LOOKING the best SIM-only deals to help you save money on your phone bill? You’ve come to the right place.
If you’re considering buying a new handset, or you’re existing phone contract is winding down, but you’re happy with your current phone, it’s worth looking at SIM-only contracts, as they can save you a bundle.
For instance, if you come to the end of a standard 24-month contract but don’t need to upgrade, you’ll still be paying full price for your phone, data and minutes unless you change to a different contract.
Before you change to a different network provider, though, check to see if your phone is unlocked and will accept a SIM card from a different network.
You can do that for Apple, Samsung and Google by following those links.

Lebara is also a piggyback network meaning it uses existing coverage from another major provider. Lebara uses Vodafone’s network, so there’s great coverage, and if you have used them in the past and been pleased, you’ll be sure Lebara is just as impressive.
You can get plans from as little as 3GB if you aren’t a heavy data user up to its super affordable Unlimited data plan.
Three has a very customisable set of SIM-only packages, meaning you can choose between rolling monthly contracts and 12-month and 24-month deals.
You can pair that with the amount of data you get, too, so you only pay for what you need.
Vodafone offers a range of pay-as-you-go and pay-monthly SIM-only deals.
The pay-as-you-go packages allow you to roll over your unused calls, texts and data, which is a useful feature.
The pay monthly deals can include things like Spotify Premium, YouTube Premium and Amazon Prime, so it’s worth shopping the deals to see if they’ll save you money when you combine them with your other subscriptions.
O2 allows customers to customise their SIM-only package to suit them.
You can choose between a range of contract lengths, including pay-monthly.
Some of the packages include premium extras, including subscriptions to Apple Music.
EE has tons of SIM-only deals available, including a bunch of massive data offers.
Some of the premium extras include mobile subscriptions to Apple Music, TNT Sports and Apple Arcade.
GiffGaff has many budget-friendly SIM-only deals to browse through, with plans starting at as little as £10 a month for 25GB of data. Ample for those with medium to sparse screen time usage.
If you stream and play on the go, you’ll probably want to take a look at the higher GB plans that offer 500GB of data for just £20 or go unlimited for just £35, so you never have to worry about how much internet you’re using or whether or not you’re connected to the internet.
No matter your usage levels, you’re extremely likely to find the perfect plan for your device with GiffGaff’s 18-month plans.
SIM-only means you’re purchasing a SIM card without a handset, which can be paired with an unlocked phone. The SIM card carries your phone number, contacts list, and text messages, making it easy to swap to a new phone.
There are a huge number of cheap SIM-only deals on the market from all of the biggest carriers, and the key is finding the deal that most closely suits your needs.
The best SIM-only deals will match your level of usage in minutes, text messages and data. SIM-only plans vary in what they offer and for what price, so it’s worth shopping around to find a good deal for your requirements.
Many also offer additional perks and extras to lure new customers in or have exclusive deals for existing customers.
While many SIM-only deals are available on a rolling month plan, which you can cancel at any time, others are 12-month or longer contracts, which you are tied to, unless you want to pay cancellation fees to switch.
To help you compare the best SIM-only deals from all major networks, we’ve included a wide variety of price plans and data limits, so it’s simple to see what’s available.
*Prices in this article are correct at the time of writing but are subject to change. Shop around before you buy a SIM-only contract to ensure you’re getting the best price.
If you are on a budget or are not looking to upgrade your current device, then SIM-only and pay-as-you-go (or PAYG) plans are your best option.
Not only are they more cost-effective, but they also don’t tie you into lengthy contracts, meaning more control is in your hands.
A PAYG plan means you only pay for what you use and no more, so if you don’t need much data or use your device infrequently, then this is the best bet for you.
You’ll want to opt for a pay monthly plan if you know you need a certain amount of data each month and don’t want to have to top up when you run out, these plans also vary in length from as little as 30 days to 12 months, and some providers like O2 allow you to change your tariff during your contract.
The most important things to consider when browsing for SIM-only deals are data allowance, monthly cost, and plan duration. If you can balance these right, then you’ve got the best deal for you.
You want to make sure you aren’t paying over the odds for a small allowance when you could get more for less elsewhere, so be sure to look at our round-up and shop around.
You also need to consider how long you want to be tied to a plan. While they are shorter than a new contract, you don’t want to sign up for a 12-month plan when you only need it for a couple of months.
The main benefit of getting a SIM-only contract is flexibility. Instead of being locked into a two-year contract like you are with most phone providers, you can easily snap up a rolling one-month deal that’s easy to walk away from (although longer contracts are available too and often offer a discount).
SIM-only deals are particularly useful if you’re buying second-hand and refurbished phones; the combination of a cheap handset and a good value SIM-only contract means you can pay much less for the same package than you’ll ever be offered in a store.
