Uswitch services are provided at no cost to you, but we may receive a commission from the companies we refer you to. If a deal is "promoted" on Uswitch's tables, then it has been lent additional visibility as a result of us securing exclusivity on a great deal, or a commercial agreement to showcase what we believe to be market-leading value to consumers.

Until 2024, many mobile networks have increased contract prices in line with inflation. Starting in January 2025, Ofcom will introduce a ban on inflation-linked price hikes for new contracts. Future price changes will need to be set and fully disclosed in pounds and pence.
According to a 2024 Uswitch study into mobile phone statistics and usage, over 51% of people surveyed claimed that cost was the deciding factor in choosing a new handset/device.
The latest phones, like Apple’s iPhone 16 and the Samsung Galaxy S25, can cost over £50 per month or more for a contract on some networks, so it can be hard to justify the expense.
With that in mind, we've found the cheapest mobile deals out there for you to compare in our table above.
We think you'll be surprised at the range of great mobile phones and affordable tariffs available.
Compare all mobile deals and offers.
Most mobile networks offer at least one standout cheap mobile phone deal, which is aimed at people who don't want to spend a lot of money on their phone bill each month.
One important thing to consider, though, is that low-cost mobile phone deals come in many forms.
'Cheap' phone deals might refer to mobile phone tariffs with cheap call rates, or it might be taken to mean cheap monthly payments on a great-value talk plan. You might also think a cheap mobile phone deal is one that doesn't have any upfront costs when you sign up.
Selecting the right smartphone deal for you depends on your budget and your usage habits.
Below, we examine the prices you can expect to pay when you sign up with the UK's major carriers and each carrier's selling points.

See our giffgaff mobile deals.
giffgaff call rates and allowances on its SIM only 'goodybags' plans are among the UK's cheapest.
The downside of the low-cost service is that there's no official customer support.
However, the silver lining here is that subscribers can cut more money off their bill by volunteering to help answer customers' questions in giffgaff's user forums.
Browse Vodafone mobile deals.
Like EE, Vodafone is known for premium pricing that reflects its network quality and generous allowances.
However, it could argued that with benefits such as free Spotify and Sky Sports, you're actually getting a pretty good deal for your money.
One of the best ways to get a super cheap mobile phone deal is to opt for a SIM only deal from any of the major mobile phone networks.
SIM only plans, which cover only airtime, data and texts and don't include a new handset, are ideal if you're happy with your existing mobile phone and don't feel the need to upgrade to a newer model.
SIM only deals are becoming more popular because they allow people the ultimate freedom in handset choice as well as the chance to save money.
