The Big Deal has had plenty to say about the Samsung Galaxy S9 since it was presented to the world with only a little less fanfare than Prince Louis. But prices haven't been cheap since the phone went on sale in mid-March – the S9 is a phone most definitely aimed more towards princes than paupers.
Well, at least it was until last Friday, when Carphone Warehouse-owned Mobiles.co.uk delivered a Galaxy S9 deal on contract that blew the rest out of the proverbial. £23 per month. £180 upfront. 4GB of data and unlimited calls and texts. As deals go that's about as beautiful as a new-born babe.
Perhaps the most outlandish thing about this deal is that over the course of the two-year contract, the total amount of money you'd pay actually equates to a few quid less than the £739 RRP of buying the Galaxy S9 SIM-free outright.
And if you did splash the cash on the phone, you'd then have to pay at least £4 a month for a SIM plan – and for £4 you'd only get the bare minimum of data, text and call allowances, so chances are you'd be paying more, pushing your total spend over 24 months north of £900.
So has going for a contract mobile phone deal overtaken the handset + SIM only as the best-value way to pick up your new smartphone? The Big Deal has taken a look at four other mobile models – young and old, premium and budget – to see which will save you the most cash. We'll tell you the current cheapest contract plan for each, and the cost if you combine an outright purchase with the best equivalent SIM only deal.

iPhone X deals: contract vs SIM-free
Yep, let's start with the daddy (no WIlls, not you). Apple's 10th anniversary device is the most expensive mainstream mobile on the market. But the iPhone X is so damned captivating, with features like Face ID andit's the extraordinary 5.8-inch Super Retina HD display, that it's worth knowing how to shave off the £££s where you can.
Today's best contract price: £1,344 over two years
Three is currently in pole position when it comes to the phenomenal iPhone X. That's thanks to this deal that costs £56 a month and absolutely nothing at all upfront (opens in new tab). You get 8GB of data per month and perks from Three, like its Wuntu app for cheap lunches, prize draws and the odd free coffee.
Equivalent handset + SIM only: £1,223 over two years
There's a very tasty £100+ saving to be made here if – and it's a huge 'if' – you have £899 to spend upfront. That's how much you can get an unlocked iPhone X for at Amazon.co.uk (opens in new tab) at the moment. From there you can grab an 8GB Tesco Mobile SIM only deal (opens in new tab) for £13.50 per month. This is the route to go on the iPhone X at the moment.
Samsung Galaxy S8 deals: contract vs SIM-free
So we know that the new Samsung on the block – the Galaxy S9 – has got some remarkable prices right now, but what about its princely predecessor? We usually find that going back a generation means you can get an incrementally less advanced smartphone for a much better price. And we still have a lot of love for the Galaxy S8. So should you go contract or SIMO?
Today's best contract price: £692 over two years
Much like the limited-time S9 deal, Vodafone's 4GB tariff is the place to be for the Galaxy S8 (opens in new tab). Using our exclusive 10OFF code, you can bring the total price down under the £700 mark. It makes the upfront outlay £140, with monthly bills of £23. Tremendous value.
Equivalent handset + SIM only: £699.99 over two years
Trawl the depths of eBay and you eventually trip over this: a brand-new Samsung Galaxy S8 for £459.99 (opens in new tab). That's a good start. From there you can then add a 5GB per month Vodafone SIM (opens in new tab) for a tenner each bill. That takes you up to a penny under £700 for the term, so a tiny bit more expensive than contract, but you do get 25% more data – there's very little in this one.
Google Pixel 2 deals: contract vs SIM-free
With its Pixel range of smartphones, Google has really been knocking on the door of the big two, Samsung and Apple. Although it didn't improve hugely on the original, we admire the Google Pixel 2 for its powerful speakers, water-resistant frame and magnificent main camera. It's a tempting pretender to the smartphone crown, but how should you buy it?
Today's best contract price: £815 over two years
Okay, so this may not be the very cheapest Pixel 2 deal out there right now, but it's certainly the best value. 16 glorious gigabytes of data a month on Vodafone for a mere £30 a month (opens in new tab) and £95 upfront (after using our 10OFF code). Really strong from Mobiles.co.uk, this.
Equivalent handset + SIM only: £989 over two years
Well there's a clear winner here. Contract deals on the perky Pixel 2 are so good at the moment that buying the handset outright and popping in a separate SIM is waaaay pricier. The cheapest you can buy it SIM-free is £629 from Currys (opens in new tab), and then Three's £15pm SIM (opens in new tab) takes it towards a grand for the two-year term – and that's only for 12GB of data, too.
Moto G5 deals: contract vs SIM-free
Don't fancy spending a king's ransom on your new blower? Well we can't say we blame you. The Moto G5 tops our charts of the best cheap phones your budget will allow, and we can't see that changing – at least not until the Moto G6 hits the shelves. Despite the price tag, you still get an attractive metal design, HD display and fingerprint scanner. Very nice.
Today's best contract price: £383.76 over two years
On the face of it, this is a pretty attractive offer: £15.99 per month to get the Moto G5 on Plusnet from Direct Mobiles (opens in new tab). For that you get 2GB of data, unlimited texts and 1,200 minutes of calls every month. Sounds good, right? Well hold your horses for just one second...
Equivalent handset + SIM only: £239 over two years
AO.com is currently flogging the SIM-free Moto G5 for a fantastic £119 (opens in new tab). From there you can then pick up a 2.25GB SIM from iD (opens in new tab), which is Carphone Warehouse's own network. That costs a crazy fiver a month, making the total cost over two years the smartphone deal equivalent of robbing the crown jewels in broad daylight.
And the crown goes to...
Erm.. .well this is embarrassing. We've heard of a hung parliament, but did a coronation ever end with no clear king or queen?
The truth is that the best option depends entirely on what phone you're buying. On the budget side of the spectrum, it's almost always going to be cheaper to buy the handset and then grab one of our best SIM only deals to put in it.
But, as you can see if you contrast the iPhone X with the Samsung Galaxy S9, there's no formula for which option will be more affordable as you get to more premium devices. And then there's the likes of the Galaxy S8, which is a toss-up either way.
Once you've chosen the handset you want, the best way to make sure you're getting the best value is to stick with TechRadar's bespoke price comparison charts. We have all the information on the best contract deals, cheapest SIM-free prices and those SIMO plans, too. Long live the savings...
