bemobiles tips
Is the lowest monthly price the best deal?
In this case the lowest monthly deal is also the cheapest overall, but always check the upfront cost and the 24-month total.
What will April price rises add?
Talkmobile has no annual price rise on this deal, so the total is what you pay. Other networks add up to £60.
Should I buy it outright instead?
Not today. SIM-free plus a cheap SIM costs £161.20 more over two years than the cheapest contract.

Rises use each network’s announced amount in pounds (Tesco Mobile about 6%). Sky Mobile’s rise isn’t fixed in the contract, so it isn’t included.

Our take on the Galaxy S25
The cheapest way to get the Galaxy S25 on contract today is on Talkmobile: £295 upfront and £11.95 a month with 15GB of data, £581.80 over 24 months. At the other end of our table, Vodafone’s best deal works out £149.20 dearer once rises are counted — the same phone, so the network choice alone is worth that much.
This deal has no annual price rise, so £581.80 is what you pay over the two years — rare on a phone contract and worth weighing against slightly lower headline prices elsewhere.
Buying the Galaxy S25 SIM-free costs from £599. Pair it with a SMARTY 30-day SIM at £6 a month and two years cost £743, £161.20 more than the cheapest contract. Here retailers discount the handset to win the airtime, so the contract wins on price.
The Galaxy S25 has a 6.2-inch screen, a 4,000 mAh battery, a weight of 162 g. It is on sale with 128GB of storage in 3 colours. It was released in January 2025.