If you don’t already own a good smartphone, a SIM-only deal could end up being frustrating, as you won’t have a proper device to make the most out of your data deal, for example.
In cases like this, you could end up saving some money by getting a phone contract, particularly if you’re in the market for the latest phones.
In addition, before getting a SIM-only deal, make sure your phone is unlocked if it isn’t, you won’t be able to use your new SIM card with it.
If you have an iPhone updated to iOS 14, it is very easy to check if your device is unlocked. Simply go to ‘Settings’, then ‘General,’ and finally, tap ‘About.’ You will see a ‘Carrier Lock’ setting there.
If it shows ‘No SIM Restrictions’, your phone is unlocked. Otherwise, there will be the name of a network service provider there, showing that your iPhone is locked to that particular carrier.
With Android phones, the situation is a little bit trickier, as there’s no way of checking if the device is locked via the settings.
Instead, what you can do is simply try a SIM card from a different carrier. If you’re able to make phone calls and access the mobile network after the switch, your phone is unlocked. If you can’t, it is locked.
According to uSwitch, EE offers the UK’s widest and fastest 4G coverage, with a whopping 99% of the UK covered. O2 is a close second, with its 3G/4G connection covering 99% of the country, though speeds are generally a little bit slower than EE’s. Three, Vodafone, and iD Mobile are also valid options, all with coverage rates above 90% nationwide and in many parts of the UK, at fast speeds.
Additional mobile networks with solid coverage are Tesco Mobile, GiffGaff, Talkmobile, and Sky Mobile, together with Smarty, which uses Three’s 4G network.
In terms of 5G coverage, the technology is still patchy across the UK, but Vodafone and EE are at the forefront of the technological race here, with speeds faster than any other mobile network provider.
Yes, but check what type of contract you have.
On some SIM-only deals, you’re locked in for 12 or 24 months, in which case you may be charged an early termination fee.
As a rule of thumb, the early termination fee amounts to the total monthly fees left on your contract at the time of cancellation. So, for example, if there are ten months left in your £10-a-month contract and you want to cancel now, you will have to pay £100.
Yes, it is. All you have to do is wait until your current contract expires (to avoid paying cancellation fees), then switch providers.
To do that, just go to the website of your chosen provider and complete the registration process. A SIM card will then be posted to your address, ready to be activated.
Generally speaking, it is convenient to wait for your current contract to end before starting a new one to avoid cancellation fees.
However, if you find an unmissable deal (or you don’t mind paying the cancellation fee), you can simply start a new contract with them and cancel your current one.
If you’re ending your existing contract and want to keep your number while moving onto another network’s SIM-only deal, you can.
You’ll need to contact your existing provider and request a PAC code. A PAC code will be used by your new network to register your number on their service.
However, if you’re moving to a SIM-only deal on the same network, you may have to change your number unless you do something called double porting, where you switch your number to another provider and then switch back.
If you migrate your old number to a new SIM card, you can destroy the old one, as it will be deactivated the moment the number is transferred.
If you start a new contract with a new phone number, however, your old SIM will stay active for a while. In that case, you may want to keep your old SIM if you intend to use it again.
Just a heads-up, if you have any credit left in your old SIM card, you may want to use it, as if left unused, it may expire after six or 12 months.
Potentially, yes.
Whether or not the provider will run a credit check on you, a SIM-only contract will involve a credit agreement. Because of this, you could build up your credit rating by keeping up with your monthly SIM-only contract payments.
Legally speaking, there’s no minimum credit score needed to get a phone contract, but some companies will run a check anyway. Different network operators will also score you differently, so if you can’t get a contract with one, you could try checking with others.
For context, 30-day rolling SIM-only contracts do not usually require credit checks since they are extremely low-risk to the company. However, if you’re signing up for a 12 or 24-month SIM-only contract, it is more likely that they will check your credit score.
Here’s a selection of mobile phone networks which have great SIM-only deals:
To find out how much data you use each month, simply log into your account with your provider, check how much data you use each month, and buy a SIM-only plan accordingly.
Some SIM-only providers, such as Voxi, offer unlimited social media data too, which means you might get through a little less data than normal. If you burn through data very quickly, some providers, such as Smarty, offer unlimited data packages for as little as £18 a month.
You’d think companies would try and lure customers in by giving them lower prices on 12-month SIM-only contracts, but that’s not necessarily the case.
The decision to get a short-term or a long-term SIM-only contract should be made on a case-by-case basis.
There are three sizes of SIM cards available: standard, micro, and nano. The size you’ll need depends on your phone and should be made clear in your handset’s instruction manual.
As a rule of thumb, iPhones tend to take nano SIMs, Samsung Galaxys take micro SIMs, and standard SIM cards have been relegated from the mainstream altogether.
Each phone will have a different method for changing the SIM card. Head to the brand’s website to find out how to swap yours:
