The cheapest 24-month deal on each network, sorted by the true total — the headline total plus the April rises the network has announced.

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 iPhone 15
The cheapest way to get the iPhone 15 on contract today is on iD Mobile: £139 upfront and £14.99 a month with 200GB of data, £541.96 over 24 months. At the other end of our table, Three’s best deal works out £190.24 dearer once rises are counted — the same phone, so the network choice alone is worth that much.
iD Mobile adds £1.80 a month every April, so a contract started now costs about £43.20 more than the headline figure: £541.96 in all. Networks without an annual rise are worth a look if the gap is small.
Buying the iPhone 15 SIM-free costs from £529. Pair it with a SMARTY 30-day SIM at £6 a month and two years cost £673, £131.04 more than the cheapest contract. Here retailers discount the handset to win the airtime, so the contract wins on price.
The iPhone 15 has a 6.1-inch screen, a 3,877 mAh battery, a weight of 171 g. It is on sale with 128GB of storage in 4 colours. It was released in September 2023.
