Best Sim-only deals

If you're buying a phone outright, you'll need a Sim card. Here's our pick of some of the best low, medium and high-data deals in the sales.

Best low-data Sim-only deals 

You shouldn't pay for data you don't need, so if you're a particularly light user, opt for a cheap monthly contract that gives you the ability to switch around as circumstances change. Here are some highlights:

Lebara Mobile – 3GB of 5G data for £1.99 a month. It's a one-month contract, but you'll get the first three months at £1.99 if you stick with them, before it rises to £5.99. You get unlimited minutes and 5G speeds. If you want to know more about the provider first, read our Lebara Mobile review.

Smarty – 4GB of 5G data for £5 a month. Smarty is including EU roaming in this low-cost Sim deal that's ideal if you don't need a lot of data. It's on a one-month contract too, so it won't tie you down. Read our Smarty review to see how it fares in our survey.

Talk Mobile – 5GB of 5G data for £2.98 a month for the first three months, then £5.95 a month. This Sim-only contract with 5GB of 5G data and unlimited minutes is a great deal. Read our Talk Mobile review if you want to see how customers rate it.

Best medium-data Sim-only deals

These deals could be suitable if you use your mobile data fairly frequently but don't require large amounts of data for activities such as HD downloading or streaming. Here are some highlights:

O2 Mobile – 20GB of 5G data for £8 a month. This great deal comes with 5G data, unlimited minutes and texts, and three months free Disney+ on a 12-month fixed contract. Plus, you'll receive special offers with O2 Priority. Read our O2 Mobile review to see how customers rate it.

iD Mobile – 20GB of 5G data for £8 a month. The deal includes unlimited minutes and data rollover, so unused data can be saved in a piggybank. This is the better option for iD's low and medium data deals, as the other is £8 a month for 15GB. Our iD Mobile review reveals how well it did in our survey.

Talk Mobile – 15GB of 5G data for £3.98 a month for the first three months, then £7.95 .This rolling one-month contract comes with unlimited minutes and texts and 5G speeds. If you want to know more about the provider first, read our Talk Mobile review.

Best high-data Sim-only deals

High-data deals are ideal for those who need it for continuous connectivity, downloading, streaming and hotspot use. These types of deals will often require a 12-month contract, so consider how committed you want to be and how much data you're likely to use. These are some highlights:

Talk Mobile – 50GB of 5G data for £5.97 a month. You only get this price for the first three months, but even at the regular price of under £11.95 it's reasonable. If you want to shave a little more money off, a similar deal on 40GB of data is available at half price - £4.98 a month, for the first three months. 

Smarty – 100GB of 5G data for £12 a month. This is a great deal on a rolling one-month contract, offering you a large amount of data at a fixed price (£12). Even better, you get EU roaming as part of your plan. You can also get unlimited data for £16. Read our Smarty review to see how it fares in our survey.

iD Mobile – Unlimited 5G data for £16 a month. A great deal that includes unlimited minutes and texts with super fast 5G data, on a rolling monthly contract. Read our iD Mobile Review to see how it fared in our survey.

Best mobile phone contract calculator

A key question will be whether you buy outright or on contract. How much each will cost overall can be difficult to work out, so use our calculator below to discover the best deal for you.

Pros and cons of pay-monthly contract mobile phones

With a traditional pay-monthly contract, you pay a fixed minimum monthly fee by direct debit, which is made up of paying for the phone (usually through a credit agreement, meaning you get credit checked) and the Sim itself, with an allowance of calls, texts and data. You'll have to commit to a period of time, typically two years. Depending on your plan, there may also be an upfront fee, which is something worth considering if you're set on a contract. 

What are the advantages of monthly contracts? 

  • Free/cheap phones With a monthly contract, you'll get a wide choice of free or subsidised handsets, which is ideal if you fancy an upgrade. 
  • Good value Paying in advance for a fixed amount of minutes, texts and data can be much cheaper than topping up a pay-as-you-go phone. 
  • Hassle free You’ll never get cut off because you’ve forgotten to top up your credit. 
  • Can build your credit score Paying off a mobile phone contract monthly can be a good way to build your credit score. Bear in mind that missed payments or defaulting can make your credit score drop. 

