I love my SIM-only rolling contract. It delivers a huge amount of data, unlimited calls, and best of all, there's no commitment. If your contract is up or you're looking to switch contracts, then you'll want to know Smarty is offering a double data upgrade that gets you 80GB for £10 a month.
This is one of the huge benefits of going with a rolling contract: if I want more data or find a better deal elsewhere, then I can jump over without any hassle at all. But, with 80GB of data, that's enough to cover all your app downloads, video watching, and social media browsing.
But, if that's not enough, a 200GB SIM will only cost you £15 per month. This is the perfect solution if you're streaming shows and movies with your mobile data.
These SIM cards will work on your existing handset, or if you're thinking about buying one of the new Samsung Galaxy S26 phones, then they're compatible too.
Today’s best cheap SIM-only deal
Smarty 80GB for the price of 40GB: now £10 per month
An incredible double data upgrade from one of the most popular SIM-only providers in the UK. With 80GB of data, you'll have enough to stream videos and browse, surf the web and enjoy all the social media you want with ease. This plan can be cancelled or changed at any time with no annual price rises or credit checks.
Smarty provides simple, honest, SIM-only plans, including eSIMs. Every plan is good value and so flexible, so it can be changed or cancelled at any time. If you've never heard of Smarty, the company also utilises Three's network, which means they're able to deliver a reliable service.
My SIM plan includes 10GB, which allows me to watch videos, download apps, play games, and browse the web. The 80GB package that Smarty is offering here is therefore more than sufficient to cover most people's needs.
There's also EU roaming included up to a fair 12GB limit, which I'm sure will be sufficient for most holiday trips. To top it all off, the plan includes unlimited calls and texts as well as WiFi calling.
