As Black Friday 2025 reaches its climax, British shoppers are scrambling to find genuine bargains in the crowded marketplace. The Independent's senior tech critic, Alex Lee, has spent the past decade analysing these sales and has now compiled the most worthwhile mobile phone deals available this Sunday.
Top Contract Deals For Premium Smartphones
For those seeking both a new handset and a service plan, several standout contracts offer remarkable value. The Samsung Galaxy S25 Ultra with 300GB data, unlimited minutes and texts is available for just £28 per month with £219 upfront through Uswitch.com. Meanwhile, Apple enthusiasts can secure the latest iPhone 17 Pro 256GB with an impressive 500GB data allowance for £57.99 monthly with £29 upfront.
Another exceptional contract for the iPhone 17 Pro 256GB with 500GB data appears at £49.99 per month, also with £29 upfront. For those preferring Samsung's premium offering, the Galaxy S25 Ultra with 500GB data costs £29.99 monthly with £229 upfront, providing access to Three's powerful 5G network.
Significant Savings On SIM-Free Handsets
Shoppers avoiding contracts can find substantial discounts on outright handset purchases. The Google Pixel 10 has dropped from £799 to £599 at Amazon, with an additional £100 reduction available using the promo code "PIXEL100" until 30 November. Samsung's flagship Galaxy S25 Ultra sees a £60 reduction at AO.com, now priced at £889 instead of £949.
More affordable options include the Samsung Galaxy S25 discounted by £230 at Laptops Direct, now costing £569, and the Google Pixel 9a reduced from £499 to £347 at Amazon. For folding phone enthusiasts, the Google Pixel 9 Pro Fold sees a massive £993 saving at Backmarket, available for just £756 in refurbished condition.
Budget-Friendly Options And SIM-Only Plans
Consumers watching their budgets have not been forgotten. The Samsung Galaxy A56, 256GB has been reduced by £150 to £349 at Amazon, while the Samsung Galaxy A17, 128GB now costs £139 at Currys, saving shoppers £30.
For those content with their current handset, numerous SIM-only deals provide excellent value. Smarty offers 50GB data for £8 monthly, while Giffgaff provides unlimited data for £15 per month. ID Mobile has a particularly attractive offer with 150GB data starting at £12 monthly, reduced to £6 for the first three months.
Tech expert Alex Lee advises potential buyers: "If you spot a deal that works for you, my advice would be to grab it rather than waiting for Cyber Monday. The best Black Friday phone deals often get snapped up quickly, and popular items with the steepest discounts can go out of stock permanently."
Lee emphasizes the importance of distinguishing genuine bargains from marketing hype, recommending shoppers use price-tracking websites and compare offers across retailers. He particularly warns about contracts with tempting introductory rates that increase significantly later, having specifically sought out deals offering true long-term value.
Most Black Friday sales will continue throughout the weekend until Cyber Monday on 1 December, though the most sought-after devices may sell out sooner. The Independent's IndyBest team tests smartphones year-round, ensuring they only recommend discounts on devices genuinely worth your money.
