The best smartphone and SIM-only deals for Black Friday 2023

With this unlimited SIM-only plan, you’ll never have to worry about running out of data while streaming or browsing social media on-the-go. For Cyber Monday, you can get six months of the 24-month plan at half price (£15 instead of £30) – pop this into your phone and you’re ready to go. It includes unlimited minutes and texts, too.

The Pixel 8 Pro is one of the best Android smartphones you can buy, with a stunning camera system, smooth performance and seven years of software support. This deal via Affordable Mobiles gives you that phone for £39 per month with no upfront cost, and the data has been increased from 100GB to 400GB just for Black Friday and Cyber Monday. Even better: you can claim a Fitbit Charge 6 at no extra cost. This is a 24-month contract plan.

Voxi’s £10 per month plan is one for social media fans. This lets you use up to seven apps in the UK without eating into your data. For Black Friday and Cyber Monday, the brand is giving you loads of extra data at no extra cost – rising from 15GB to 60GB. One of our favourite aspects of Voxi is that it’s not a lengthy contract: it’s a rolling 30-day subscription and you can cancel the plan anytime. That's much better if you prefer flexibility.

If you already have a smartphone but want to upgrade the data plan, we would consider this Black Friday and Cyber Monday offer from Three. Listed as the temporary Black Friday price on its site, the network provider is giving you unlimited data for £20 per month (on a 24-month plan). This SIM deal also has unlimited calls and texts, and 5G.

We’ve been tracking the best Sky Black Friday offers throughout this month, and one of our favourite smartphone discounts is on its 12-month contract SIM-only data plans. Until 30 November, you can claim 40GB of data for £12 a month (was £24) or 100GB of data for £18 a month (was £36), plus you also get unlimited calls and texts.

There are few phones as powerful as the S23 Ultra – it takes great pictures, has speedy performance and comes with a built-in stylus that’s great for note-taking or drawing. As part of its Black Friday sale, the brand is giving you £250 off, so the flagship phone is now £999 from £1,249. Simply enter the code S23ULTRA250 at checkout.

This notable Black Friday and Cyber Monday offer on the iPhone 15 at Mobiles co.uk (a division of Currys) reduces the upfront cost from £99 to £0. You’ll get 300GB of data for the monthly cost of £39 (24-month plan). This is one of the best iPhone 15 offers we’ve spotted so far, as many others are £40+ per month and charge upfront costs.

If you want to buy an affordable phone outright and prefer Android over iOS, we highly recommend the Google Pixel 7a for its smooth performance and excellent cameras at a value price. For Black Friday and Cyber Monday, Amazon cut the price of the handset to £379 from £449 – but, unlike other retailers, it bundles in an official 30W wall charger.
