Buying a mobile phone - what you need to know
Of course you want to find the cheapest price for your new smartphone - and our comparison chart at the top of the page will narrow that down for you - but we know there are likely to be dozens more questions you'll want answering. Keep reading below, where we answer some of the key commonly asked questions about buying a new mobile.
Can I keep my old number?
You can indeed, and it's really easy - so no need to send one of those texts to everybody in your phone book telling them your new digits.
What you need to do is grab a PAC - or Porting Authorisation Code - from your old network. We've listed the direct numbers you need for the four major networks below. As soon as they've sent it to you, which should be within a day or two, you just need to give it to your new network. Voila - brand new phone with the same old number. Easy.
It becomes slightly less easy if the deal you pick out above is on the same network as your current one. 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 worth it.

Which phone network is best?
Loyalty is an admirable trait, but could end up costing you money when it comes to the perfect phone deal. If you don't mind leaving your comfort zone, you may find that heading to one of the other major networks may well be worth it...
Despite what Richard Branson's adverts might suggest, EE is the Usain Bolt of phone networks. Nobody else can come close to EE's 4G speeds in the UK. So if you rely on fast internet while away from WI-Fi, then EE is the obvious choice. Plus, EE gives you three free months of BT Sport (or more if you get a Max plan) when you sign up, as well as six months of Apple Music. The EE coverage checker will confirm how strong it is where you live.
The biggest lure to O2 is the network's Priority rewards (well, that and Sean Bean's mellifluous tones). From cheap lunches and free coffees to first refusal on big gig tickets, O2 is the network for regular goodies. Plus, they have 1000s of Wi-Fi hotspots in shops and cafes that you can connect to. Use the O2 coverage checker to see whether you'll be able to access 4G.
Good news for jet-setters - Vodafone lets you use your data, calls and texts allowances in 50 countries around the world without charge (except on its Basics tariffs). But things really start to get good when you splash out on its bigger Red Entertainment data plans, as Vodafone will give you your choice of a NOW TV Entertainment Pass, Spotify Premium or Sky Sports Mobile subscription. Click to check if Vodafone covers your home.
3 remains the king of the big data deals, and still the only one of the big four networks to offer unlimited, uncapped, all-you-can-eat delicious data. We also like that you can use 4G to make calls and texts via the dedicated Three inTouch app, and you can connect to Wi-Fi in the London Underground if you ever find yourself in the capital. Its Wuntu app gives weekly perks, too. But 4G coverage isn't as strong as the other networks - check whether your postcode is covered with the Three coverage checker.
What phone contract length should I get?
Well if you're buying a new phone plan with a contract, you haven't got much choice. It's 24 months or nothing, these days. If you don't want to be tied down to that kind of commitment, then you'll have to go down the SIM only route and buy the handset separately - we've rounded up the best SIM free phone deals to help you make your chocie.
How much phone data do I need?
The answer to this one will be different for everybody. If you only really carry your phone for emergencies, then go for the minimum amount of data and save a packet. If you like to scroll through Facebook on the bus and stream Spotify, you'll need a bit more. And if you frequently stream videos and download masses of files, then 30GB or even unlimited may be worth paying extra for.
As well as checking your phone to see how much you tend to use a month at the moment, the below guidelines will also help you pick out the perfect plan:
- 1GB Some networks offer 500MB plans, but realistically we think you should get at least 1GB. It won't be much more expensive (if at all) and will afford you a little bit of Google Mapping, WhatsApping and emailing when you need them.
- 2-3GB If you like to scroll through your social media feeds and emails while out and about without fear of extra cash to pay on your monthly bill, then up your data.
- 4-8GB The likes of Spotify and Apple Music have promised us all our favourite tunes wherever we roam. Kit yourself out with a bit more data and you'll have plenty for music streaming and the occasional video, too.
10-16GB This should be more than enough for most users. Loads of data for streaming music, downloading podcasts and enjoying social media videos. Because there's no such thing as too many cats falling into bins.
- 20-30GB Big data for the big phone user. Perfect for watching Netflix videos, downloading content and streaming loads of music. And these plans often have extra freebies thrown in, too.
- Unlimited The Three network is still the only one of the 'Big 4' to offer unlimited data. It can be really pricey though, so think long and hard whether you really need it.
Should I get unlimited calls and texts?
Actually these days, the vast majority of phone contracts feature unlimited calls and texts. We do see some of the cheaper plans sometimes limit them, but even if they do, you can use your data allowance on popular apps like WhatsApp, Skype and Hangouts to make calls and texts if your minutes run dry.
How much phone memory do I need?
You're likely to be one of two kinds of person:
Person 1: You like all your photos, music, downloads and other media to be saved directly on to your phone. If that sounds like you, 16GB or 32GB handsets may not be enough and you should use our comparison chart to find the most affordable 64GB, 128GB or 256GB models.
Person 2: You're a stream demon. You've got subscriptions to Spotify and Netflix and you save all your Word docs and snaps into the cloud. Save your money and go for a cheaper, lower memory handset.
OK person 3, calm down - you fall somewhere between the two, right? If you can afford to get a smartphone with more memory, that is probably safest. But don't forget that most phones do allow you to insert an additional SD card if you run out of space - most phones apart from iPhones, that is.
Are refurbished phones good to buy?
Refurbished phones can provide a alternative to a new handset if you're budget is a shoestring. 'Refurbished' often means that the previous owner simply changed their mind about the phone soon after buying it, so it's still practically brand new - and the potential savings can be substantial.
If you do spy an unbelievable deal on a refurbed phone, the main thing to make sure of is the warranty. Double check that you are properly covered for a decent length of time. A year's warranty is preferable.

