Black Friday 2025 has sparked a fierce price war on the latest smartphones, with Samsung's flagship Galaxy S25 at the centre of the action. While Sky Mobile has launched its sale with significant cuts, our investigation has uncovered an even more compelling two-in-one offer from a lesser-known retailer that savvy shoppers won't want to miss.
The Standout Samsung S25 Deal
Mobiles.co.uk, which is backed by retail giant Currys, is currently offering what might be the most attractive Samsung Galaxy S25 package available. Shoppers can secure the device for £27.99 per month with a £29 upfront cost on iD Mobile's network. The real value, however, lies in the enhanced data allowance and storage upgrade that comes standard with this deal.
This contract not only provides a substantial 500GB of data per month – a significant increase from the usual 100GB allowance on this tariff – but it also delivers the 256GB storage model of the Galaxy S25 for the price of the 128GB version. This dual enhancement represents exceptional value for money during the Black Friday sales period.
How Sky Mobile's Offer Compares
Sky Mobile entered the Black Friday fray with an apparently cheaper proposition for the Samsung Galaxy S25 256GB, pricing it at £24 per month with just £12 upfront. However, this seemingly lower cost comes with a major limitation: a meagre 100MB data allowance that's insufficient for most modern smartphone users.
Heavy data users would need to supplement this basic plan with one of Sky's additional data SIMs, which could see monthly costs escalate dramatically. Adding 40GB of data costs an extra £10 per month, while unlimited data pushes the additional cost to £22 monthly. When factoring in these necessary additions, the total monthly bill could reach as high as £46, making it considerably more expensive than the Mobiles.co.uk offer over the 24-month contract period.
Total Cost Analysis and Important Considerations
Shoppers who take advantage of the Mobiles.co.uk deal will pay a total ownership cost of £739.76 over the full 24-month contract term. This works out considerably cheaper than purchasing the phone outright from either Samsung or Amazon, where the same 256GB model currently retails for £859.
Potential customers should be aware of one important detail: the monthly bills are subject to increase during the contract term. Those on the £27.99 tariff will see their payments rise to £29.49 from April 2026, with a further increase to £30.99 from April 2027.
Elsewhere in the Black Friday market, giffgaff has also launched a competitive offer, providing the Galaxy S25 256GB with unlimited data for £31.09 per month and £20 upfront, representing a saving of approximately £300 from the usual cost.
The Samsung Galaxy S25 has earned impressive feedback from consumers, achieving an outstanding 4.8-star rating on the Samsung website. One satisfied customer praised the device, stating: "Such a quality phone. I got this for the camera, and this is amazing, but all the other features make it an even greater purchase than I thought it would be." Another highlighted the phone's AI features and battery life, particularly noting its ability to "last a full seven hours" while streaming music.
