Best Black Friday iPhone deals
Apple iPhone 8 64GB silver
Apple's latest iPhone has been met with praise from critics and fans alike. The sole criticism was its hefty price. It comes with a lightning fast processor, wireless charging and a stunning screen.
But you can get it today from 02 from mobiles.co.uk (part of Dixons Carphone) with a massive 12GB of data from just £32 per month with an upfront cost of either £190 - or only £175 upfront with the deal code below.

iPhone SE 32GB sim free
If you're after something smaller and cheaper from Apple look no further than the iPhone SE, one of the most powerful four-inch phones ever made. It boasts many of the same features as its larger siblings, most notably an excellent camera.
iPhone 7 32GB
The fantastic iPhone 7 is available from just £19 per month from Virgin Mobile, an incredible price given it was starting at more than £40 per month last year when it was released. This model comes with 32GB of storage and has a fast processor, all-day battery and comes with the latest iOS 11.
This deal only has 300 minutes and 1.2GB of data, but there are bigger data deals available. One caveat with Virgin deals is these are 36 month prices, however you are able to change your monthly plan every month.
Best Black Friday Android smartphone deals
This is easily the cheapest we have seen the brand new Nokia 8, and it comes with 64GB. For just £359 you get a powerful handset with almost two days of battery life, a brilliant dual camera and a wickedly fast processor.
It comes in sleek blue and silver colours. The SIM-free phone means you can also pick a cheap SIM-only deal to go with your phone, potentially saving you money compared to many contract offers.
Wileyfox Swift 2
Wileyfox is a British company taking on mobile phone behemoths like Samsung and Apple, and their devices have received rave reviews.
This version is a sleek smart phone with 32GB of memory, 3GB of RAM and a five-inch screen; it runs on the latest Android Nougat operating system and has a top-quality camera. What's not to like?
Sony Xperia XA1
There's almost a quarter off one of Sony's most popular smart phones. It comes with 32GB of memory, 3GB of RAM and 4G network technology.
The 23 mega pixel camera will enable you to take top pictures for social media and an external memory card slot allows you to increase memory to up to 256 GB.
Sony Xperia X1A
Save as much as £60 per month with Tesco Mobile on this cut price deal. It comes with 5,000 texts and 500MB of data, which is not a huge amount, but at just £13.49 per month it is a tiny price to pay for the beautiful Sony Xperia.
Google Pixel 2 64GB black
Google's Pixel 2 was launched last month to rave reviews in the Telegraph, praised for its beautiful design, excellent operating system and having one of the best phone cameras out there.
It's an expensive phone, but it's now available for only £29 per month on 02, one of the lowest prices we have seen. Click below for the voucher code.

The Moto G5 is one of our favourite budget smartphones. It has 2GB of RAM and 16GB of storage, not much, but at this price it is still a punchy smartphone with strong performance. It's powerful enough to whip through most tasks and comes with a 13MP rear camera.
Right now it is just £129 from Amazon, a great price for one of the best budget smartphones of the last 12 months and perfect for someone who doesn't need the very latest tech, but still needs a reliable, powerful phone.
Best Black Friday Samsung deals
Samsung Galaxy Note 8 64GB black
The best sim-free offer on the brand-new Samsung Galaxy at the moment. The phone has received excellent reviews; it's the best Samsung yet.
The Galaxy Note 8 is the bigger, beefed-up version of the Galaxy S8, and runs on the latest version of Android and features Samsung's first dual-lens camera.
Samsung Galaxy S8
The Samsung Galaxy S8 has a 12mp camera, infinity display and high quality sound. This is a 30 month credit contract which includes your phone and tariff: you can upgrade whenever you like and pay less when the contract is up.
You can read The Telegraph's review of the Samsung Galaxy S8 here, which describes it as "almost inarguably the best-looking phone ever made" and "a brilliantly-designed phone that sets a new standard for what phones should look like in 2017."
Samsung Galaxy S8 with 500MB of data
This is an incredible price for the state-of-the-art Samsung Galaxy S8. The phone comes with an edge-to-edge display, a powerful camera and a bright and punchy screen, plus voice commands from its Bixby assistant.
When this phone came out you would be lucky to find it for less than £40 per month. Now this deal from Carphone Warehouse sees it down to just £29 per month with 500MB of data from iD Mobile.
Samsung Galaxy S7 Edge
This is one of the cheapest SIM-free offers we have ever seen for the Samsung Galaxy S7, widely regarded as the best phone released in 2016.
