Most people already know that a “free” phone on a contract is never actually free. The cost of the handset is baked into your monthly bill, spread out so thinly that you stop noticing it.
By the time your two years are up, you’ve often paid hundreds of pounds more than the phone was worth. Here’s where that money goes, and let’s see if we can find a cheaper way to handle it.
How Contracts Hide the Real Price
When a network advertises a shiny new phone with “nothing to pay upfront”, they’re lending you the money for the handset and charging it back through your monthly payments. Networks tend to obscure the total cost of a phone contract because breaking it into smaller, manageable monthly payments looks more affordable than a large lump sum. It’s a loan dressed up as a phone deal.
The numbers add up fast. Take the iPhone 15 as an example. At one point, EE was offering it at £34.86 a month over 24 months with £30 upfront, which works out at £866 for the handset, £67 more than buying it outright from Apple at £799. Add the airtime on top and you’re paying well over the odds for the convenience of not handing over cash on day one.
It gets worse with mid-contract price rises. Most UK networks bump up their prices every April, and if you’re locked into a 24-month deal, walking away usually means paying an early exit fee. Ofcom’s new rules from January 2025 mean providers now have to spell out any rises in pounds and pence before you sign, but the rises themselves haven’t gone anywhere.
The True Cost of Contracts
Once you separate the phone from the airtime, the savings become obvious. Buying the same iPhone outright and pairing it with a SIM-only plan saved money over two years, and the gap widened further on a cheaper network. Using a piggyback network like Lebara, which runs on VodafoneThree network, will always be much cheaper in the end
You don’t need a brand-new flagship to make this work either. A refurbished phone does the same job for a lot less. Refurbished phones typically cost 30 to 50% less than new equivalents, with some models offering savings of up to 70%. These aren’t dodgy hand-me-downs.
Reputable sellers typically offer up to 70% off compared with new, a one-year warranty and 30 days to change your mind, with clear condition grades like Good, Very Good and Pristine.
Then you can pick your own airtime. A cheap 30GB SIM-only plan from a provider like Lebara will cost you around £10 a month with no contract and no credit check, which is plenty of data, minutes and texts for most people. Because you own the handset, you’re free to switch deals whenever a better one comes along instead of being tied to one network for years.
Why People Are Already Switching
This isn’t a fringe idea anymore. SIM-only deals now make up half of all pay-monthly mobile subscriptions, up from 44% a year earlier according to Ofcom, and more people are holding onto their phones for longer rather than upgrading every two years. The cost-of-living squeeze has pushed more people to look closely at what they’re actually paying.
The savings add up. Switching from an ending 24-month handset contract to a SIM-only deal and keeping your existing phone could save around £304 a year, roughly £25 a month. Buy a refurbished handset on top of that and you’ll often end up with a better phone than the “free” one you were offered.
There’s a small catch worth knowing. If you buy refurbished, check the phone is unlocked, ask about battery health and stick to a seller with a proper warranty. Get those three things right and the risk is tiny.
The Maths Doesn’t Lie
The “free” phone trick works because it hides the price in plain sight. A few pounds a month feels harmless, but stretched over two years it quietly drains your wallet. Buy a refurbished handset outright, add a cheap SIM-only plan, and you’ll usually pay less, get a better phone and keep the freedom to walk away whenever you like.
Ofcom’s own pricing analysis says it’s almost always cheaper to buy a handset outright and pair it with a SIM-only deal than to take a combined contract, so the maths backs this up rather than just being a money-saving hunch. Spend ten minutes with a calculator before your next upgrade and the gap will speak for itself.
