Mobile deal data is fetched live from our data platform each time you search or filter, so listings reflect the latest information networks have supplied. Prices and offers can change and may occasionally differ on the network's own website; the network's checkout price is the one that applies. Coverage and speeds vary by network and location, so check Ofcom's mobile coverage checker before you switch. We compare deals from a significant share of the UK market, but no comparison site covers every deal from every network. See how we compare for the networks we include and how results are ranked.
The iPhone 15 launched in September 2023 and now sits as one of Apple's better value buys. It does almost everything most people need, with a 6.1-inch OLED screen, a 48MP main camera and USB-C charging. Pay-monthly deals start from £9.00 a month.
Key takeaways
Key features
The real cost comes down to two figures: the monthly price and any upfront fee. A cheap monthly with a big upfront charge can work out dearer overall, so sort by effective monthly cost to compare deals fairly. Pick a data allowance that matches how much you really use, not the biggest one on the list, and choose a contract length you are happy to stick with. As an older model, the iPhone 15 often shows up at gentler prices than the latest releases, which is the main reason to consider it. If your current phone still works, a SIM-only plan paired with a SIM-free handset is often the cheaper route.
The 6.1-inch Super Retina XDR OLED is sharp and bright for everyday browsing, video and photos. The 48MP main camera takes detailed shots in good light and copes well enough in dimmer rooms, and the 12MP front camera handles video calls and selfies fine. Ceramic Shield Glass adds some scratch and drop resistance, which is handy on a phone you may keep for a few years. There is no telephoto zoom lens here, so you crop in rather than optically zoom for distant subjects.
The iPhone 15 still feels quick for messaging, apps, streaming and most games, though it uses an older chip than Apple's latest models, so it will get fewer years of future iOS updates. That is worth weighing up if you tend to keep a phone for a long time. The 3,877 mAh battery sees most people through a full day, with heavier users likely reaching for a charger by the evening. It charges over USB-C, so you can use the same cable as most newer devices, and it ships with iOS 17.
The iPhone 15 Pro adds a telephoto zoom camera, a faster chip and a more premium titanium build. For everyday tasks like browsing, social and photos in good light, the standard 15 keeps up nicely and costs less. The Pro mainly rewards people who shoot a lot of zoomed or low-light photos, or who push their phone hard with demanding apps. Choose the Pro only if you genuinely want that extra camera reach or the higher performance, otherwise the iPhone 15 covers what most people actually do.
128GB is plenty for casual users who keep photos and apps tidy. Step up to 256GB if you take a lot of video or hold downloads offline, and only pick 512GB if you store large libraries on the device. There is no memory card slot, so you cannot add space later. Choose carefully at the start.

Cons
Our verdict
The iPhone 15 is a smart pick if you want a capable, lighter-on-the-wallet iPhone and can accept an older chip with a shorter update runway.
