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.
Get started with a cheap SIM only contract
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.
A cheap SIM deal for your tablet, dongle and more
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.
Unlimited UK standard calls and texts
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.
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.
Already got your free SIM? Log in to your account and tap “Activate SIM” to begin your billing month and start using your data, calls & texts. Activation should happen in just a few minutes, but could take up to 2 hours. We’ll send you an email and a text to your SMARTY SIM when your SIM is activated. If you want to keep your old number, you can request a PAC code from your current provider.
