The Samsung Galaxy S9 has been unveiled, and it's available to buy now. Samsung announced its new flagship at MWC 2018 in February, alongside a bigger S9 Plus. Here, we bring you all of the pricing and information you need, including S9 SIM-free options and S9 contracts.

You can find out everything you need to know about the two new phones, including details on their new and improved camera features and a first look at the new AR Emoji in our news round-up here or our Galaxy S9 review here.

If you've already done your research and are convinced that the S9 is the phone for you, read on for details on how and where to buy it.

Samsung Galaxy S9 SIM-free deals

You can buy the Samsung Galaxy S9 SIM-free from a huge number of retailers and networks, as we outline below.

Its RRP is £739/US$719.99, but it's worth keeping in mind that, unlike iPhones, Samsung phones often fall rapidly within the few months following the launch. If you can wait a few months you may well get a better deal, but if you're keen to get your hands on the S9 as soon as possible continue reading for the best prices today.

Click the links below to find the Samsung Galaxy S9 SIM-free. The SIM-free price is the same across the board at the moment, at £739, so it'll really be up to you which retailer you choose to buy from. The differences come in when we start to look at contract deals, which you'll find later in this article.

Carphone Warehouse S9 deals

Carphone Warehouse has some particularly good deals available if you're intending to trade in an older phone. You can get up to an extra £50 on top of your trade-in value, making the up front cost on some of these deals significantly lower.

  • EE, 20GB data, unlimited texts and minutes, £209.99 upfront, £38 per month. Free Samsung Convertible Wireless Charger included. 3 months free BT Sport, 6 months free Apple Music. Available from Carphone Warehouse here.
  • EE, 15GB data, unlimited texts and minutes, £129.99 upfront, £48 per month. Free Samsung Convertible Wireless Charger included, 3 months free BT Sport, 6 months free Apple Music. Available from Carphone Warehouse here.

e2save S9 deals

e2save is a subsidiary of Carphone Warehouse, also offering great deals for the S9.

EE S9 deals

EE offers low upfront costs and big data for the S9. We found one deal that might be worthwhile, but the others are a little pricier than those offered by the likes of Carphone Warehouse and Mobiles.co.uk and others, so we wouldn't recommend them.

  • 60GB data, unlimited texts and minutes, £10 upfront, £68 per month, 24 months BT Sport app access. Available at EE here.

Fonehouse S9 deals

Deals from Fonehouse are competitive, so might be worth investigating. Many offer a free phone and some have cashback promotions available too.

Giffgaff S9 deals

Giffgaff's deals are a little different from others listed here. You can choose whether to buy the S9 outright or pay for it monthly, but either way you'll want to choose a goodybag for your minutes, texts and data.

The £15 goodybag is a good one, offering unlimited texts and minutes with 6GB data. Sign up here.

Mobiles.co.uk S9 deals

Carphone Warehouse-owned Mobiles.co.uk has some really great low-cost options available for the S9.

Mobile Phones Direct S9 deals

Mobiles Phones Direct is another great place to look for low-cost deals, as it often has some of the best on the market. Our pick of the best right now is this one:

O2 S9 deals

O2 is offering the S9 through its O2 Refresh plans. They're 24 months long and include a Device Plan and Airtime Plan separately to make upgrading or keeping the phone beyond the contract length easier to manage.

We've picked out just one deal from O2 as it's a good one for lots of data and the reassurance of a screen replacement. Others are available but they're quite pricey for what you get so we'd recommend looking elsewhere.

  • 50GB, unlimited texts and minutes, £49.99 upfront, £68 per month, free screen replacement and upgrade after 12 months. Available at O2 here.

Sky Mobile S9 deals

Sky Mobile's deals are a little different from many of those in this article. Its Swap24 and Swap12 plans make payments cheaper, but at the end of your contract you can either send back your handset in return for a newer model, or choose to keep the phone at a lower monthly rate.

Sky's deals could be an option if you're a Sky TV customer, too.

Three S9 deals

Three's S9 deals don't always work out the cheapest, but there are some advantages. For example, you'll get 12 months of Netflix included, and watching Netflix using your data won't eat into your data allowance thanks to the Go Binge feature.

Virgin Mobile S9 deals

Virgin Mobile offers something unusual that might appeal if you plan on keeping your new phone for longer. Its 36 month deals keep monthly costs down and if you're a Virgin broadband and TV customer you may find there are other perks available.

