The best SIM only deals in February 2017

We dig out the best SIM only deals so you don't have to

SIM only deals become very popular around this time of year as people keep hold of their existing phones after taking advantage of older Black Friday deals. And why not, when monthly costs start well under a fiver? On this page you'll find links to the best SIM only deals currently available in the UK.

SIM only deals are usually the best option for those people who are out of contract but want to wait a while before they upgrade, or for others who have bought a phone outright and want a cheap SIM only deal to use with it. If your plan is up and you don't want or need a new phone, SIM only is your best bet.

Luckily for you, SIM only deals are very competitive at the moment, so there are a lot of great options as the networks compete on price. We'll start with our price comparison chart, where you can find the outright best deals, and underneath that you'll see some of the best SIM only deals that we recommend from multiple networks. Scroll on down to the bottom to find our extensive list of coverage checkers for every network too.

The best SIM only deals of the week are:

These are the deals we recommend most highly. We try to pick out a deal for everyone, whether you're after the cheapest possible option or the best balance between allowance and cost over one-month and 12-month SIM only deals.

1. The absolute cheapest SIM only deal out there

ID sim only deals

iD Mobile | 1 month contract | 250MB data | 250 minutes | 5000 texts | £4 per month
This is the cheapest SIM only deal currently available in the UK. If you just need to keep a phone up and running for occasional use, this is a good option. Clearly 250MB is not much data at all so you'd be advised to either keep mobile data switched off or else be careful what apps are updating in the background. BUT WAIT, CHECK OUT THE NEXT DEAL FIRST!

If you're looking for a super cheap SIM only deal but don't want to limit yourself too much with data, 1.5GB for £5 is the best option out there right now. Especially given how freely Wi-Fi is available outside of the home nowadays. You'll still be able to access emails, browse the net and casually check Facebook and stay under the limit. And as it's a 30-day SIM only deal, you can change your mind and cancel at any time.

Vodafone | 12-month contract | 25GB data | Unlimited calls and texts | 12 months of Sky Sports mobile, Now TV or Spotify | £25 per month
Vodafone's deals have been a bit pricey of late but we think the extras are well worth a look here. In addition to the massive 25GB of data, you get to choose between Sky Sports mobile, Now TV or Spotify for 12 months of free access. There's 4GB of roaming data too!

6: The best unlimited data SIM only deal

three deals

Three | 12 month contract | Unlimited data | Unlimited texts | 200 minutes | £24 per month
Sometimes, you've just gotta have all the data. Netflix marathons, epic Pokemon Go quests, constant Spotify tunes, this all you can eat data bundle is ideal for the serious mobile user who never needs to worry about poxy thing like data allowances or Wi-Fi. Shame about the comparatively low minutes offered, but how often do you use your phone as a phone nowadays? At least there's a £30 cashback incentive to claim.

The best SIM only deals on EE

EE's SIM only deals come with double-speed 4G
If you want a cheap SIM only deal, EE is most certainly not the network to go for. But don't discount it entirely, because if you already own a good smartphone and you want to pair it with the fastest network in the UK with a SIM only deal, you can do that. EE's SIM only deals all come with EE Extra 4G, which means they work with EE's super-fast double-speed 4G network, rather than with its single-speed 4G network. The 12-month EE SIM only deals often come with additional extras like three months of BT Sport or Apple Music for free.

three deals

The best SIM only deals on Three

Three's SIM only deals with unlimited data
Three is still the only network that offers all-you-can-eat / unlimited data as an option. That's not as impressive as you might think because other networks offer large allowances too. But if you want the absolute security of knowing you can never be charged if you go over your data allowance, these deals are brilliant and they offer good value too - particularly if you're a heavy data user. The all-you-can-eat data plans come with in a few different guises - with the price changing according to how many minutes you require. There are some Three deals without unlimited data that you may want to consider too.

A reliable network with great coverage
We've browsed all of the SIM only deals available on the O2 network, and they're not great compared to the competition for bundles including the usual 1-16 GB of data.

Freedom Pop is trying something new - offering contracts for FREE. The catch being that you only pay if you do over the allowances of your bundle or opt for a larger deal. The prices for doing so vary, so be sure to take a look at the small print. It seems that they feature a different offer each week, but seeing as you can cancel at any time, they may be worth a look.
