This SIM only deal for £8 a month from Plusnet is the cheapest 3GB plan around

It's a well-known fact of life that Three SIM only deals are usually the best around if you're looking for a new SIM at the end of your mobile phone contract. But as we approach the sales bonanza that will be Black Friday 2017, other networks are trying to get a slice of the SIM only pie.
The latest promotional price from BT-owned Plusnet is an absolute corker. You can get its 3GB SIM only plan for just £8 a month from retailer Direct Mobiles. That's the cheapest price in the UK for a 3GB tariff, which is the sweet spot for a lot of users.
And because it's on a one-month rolling contract, you're not committed for a whole year like most of the best cheap SIM only deals. That means you have the freedom to ditch your SIM if you get tempted by a new iPhone X deal or the like in a few months' time. But this deal is only around for two weeks – you'll have to claim it by November 8.

Plusnet Mobile | 1 month contract | 3GB data | 500 minutes | Unlimited texts | £8 per month
We really like this Plusnet SIM only plan. For starters, the price is exceptional, and will mean a massive fall in monthly bills if you currently own a 2015 flagship phone on contract. With the vast amount of Wi-Fi spots available in the UK, 3GB should be enough for most users to freely stream, surf and download without exceeding your limit. And you don't pay a premium for a commitment-free one-month rolling contract.

Plusnet Mobile is now owned by BT, so it's keenly watched over by a company with phenomenal experience in the telecommunications arena. It's an MVNO – or mobile virtual network operator – which means it piggybacks off a bigger and more established network – EE in this case. So you get the benefit of the UK's fastest 4G network, without the cost of an EE SIM only deal.
As well as excellent 4G coverage you also get the benefit of Plusnet's 'Roam Like at Home', which lets you use your monthly plan allowances in any EU destination and a few extra countries to boot. We also like the network's Smart Cap, where you can set a limit for the amount you’re happy to spend above your monthly plan price on chargeable services. That means things like calls to premium numbers, calls to 0845, 0844 or 09 numbers, any charges that may apply while using your phone abroad, or making international calls.
Need more than 3GB of data, or just want to go with a name that's a little more familiar? We've picked out another three superb SIM only plans that are well worth a look. And if you want to see everything that's available and tailor a tariff to your needs, then you can use the interactive price comparison chart on our best SIM only deals page.

Three | 12-month contract | 12GB data | Unlimited calls and texts | £12 per month
This is one of the very best SIM only deals out there – and it's easy to see why. A mere £12 a month for a very healthy 12GB of data is tremendous value. This deal hits the sweet spot between plenty of data and cheap monthly bills, and we love it.

Vodafone | 12-month contract | 20GB data | Unlimited calls and texts | £11.75 per month (after cashback)
There's a bit of effort required for this one, but we reckon it's worth it. The huge £99 cashback offer means that the effective monthly payments come in at under £12 a month, for which you get a massive 20GB of data. But to take advantage of the savings you have to submit a bill every couple of months to claim your cashback.

Three | 12-month contract | 30GB data | Unlimited minutes and texts | £17 per month
Yep, it's Three again. But even a quick glance at this incredible big data deal is enough to tell you why we're repeating ourselves. This exceptional 30GB data deal won the Best Phone Deal award at the Mobile Choice Awards 2017, thanks to the staggering amount of data for well under £20 per month. A brilliant bargain.
