How to get the best price on your mobile phone contract and save

You’re likely paying hundreds of pounds too much on your mobile phone.

For the first 12 years of having a phone, I followed the same pattern. A two year contract with a shiny new handset, which was then renewed with an upgraded phone, and then repeated when each contract ended.

But a decade ago I switched things up. I moved my tariff to a new network, and bought a new handset direct from Apple. Since then I’ve moved between networks on a regular basis and bought and sold new handsets. And saved a ton of cash.

And you can do it too: from going SIM-only through to downsizing your data, there’s no reason you should be paying more than £8 to £10 a month. Here’s how you can save on your mobile phone contract.

Split your handset and your tariff

Go SIM-only

The best prices are often with SIM-only deals. Here you keep your old handset or buy a new one separately and pay just for your minutes, texts and data. Since you aren’t paying for a new phone, the monthly costs are also considerably less. 

You can get contracts that run from 30 days to a year, giving you far more flexibility than the 18, 24 and even 36-month deals you’re tied to with handsets (though longer SIM-only deals are still available).

At the time of writing you should be able to get a more than adequate data allowance from the major networks for under £10, and potentially as low as £5 or £6 for networks offering 5GB. And that’s before you factor in cashback or other offers.

Don’t get your handset via your network

Once you go SIM-only you’re no longer caught in that bi-annual cycle of getting a new phone when you don’t really need to. Ideally you’ll keep your handset for more three or four years. But with poor batteries, broken screens and “depreciated” operating software (when updates are no longer supported on older phones), we all need to upgrade at some point.

However, you should avoid getting one as part of your contract. Most networks will charge you a premium on top of the handset price to get a new phone bundled with your SIM.

It’s very, very rare for these deals to work out cheaper, particularly for the latest handsets. Instead, you’ll save money buying it outright from Apple, Samsung or the likes of John Lewis.

Of course, the high cost of these handsets can be a barrier, but even then you don’t need to resort to including it in a contract. Apple and Samsung offer 0% finance for two years, while you could choose a 0% purchase credit card instead. Do check your credit score first though.

Don’t forget to sell your old handset too. There are a number of sites that’ll give you a fixed amount, or you can hope for a better price via sites like eBay. Here’s more on selling old phones.

Choosing your new phone tariff

Whether you stick to a combined phone and SIM deal or split them up, you can still bring down the cost.

Don’t pay for more data than you’ll actually use

One of the biggest ways we waste money on our mobiles is via upselling, and now the networks are all about getting us to pay for more data than we need.

A few years ago when I haggled a new SIM-only contract with Three, the salesperson said “It’s only £3 more for 20GB”. Sounds good. Except I didn’t need 20GB. I didn’t really need the 12GB I have (but that was bizarrely cheaper than the 5GB option).

And I see this upselling all the time. There are always a number of promotions offering unlimited data at what looks like fantastic prices. But you really don’t need unlimited data, so however good the price, you’re still overpaying.

Most of you will be fine with 4GB or 5GB, perhaps less, and it’s easy to check your usage history. I’ve written here about how you can work out exactly how much data you need.

Factor in the extras and freebies

I wouldn’t recommend choosing a new phone network based purely on extras, but if prices are similar it’s worth seeing what you can get.

Ones to look out for include:

  • Free streaming services (e.g. Disney+, Netflix etc)
  • Loyalty apps (O2, Three and Vodafone)
  • European or worldwide roaming

Bear in mind when it comes to O2 Priority or Vodafone’s VeryMe rewards that both are still available if you’re with a different network if you pay £10 – that might work out cheaper.

Saying that, those who also get broadband with Virgin Media should take a look at O2 as you’ll get double data, worldwide roaming and double internet speeds via an offer called Volt. Just make sure you’re getting a decent price on each service.

Don’t just stick to the big companies

You’ll have spotted that most of the cheap deals are with smaller networks. And I bet you’re warry of switching in case you can’t get reception.

Well, there are actually only four different phone networks – O2, EE, Three and Vodafone. All the others “piggyback” on one of these. So, for example, Giffgaff runs on O2 and Lycamobile uses EE.

This means you get exactly the same reception as someone on the host network but at a far lower price. The only real difference will be in customer service, though you’ll also lose network-specific benefits from the big brands, such as O2 Priority Moments.

I’ve written in more detail about these so-called “virtual networks”, including which ones operate on which main network.

It’s also relatively easy to bring your number with you. My moves across different networks all took less than 24 hours though it might take longer if weekends or bank holiday get in the way. Just ask for a PAC number, which you can get just by texting your network.

Finding the best price

Don’t wait for your contract to end

One of the worst tricks networks would use to make extra cash was to let you keep paying for a phone and SIM after a contract had ended. This meant many people would still be paying for a handset even after they’d covered the cost.

However, rules from Ofcom mean most mobile networks will let you know when your contract is due to end and if you can get a better deal with them.

This is a great nudge, but even if you’re offered a cheaper deal, it doesn’t mean you’ll be on the cheapest deal out there – as the following tips will show. 

Plus, the rules currently only apply to tariffs purchased directly from the network (i.e. not from an online or high street phone shop), and not all networks have signed up, with Three the main big name missing from the agreement.

Personally, I’d not wait for this to happen as you can usually negotiate with your network up to 30 days before the end of a contract. This gives you the chance to see if you can get a better deal with your current network, and if not start the process of moving to a cheaper one.

Compare prices

Just as you would with your gas or broadband, it’s important to see what other networks are offering. MoneySupermarket or BillMonitor are decent price comparison sites, though they don’t include all the SIM-only networks.

You’ll also often find lower prices for the big networks via these sites, allowing you to access some (though not all) of the freebies available by those companies.

Make sure you also check retailers such as Carphone Warehouse too as they often have their own deals.

Check for cashback

If you’re switching network or upgrading without a new handset there’s less of a chance for cashback, but it’s worth checking anyway. Try both Topcashback and Quidco for SIM only too. And if you’ve never used cashback sites don’t forget the new member bonuses to get even more back!

You can also earn cashback to knock more off your bill using the app Airtime Rewards, but only with the major networks and a handful of others.

Call your network to see if they’ll negotiate

It’s still worth calling your network to see if they can match or beat the total savings you’ll find from the tips above. It helps to do some research first so you know what you can get if you switch.

Then ask to be put through to the ‘terminations’ or ‘disconnection’ team as they’ll usually have more sway. You can even do this over live chat if you prefer.

I did this the most years with Three. I either had my price knocked down or data added for the same price, beating what I’d get elsewhere. None of these deals were available on the Three website, but came from saying I wanted my PAC.

A warning here though. You will be starting a new contract if you do this, which will overwrite pre-existing offers such as free roaming with some networks.

    Suggest expand article to include Affordable Mobiles and e2save. Both ignore tracking through quidco and tcb tho.

  2. I’m sim only with Three and was £9 for 4gb unlimited calls and text then they upped the price for the same calling it a brand new deal for £14… They just go round and round in circles not giving me a straight explanation for this

    1. Definitely call up and say you want to leave and ask for your PAC. Say you’ve seen 8GB or £8 online for new customers so you want that. You don’t actually have to leave if you don’t want to, but it helps to get the best deal if they think you will.

  5. Hi, I am o GiffGaff too but thinking about moving to TalkTalk for a year to get the same vale for half price since I am already their customer so they can offer mi half price SIM Only deal. I see there are plenty of SIM ONLY deals available to compare on comparison sites such as uSwitch – worth checking if one is not sure what t o choose 🙂
