All the data you need for less
No ties. It’s the SMARTY way to pay.
With no credit check, no contract (so you can cancel at any time), and the flexibility to add more data when you need it, our no contract SIM only plans offer all the flexibility of a pay as you go SIM.
They can also be set to automatically renew – so you can enjoy the convenience of a pay monthly contract – without the contract.
Extra data at £1 per GB
If you run out of data during the month, an add-on will cost just £1 per GB. This is the same amount you pay for data in your usual plan, so you’re not getting stung for buying additional data when you really need it.
Plus, our add-ons never expire – so as long as you have an active no contract SIM card, your data is there for you to use.
The best no contract SIM for your tablet, dongle and more
Our no plan SIM cards aren’t just for phones. They also work great for tablets and mobile broadband devices like dongles and WiFi routers. All you need to do is choose your plan, pop in your SIM, and you’re ready to go.
Unlimited UK standard calls and texts
Once you’ve activated one of our no contract SIM cards, UK standard calls and texts are completely unlimited. So you can call your friends and family as much as you want.
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.
