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.

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.
FAQs
All our SMARTY SIM cards are free to order. The only thing you have to pay for is the data plan you want. This is paid in advance to avoid any unexpected bills from going over your usage allowance. To use our free SIM cards you’ll need an unlocked SIM free phone. Speak with your current network provider if you need your phone unlocked.
You can order a free SIM card online from our website or via the SMARTY app. Alternatively, you can pick up a SIM card from larger supermarkets or independent corner shops, but there may be a charge.
Although SMARTY is primarily an online provider, you can pick up our SIM cards in large supermarkets and independent corner shops. However, you may have to pay around £1, if you pick one up in-store, but they are completely free if you order them from our website.