Vodafone S9 deals

Vodafone's deals offer low upfront costs, and some offer perks such as Spotify, Sky Sports or Now TV.

  • 32GB, unlimited minutes and texts, £29 upfront, £65 per month. 24 month subscription to Spotify, Sky Sports or Now TV included. Available from Vodafone here.

Samsung Galaxy S9+ SIM-free deals

The SIM-free price of the S9+ is a little more pricey, at £869/US$839.99. For now, all of the places listed below are offering the S9+ for the same price, but as mentioned previously, Samsung phones tend to go down in price after a few months with various retailers promoting special deals.

Samsung Galaxy S9+ contract deals

We've picked out the very best S9+ deals from around the web here, and you can read on for a customisable comparison tool and more deals from retailers and networks.

Top S9+ deals

As above with our S9 comparison tool, you can use the tool below to find the best prices and contracts to suit your needs for the Samsung Galaxy S9 Plus. Beneath the comparison tool we also have a hand-selected assortment of our favourite deals so far, which we are adding to as more emerge.

Carphone Warehouse S9+ deals

Carphone Warehouse is running a promotion that could get you up to £50 extra on top of your trade-in value when buying anS9+, so keep that in mind if you plan to trade-in an old phone, as it could significantly reduce the upfront cost you see here.

  • EE, 25GB data, unlimited texts and minutes, £249.99 upfront, £53 per month. Free Convertible Wireless Charger included, free 3 months BT Sport, free 6 months Apple Music. Available from Carphone Warehouse here.

e2save S9+ deals

A relative of Carphone Warehouse, e2save has some good offers for the S9+.

EE S9+ deals

EE has a good deal for low upfront cost and big data, but the monthly cost is huge and other deals available are more expensive than those offered by the likes of Carphone Warehouse and Mobiles.co.uk.

  • 60GB, unlimited minutes and texts, £10 upfront, £78 per month 24 months BT Sport app access. Available from EE here.

Fonehouse S9+ deals

Fonehouse's S9+ deals are worth a look.

  • Vodafone, 40GB, unlimited minutes and texts, no upfront cost, £61 per month with £60 cashback available. Available at Fonehouse here.

Giffgaff S9+ deals

Giffgaff offers the option to pay for the S9+ outright, or monthly. You'll need to add a goodybag to that to get your data, texts and minutes.

The £15 goodybag will get you 6GB data and unlimited texts and minutes. Sign up here.

Mobiles.co.uk S9+ deals

Mobiles.co.uk is owned by Carphone Warehouse and offers some brilliant deals that are well worth checking out. Here's a our favourite:

Mobile Phones Direct S9+ deals

We've seen some brilliant deals from Mobile Phones Direct with no upfront cost, which is a huge plus if you haven't got savings available right now.

O2 S9+ deals

O2's deals can be quite pricey, but there are some big data offerings that might be worth considering. Particularly because they're on O2 Refresh and you'll be able to upgrade after 12 months if you choose. You'll get a free screen replacement should you break your new phone too.

  • 50GB, unlimited minutes and texts, £49.99 upfront, £73 per month, free screen replacement. Available from O2 here.

Sky Mobile S9+ deals

Sky Mobile's deals are unusual. Its Swap24 and Swap12 plans can reduce costs and allow you to upgrade more regularly in the case of Swap12 which lasts just 12 months, but rather than keeping the phone at the end of your contract you choose to either send it back in return for a newer model, or keep your phone at a lower monthly cost. Sky TV customers can get discounts on these contracts, too.

Three S9+ deals

Three's deals aren't the cheapest available, but if you watch a lot of Netflix they could be well suited to you. You'll get 12 months of Netflix for free, and Three's Go Binge perk means watching Netflix without WiFi won't eat into your data allowance.

Virgin Mobile S9+ deals

Virgin offers some reasonable monthly prices and no upfront cost, but the catch is you're tied in for 36 months. There are 24 month deals available at higher prices, but they're not as competitive.

Vodafone S9+ deals

Vodafone's deals for the S9+ are pretty pricey, but you will get Vodafone Global roaming and some plans include 24 month subscriptions to streaming services.

  • 32GB, unlimited texts and minutes, £99 upfront, £69 per month. 24 months Spotify, Sky Sports or Now TV included. Available from Vodafone here.
