All the data you need for less

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

When you start a cheap SIM only plan with SMARTY, you can set it to automatically renew – so you get all the convenience 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 also enjoy all the flexibility of a pay as you go SIM.

If you have a SIM-free phone, our cheap SIM card is the perfect fit.

If you’ve got an unlocked SIM-free phone, ours are probably the cheapest data only SIMs you’ll find. Simply pop in your SIM, pick your plan and you’ll be connected in no time. Just follow the instructions on the pack we send you.

Our cheap SIM only deals are also great for tablets and mobile broadband devices like dongles and WiFi routers. All you need to do is choose your plan, pop in your cheap SIM card, and you’re ready to go.

Once you’ve activated one of our cheap prepaid SIM plans, UK standard calls and texts are completely unlimited. So there’s no excuse for not catching up with friends and family.
