T3 is the UK's foremost expert on SIM only deals and we spend each and every week monitoring the market for the greatest new SIMO packages.

This is because that, while buying a phone on-contact can be a great option for many people, as it gets you brand new phones for very little spend upfront, if you can buy a handset SIM free then you get access to superb SIM only deals, which offer markedly better data, texts and calls allowances for significantly less money.

And this brand new Smarty SIM only deal is a great example of that, with the SIMO plan delivering 50GB of data each month, unlimited calls and texts, as well as no contract commitment (meaning you can leave at any time) for just £12 per month.

The price is a high point for the SIM only deal, as too its large amounts of data, however for us here at T3 it is the fact that it comes with a 30-day rolling plan that you can cancel at any time that is the cherry on the top of the SIMO cake. Find a better SIM only plan next month? Then you simply click a few buttons to cancel and you're free to upgrade elsewhere.

This SIM package will be ideal for anyone who is currently out of contract and is looking to go SIM only while not spending much at all each month. It doesn't deliver 5G data, and that is a consideration, but if you don't have a 5G phone or don't live in an area with 5G (still, depressingly, the vast majority of the UK), then this SIM plan will be ideal.

The full details of the Smarty SIM only deal can be viewed below:

Star Deal

SIM only plan from Smarty | 1-month rolling | 50GB data | Unlimited calls and texts | £12 per month
50GB of data each month for just £12, along with unlimited minutes and texts and, best of all, no long-term contract in terms of commitment is SIM only heaven. Ultimate walk-away freedom and buckets of data to burn each month is a big win in our eyes.

If you like the look of the SIM only deal above but feel you really need unlimited data, then Smarty also has an unlimited everything plan on offer, too. As with the deal above, this delivers only 4G and 3G data, so you don't get 5G, but you get unlimited amounts of it, as well as unlimited calls and texts, for just £20 per month. And, just like the SIM only deal above, this one also comes with no contract.

This plan will be ideal for anyone who doesn't have a 5G phone or who doesn't live in an area of the UK where there is 5G network coverage. And the beauty with it is, is that if the owner does then get a 5G phone or move to somewhere with 5G coverage, they can simply walk away from this plan if desired at any time. Before picking up another SIMO package that does come with 5G data.

SIM only plan from Smarty | 1-month rolling | Unlimited data, calls and texts | £20 per month
This deal gets you everything in unlimited quantities for just £20 per month. So that's unlimited data, calls and texts. It also has no contract commitment, either, with the plan just rolling over every month. That means you can walk away at any time and aren't tied to a long multi-year contract.View Deal
