Get money off unused data
You never know how much data you're going to need. But with SMARTY's data discount plans, you pay for the data you use, not the data you don't. So what's the deal? How does it work?
£5 is the base monthly rate included in the price for all data discount plans, offering unlimited standard UK texts and calls. The rest is for data.
At the end of each month, we take any unused data you have and discount your next month’s plan - at the standard rate of £1 per GB, the same price it’s charged at.
For example, if you’ve got 3GB of unused data, you’ll get £3 off your next month’s plan. We even calculate using remaining MBs, not GBs.
This means you only ever pay for what you need.
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 pay-as-you-go 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 twist is, you get money back on data you don’t use – instead of being wasted, it’s turned into credit towards your next month’s plan. You also 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.
4G coverage across the UK
We’re powered by the expansive Three network, which means fast 4G or 3G for 99.5% of the UK population (outdoor).
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.
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.
SMARTY connects to 4G and 3G network wherever it can. SMARTY is not compatible with 2G handsets.
