Three Mobile offers pay-monthly and pay-as-you-go phone deals with the newest smartphones, as well as SIM-only and pay-as-you-go plans for customers who already have an unlocked smartphone. Three phone deals always provide unlimited texts, unlimited minutes and the data allowance you want, from anywhere between 1GB of data and unlimited data.
Three offers the latest iPhone, Samsung Galaxy and other Android devices, with unlimited minutes and texts plus data plans allowing up to unlimited data.
All Three Mobile deals require a phone contract with a minimum term of 24 months, which is a long-term commitment. Over the course of 24 months, you pay a standard monthly cost for the mobile and the airtime plan. While the price rarely changes over the course of the contract, Three can’t guarantee that there won’t be a slight price rise as a result of inflation.
In addition to the monthly cost of the contract, there’s also a one-off upfront cost to pay when you first join. This is usually between £20 and £90. You’ll need to pay this fee to get the pay-monthly handset you want.
Take a look at our list of Three’s best pay-monthly deals in March 2024 with iPhone, Samsung, and other Android devices.
Replace your Apple iPhone XR or iPhone 11 with a newer version, such as the iPhone 12 or iPhone 13. Three is currently offering these iPhone deals for half-price for the first six months as part of its winter sale. These include:
Add AirPods Pro to any of these mobile phone contracts for under £10 a month. The contract length on AirPods is also 24 months. There’s also always the option to cancel your contract early but you will have to pay an exit fee. In any case, there’s a 30-day notice period to end a phone contract.
Replace your Samsung S9 or S10 with a newer Samsung Galaxy, such as the S20, S21 or S22, that has a more high-profile camera and faster processor. At the time of writing, Three is offering half-price deals for the first six months on the following pay-monthly deals:
When you buy a Galaxy S22 series, you get an additional 12 months of the Disney+ TV channel free of charge.
Three offers great deals on other smartphone brands such as Xiaomi, Google, OPPO, Nokia, OnePlus, TCL, and Nokia. Its best handset deals are the following:
These smartphones are available with various data plans; the above are just the most popular phone and data combinations among Three customers.
SIM-only deals offer unlimited minutes, unlimited texts and the data plan of your choice. Three offers phone contracts of different lengths: a one-month SIM, a 12-month SIM or a 24-month SIM. You can choose from the following SIM-only packages:
Data plan | Monthly cost |
---|---|
4GB | £19 |
12GB | £22 |
30GB | £24 |
Unlimited | £28 |
Data plan | Monthly cost |
---|---|
1GB | £7 |
4GB | £10 |

There’s also the option of 2GB for £7 a month, but this comes with a limit of 200 texts per month.

All of the SIM-only deals listed above are Three Advanced Plans, which come with extras including:
A pay-as-you-go (PAYG) plan will only charge you for the allowance you use. You get your PAYG mobile SIM card for free, after which you only pay for texts, calls and data usage. Here’s how much you’ll be paying for a Three PAYG SIM:
There’s no phone contract with PAYG, nor are you tied to a minimum term. Just use your phone when you like and you’ll be charged accordingly. This plan is ideal if you use your mobile phone irregularly. If you’re a heavy phone user, you might find that it’s cheaper to get a SIM-only contract.
Three also offer pay-as-you-go phones. You’ll need to pay the full price of the phone and a one-month data pack to get started. Then the phone is yours and you get to decide when you top-up again.
Choose your airtime with a Three Data Pack. These are a flexible way to top up your data as you don’t have to commit to a long-term contract. You can get your Data Pack on Amazon:
To get a Three Data Pack you need your own personal mobile phone, then you simply insert the SIM card once you’ve received it in the post. Data Packs are different to pay-monthly plans because there’s no contract and you decide when you top-up your airtime plan.
If you’re a business owner, Three has a price promise for you: if you find a cheaper monthly mobile contract with Vodafone, EE or O2, Three will beat it by at least £1 a month.
Business plans are available to everyone, regardless of whether you’re a new or existing customer. Follow these steps to get your business plan:
Three mobile deals come with several perks to offer both new and existing customers. Take a look at what you could benefit from by joining Three:
Three has exclusive offers for new customers. As a new customer, you can receive the following when you sign up for a mobile contract:
Existing customers get exclusive deals on mobile upgrades. If you already have a handset deal with Three and are looking for a new device, save money by taking a look at the provider’s upgrade options.
If you decide to upgrade, return your old device to Three, who will recycle it. The provider will pay you for recycling your old phone, allowing you to make a profit and help the environment at the same time. Your old phone will be used for parts or be repaired, ensuring it doesn’t end up in a landfill site.
Use the provider’s website to get a quote on how much you’ll be paid for your old phone. Once Three receives your phone, its team will assess it and confirm its value. You’ll then receive your money within 24 hours of confirmation.
Receive up to £80 when you refer a friend to Three. To recommend a device to a friend, you’ll need to request a link, which you then need to send directly to your friend. Once your friend makes the purchase via the link, you’ll receive your money.
Get a data boost if you’re running low on data. Choose from 1GB, 3GB, 6GB or unlimited data. Once you add a data boost to your plan, it will renew automatically every month. You can cancel it at any time through the Three app, for which there is a 30-day notice period.

Spend Cap helps you manage how much you spend outside your monthly allowance. Set it to anything up to £100 and you’ll have data access even if your allowance runs out before the end of the month. Three will warn you when you’re about to reach your limit to help you keep your bills under control.
If you want to switch off all additional chargeable services, you can set your Spend Cap to £0. To make changes to your Spend Cap, just use the My 3 app.

Three was awarded the prize for Best Network Data Award at the 2021 Uswitch Awards. The provider also won the 2021 Ofcom award for Best Value for Money, both for pay-monthly contracts and SIM-only plans.
Three uses its own infrastructure. It’s one of the UK’s ‘big four’ mobile networks and is not a Mobile Virtual Network Operator (MVNO), therefore it doesn’t piggyback on another network’s technology.
