December 2020

As one of the four main networks, O2 has been a go-to choice for many over the years. And recently, O2 phone deals have been offering some of the best prices around, making it a logical option for anyone looking to save on their contract.

However, these great prices aren't coming from O2 itself. In fact, the O2 website seems to often struggle to match the value that can be gained from going to 3rd party retailers (like Carphone Warehouse or Affordable Mobiles). Those are the places the really strong O2 phone deals can be found.

And despite stiff competition from the likes of Vodafone, EE and a host of MVNOs, O2 has stood its ground as one of the best networks available. It's the network renowned for its extra Priority reward giveaways and customise-able plans.

But of course, the main question is what are the best O2 phone deals? For anyone who's mind is set on flagships, you'll find great offers on the likes of the iPhone 11, Huawei P30 Pro, Samsung Galaxy S20 Plus and Google Pixel 4. And O2 even holds its own in the budget department with everything from Samsung to Moto and back again.

And if the O2 phone deals you've found are being offered by retailer Mobiles.co.uk and costs at least £10 upfront, then make sure you enter our exclusive 10OFF discount code at the checkout to knock a tenner off.

Price Comparison chart

The best iPhone 12 Pro deals on O2:

The iPhone 12 Pro and the larger 12 Pro Max are Apple's most impressive and powerful phones to date. Both come with 5G, a triple camera set-up, massive batteries and the market's most powerful processor. But with all of that comes a large price tag as well.

The best iPhone 12 Mini deals on O2:

The iPhone 12 Mini is the smallest 5G phone on the market and the cheapest of Apple's four iPhone 12 handsets. Despite its size and cheaper price tag, it comes with 5G, Apple's super-powered A14 Bionic chip and a whole host of other impressive features.

The best iPhone 12 deals on O2:

The iPhone 12 is the middle of Apple's new devices, it blends a more affordable price than the Pro with a more powerful design than the Mini. It comes in at a size of 6.2-inches and features the same 5G, powerful processor and more.

The best Samsung Galaxy S20 Plus deals on O2:

The Samsung Galaxy S20 Plus was one of the other big launches from Samsung's S20 range. It provides impressive specs at a price tag that is rapidly falling. In fact, we would go as far to say that with its large battery, powerful processor and overall top-notch performance, the S20 Plus is the best phone on the market.

The best Samsung Galaxy S20 deals on O2:

The latest in Samsung's long line of devices, the Samsung Galaxy S20 is packed full of high-end specs, offering a massive 4000mAh battery, a triple camera set-up and even a hefty 8GB RAM.

The best Huawei P30 Pro deals on Vodafone:

While the Huawei P30 Pro is no longer the brand's newest device, it remains its best. That is because Huawei fell into a disagreement that meant it could no longer use Android services and therefore, it's latest devices can't access the Google Play Store.

However, the Huawei P30 Pro avoided this issue due to its older age. This means that with a far lower price tag, the Huawei P30 Pro is a great option for many.

The best iPhone 11 deals on O2:

The iPhone 11 has come along to offer fans of Apple a 2019 device without going all out on cost. It arrived with a SIM-free price less than the iPhone XR on release while boosting specs in almost every department - better screen, the fastest CPU on the market and a much needed battery development.

Samsung Galaxy Note 20 deals on O2:

Every single year, Samsung's Note design keeps getting better and better. The latest iteration - the Note 20 - is clearly a combination of everything Samsung does well. Yes, the display is only Full HD but through the use of Samsung's 'S' pen and its improved latency, an impressive battery size, a beautiful (but unfortunately not curved) design and a top-tier set of cameras, the Note 20 is one of the best Samsung phones you can buy right now.

The best iPhone SE deals on O2:

This 2020 launch from Apple rewards you with its cheapest iPhone yet! Don't be fooled by the design. While it looks and feels like an iPhone 8, it is packed with some seriously powerful specs including the same processor found in the iPhone 11 series.

Google Pixel 5 deals on O2:

Google's latest handset came along to compete with the flagship devices from Samsung, Apple and OnePlus. It brought what it did best - a top-notch camera - but paired it with an improved battery, a better processor and all-round better phone, making Google more competitive than ever.

FAQ on O2 phone deals

What are the benefits of O2?

When it comes to benefits of a O2 phone deal, the best known part comes in the form of O2 Priority. This is a scheme which offers the likes of competition entries, free tickets, coffees and other benefits.

Those that sign up with O2 also get access to events that O2 is sponsoring and most importantly, O2 covers 98% of the UK when it comes to coverage meaning you should never be worrying about signal. 

Can I keep my number when I switch to O2?

You sure can, if you switch over to an O2 mobile deal and want to keep your old number, then simply call your old network, get a PAC code and transition it over. 

If you were previously on O2, you can still keep your number but it is slightly more complicated. They won't let you keep your number, so you have to use this workaround. Buy a free pay-as-you-go SIM from any other network and tell your network that you're moving. 

They'll release the PAC code, which you then give to the substitute network. Then, you immediately get another PAC code from them. Take that to your old network, and they'll move your number to your new contract. Long winded, but easier than learning a new number!

Can I use my O2 phone abroad?

Like all of the other networks, O2 covers your roaming charges when you're in Europe. Stray out of that area and you will have to start paying additional costs for the data, minutes and texts you use.

Travelling outside of Europe? O2 has a number of different schemes and packages to help you deal with that - you can find them all on the O2 website

Can I get an unlimited data O2 phone deal?

O2 is the final of the big four - O2, EE, Vodafone and Three - to offer unlimited data plans. Unfortunately for anyone considering going all out on their data, O2 is probably going to be one of the more expensive ways of doing it. So far, it seems that Vodafone deals and Three Mobile deals will land you the best price on unlimited data.

Can I get an O2 phone deal with no upfront costs?

Luckily, there is a huge amount of O2 phone deals that require no spending at the start. In fact, phone contracts with no upfront costs are a frequent sight in the phone market. Obviously as soon as you cut upfront costs, the monthly cost does tend to receive a bump. But if you're lucky it could end up being a complete bargain.