Are there any drawbacks with pay-monthly contracts?

There are a few. As mentioned, you may end up paying more overall, so you'll need to weigh this up against the appeal of a lower upfront cost.  

Pay attention to the length of the contract. Most last two years, but some can last three, in order to keep the monthly cost looking attractive. You should also make a note of when your contract ends. Some providers continue to charge you the full monthly cost, even after your contract has been paid off. 

If you exceed the minutes, messages or data in your bundle, additional charges can be significant. It's especially important to be aware of this while roaming. Most providers now set a default 'cap' to prevent this, but if you remove it in order to continue using your phone, costs can quickly spiral out of control. For more, read our guide on how to keep track of your minutes and data, and our guide on EU roaming and international calls. 

Consider network reception with a great mobile phone deal

Signal is another consideration. If you know a particular network is good for your area, you may want to stick with it, but move to a different provider. Or if it isn't, it could be time to move. 

Here are the core networks the virtual providers use:

  • O2 Giffgaff, Sky Mobile, Tesco Mobile
  • Vodafone Asda Mobile, Lebara, TalkTalk, Voxi
  • EE BT, Plusnet, Utility Warehouse, Virgin Mobile
  • Three iD Mobile, Smarty Mobile

When it's time to switch mobile phone provider

If all else fails, it might be time to switch. Outside the big four – EE, O2, Three and Vodafone – a wide range of operators are now competing for your business, and some offer great-value Sim-only deals. Switching is easy and you should be able to keep your old number.

Arming yourself with a price you could get elsewhere is an important haggling tactic. Compare mobile phone contracts and Sim-only deals to find out how much you could be paying.

Smaller mobile networks consistently do better than the big four (EE, O2,Three and Vodafone) in our mobile networks survey. Read our guide to the best and worst UK mobile networks to find out more.

How to get the best mobile phone deal on popular brands

Generally, you'll find the best deals on mobile phones at retailers such as Amazon, Currys and John Lewis, rather than on the manufacturer's website. However, knowing when the best sales are for specific mobile phone brands can be useful if you're trying to find the best deal on a specific model you want. 

iPhone deals

It's notoriously tricky to bag an iPhone on a budget – even older iPhones don't tend to see too many discounts. They hold their value better than older Androids, so you often see them on the second-hand market.

However, if you look in the right place at the right time, you can get some money off. Retailers such as Amazon and Argos occasionally bring their prices down, although you should make sure you're buying a new rather than refurbished handset.

New iPhones usually launch in September, so the end of the year is a good time to look for the previous models, particularly as the Black Friday and Christmas sales roll in.

Apple also offers a trade-in scheme, so you can knock down the price of a new handset slightly if you're upgrading from an older iPhone.

Browse all our iPhone reviews to see how all of Apple's handsets scored in our lab tests.

Google mobile phone deals

Google launches its flagship phones in October, so it's worth putting a Pixel on your shortlist late in the year.

You'll see the biggest bargains on older handsets, but even more recent phones can get some early discounts at major retailers such as Carphone Warehouse and Laptops Direct.

See if it's worth investing in a Pixel by reading our Google Pixel reviews.

Samsung mobile phone deals

If you're after a Samsung Galaxy on a budget, you might be tempted by some of its reasonably priced handsets from its A, J and M ranges. Mid-range models have come on leaps and bounds over the past few years, and spending £300 to £400 can get you a slim, stylish and powerful model that may not look too different from a high-end version.

If you have your eyes on the premium prize, though, it could be worth holding out for a top-of-the-range Galaxy S or Note series. Samsung's S series usually launch in the first quarter of the year, with the first discounts on the latest handsets beginning in the summer. It's worth keeping an eye out on Amazon Prime Day in July.

Phones in the Note range tend to launch in August, so new models are ripe for a decent discount when Black Friday rolls around. If you miss out, the Boxing Day sales are a good time to buy, too.

We've reviewed more than 40 Galaxy phones. Pick your perfect model in all our Samsung phone reviews.

Mobile phones and security updates

Deals on phones are more common when they've been out for a little while, but depending on the brand and handset, this could mean they won't be receiving security updates for much longer. Check our security update calculator for models you're interested in buying. See mobile phone security
