Cheapest SIM-Only 1GB data deals in the UK right now

We round up the best value SIM-Only mobile deals which offer 1GB of monthly data, right now in the UK.

If the thought of a pricey 24-month phone contract makes your throat constrict with fear, like an invisible noose around your neck, you’ve come to the right place. These SIM-Only deals with a decent 1GB of data could be for you.

What is a SIM-Only deal?

Exactly what it sounds like. A SIM-Only deal gives you nothing but the SIM card, to plug into whatever mobile device you have at hand. This will come with a set number of minutes, texts and data allowance each month.

SIM-Only comes in 12-month or even just 30-day contracts, so you’re not tied in for the long-haul. SIM-only deals can also be super affordable too, saving you lots of cash compared with a monthly contract.

You can keep using your old phone if you like, or buy a new handset outright and then try a SIM-only deal, which will often save you cash in the long haul. The tough part is paying for that phone straight off, either by saving up, or using an interest-free credit card.

Is 1GB of data enough?

The amount of data you’ll need is of course a big question and a massive concern for some. As a rule, 1GB is good enough for basic use – emailing, messaging and the rest. Check out our ‘how much data do I need‘ feature for more info. We’ve also compiled a handy guide to check how much data you’re currently using on your smartphone.

If you want to go really cheap, you can get Sky Mobile’s new 500MB contract for just £5 per month, including unlimited calls and texts. But most people need a little more data than that to get by and probably don’t mind paying more than the price of a pint for the peace of mind each month.

Here are some of the best affordable SIM-only deals in the UK, all of which offer you a decent 1GB of free data per month.