How does TechRadar make money from affiliates?

The money that TechRadar makes from this free service allows us to improve our product comparison tools and pay the editors who trawl through all the sites and select the best deals every month.
While some sites out there will be paid larger fees for pushing people to specific deals that aren't necessarily the cheapest, TechRadar will always find you the absolute cheapest deal. Trust and integrity is important to us, so if you ever think we're not displaying the very best deals let us know.
How do we order these mobile phone deals?
Our mobile phone deal comparison tools sift through millions of different deals and surfaces the ones we think are the very best. Essentially that means finding deals that work out the cheapest over a 24 month contract while still supplying at least 1GB of data, as you've told us that 1GB is your absolute minimum. If you need more data, use the filters and we'll display the cheapest prices for your increased amount.
On this specific page, we have many mobile phone options displaying in one comparison table. In this case, we try and find you a balance between paying the cheapest price and getting the best phone for your money.
How do the mobile phone deals comparison tools work?
The comparison tools you find on the page above will hopefully be very easy to use. You can select what your budget is, whether it be upfront cost or monthly fee or both. And you can say how much data you need or how many minutes and texts. You can even filter by network if you really want to be on a specific carrier. The deals will automatically update as you drill down in your search, always favouring the cheapest options over the more expensive ones. If you ever want to refresh and start your search again, simply select the 'CLEAR ALL FILTERS' option to begin again from scratch.
What is TechRadar?
TechRadar is Europe's largest technology reviews website with over 22 million visitors every month. It's our aim to provide you with the very best buying advice, always. If you'd like to read reviews of the mobile phones you see on this page, you can visit TechRadar's reviews homepage.
How do we select which networks and resellers to display?
TechRadar strives to include all mobile phone deals from all UK networks and resellers so that you can search through all the available deals in the UK without having to look on all the websites separately. However, for sites to be included they need to supply us with a feed of their deals. This is the only reason why a phone reseller or network wouldn't appear in our system – but the vast majority do.

In this section, we've picked out the best deal available right now for each phone, as well as a link through to the 'best deals' guide for each individual handset.
iPhone X deals
We know it's a word that bugs a lot of people, but please let us use it this once - GAMECHANGER. After years of incremental gains and upgrades, Apple finally unveiled a radically improved handset to celebrate the 10th anniversary of the first iPhone.
We've found the best iPhone X deals
iPhone 8 deals
It's really the iPhone 7S by another name, as it's little more than an incremental upgrade on the iPhone 7. And it has had its thunder stolen by the iPhone X somewhat. Wireless charging is the big new feature - the first time we've seen it on an Apple phone.
Samsung Galaxy S9 deals
We really loved the Galaxy S8, so we probably shouldn't be that disappointed that its successor only offers a relatively minor improvement. But to be fair to the latest Samsung handset, the Galaxy S9's cameras are nothing short of extraordinary and it's definitely among the best Android phones on the market.
Samsung Galaxy Note 8 deals
Big in stature and price tag, this 6.3-inch monster will only appeal to people who use their phone as a multimedia hub. It has a QHD+ display and 6GB Ram - phones like the Note 8 don't come around too often.

iPhone 7 deals
Prices on Apple's recently surpassed flagship phone are now finally starting to fall to more palatable levels. We've seen prices as low as £22.99 a month on the UK's fastest 4G network EE!
Samsung Galaxy S8 deals
We were a little surprised by how expensive Samsung's latest flagship was on release, but prices have fallen significantly since then. If you need something bigger and can't stretch to the Note 8, the even larger Samsung Galaxy S8 Plus is closer to a phablet.
LG G6 deals
LG's new flagship phone has a longer screen with a rather fetching rounded-corner design. A fine alternative to the Galaxy's Edge screen and for a lower price.

Samsung Galaxy S7 deals
It may now have been superseded, but the Samsung Galaxy S7 is still a brilliant phone. And now it's a year old, it means you can get big data deals for a reasonable price.
Google Pixel and Pixel XL deals
The Google Pixel replaces the Nexus 5X, comes with a 5-inch 1080p display, 4GB of RAM, 12 megapixel camera and we've seen prices for less than £17.99 a month. The Google Pixel XL is larger and more premium but dearer.

Nokia 8 deals
We're big fans of the Honor 9. It's a genuinely good, new Android mobile at a price you'd expect to pay for a Samsung Galaxy a few generations old. The design is a treat and the 20MP main camera is better than we could have dreamed of.

Sony worked hard to strike a balance between top-of-the-range premium features and affordable prices - it hit gold with the Xperia X and smaller Xperia X Compact.
HTC 10 deals
