All the data you need for less

The flexibility of pay as you go. The convenience of a contract.

When you choose an Unlimited data pay as you go SIM you can set it to automatically renew – so you get all the benefits of a pay monthly contract.

But, with no credit check, no contract (so you can cancel at any time), and the flexibility to add more data when you need it, you’ll also enjoy the freedom of a pay as you go SIM.

Is it really unlimited?

Sure is. There are no speed restrictions or data caps on our Unlimited data SIM only deals, so you can stream, scroll, browse and play to your heart’s content.

The perfect fit for tablets, dongles and more

Our Unlimited data SIM cards also work with tablets and mobile broadband devices like dongles or WiFi routers. Just pop in your SIM card, and you’re ready to go.

Unlimited UK standard texts and calls

Data isn’t the only thing that’s unlimited at SMARTY, all UK standard calls and texts are too. So it’s easier than ever to stay connected with the people you care about.
