Data SIM deals - tablets and mobile broadband
With a SMARTY SIM-only data plan, you pay for the data you use, not the data you don’t.
Switch to a simple SIM-only data plan
Perfect for tablets, dongles, WiFi routers and other mobile devices.
We’re SMARTY – the SIM-only mobile network that’s all about keeping things simple. Our monthly plans start from £6.25 and work with most mobile data devices: tablets, dongles, WiFi routers, laptops, games consoles and more. And you even get money off data you don’t use.

Fast 4G and 3G powered by Three
We’re powered by the expansive Three network, which means fast 4G or 3G for 98.3% of the UK population.
No long contracts, no ties
Simply pay for your first month up front, then on a rolling monthly basis. You’re free to pause or cancel at any time – no commitment, no hassle. Unlike some SIM contracts, you’re not tied in and there’s no surprise charges. Oh, and there’s no need for a credit check.
Only pay for what you use
Whatever monthly data discount plan you're on, you get credit for any data you don't use. We reckon this makes us one of the best deals around for SIM-only contracts.
£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 £1.25 per GB, the same price it’s charged at.
For example, if you’ve got 3GB of unused data, you’ll get £3.75 off your next month’s plan. We even calculate using remaining MBs, not GBs.
This means you only ever pay for what you need.
Don’t get stung for extra data
Extra data at only £1.25 per GB
All data discount plans are capped, so you’ll never accidentally overspend if you run out of data. But if you find you need any extra, it’s super easy to add more at a rate of £1.25 per GB.
Data add-ons also never expire. As long as you have a live, current SIM plan, it stays there. Forever. And ever.
Unlimited UK standard texts and calls
Our SIMs are also ideal for phones. Each plan comes with unlimited UK standard texts and calls included, and you don’t have to change your number when switching.
Check our 4G & 3G coverage
SMARTY connects to 4G network wherever it can. SMARTY is not compatible with 2G handsets.
No need to change your number
As soon as your SIM is activated you can port your number to SMARTY. You’ll just need a PAC code from your current network.
Adding data or credit
If you run out of data it’s £1.25 per GB - the same as it costs in your plan. To call an 084 or 087 number you can add credit in £5 increments. Add-ons never expire.
A bit about tethering
You can tether and hot-spot all of your data with no speed restrictions.
