How is SMARTY different from pay as you go?

It isn’t, really. If anything, we believe it’s a better deal – and the experts agree.

On traditional PAYG plans, you stock up on credit and away you go. With SMARTY, you buy monthly plans in advance – which you can renew, pause or cancel at any time.

The flexibility of a PAYG SIM. The benefits of a contract.

If you go for one of our Data Discount plans, you get money back on the data you don’t use – instead of being wasted, it’s turned into credit towards your next month’s plan. But if you like to have loads of data, our 30GB, 200GB and Unlimited data plans offer just as much value.

With all of our plans you get unlimited standard UK texts and calls, and it’s super easy to add more data if you need it. So, there’s nothing to worry about.

Extra data at £1 per GB

At SMARTY, we believe in data add-ons at fair prices. 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 extra data when you really need it.

Our add-ons also never expire – as long as you have a live pay-monthly SIM , your data is there for you to use.

Go mobile

SMARTY isn’t just for phones. Our SIMs also work with tablets and mobile broadband devices like dongles and WiFi routers. Simply pay for your plan, pop your SMARTY SIM in, and you’re good to go.
