Don’t get stung for extra data
Extra data at only £1 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 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.
Data-only SIM cards are perfect if you’ve got a tablet with SIM capability and you want to get online wherever you are. You can purchase a SMARTY SIM with varying levels of data – from just 1GB to Unlimited. Plus, you can even get money back on what you don’t use when you pick one of our Data Discount plans. While our SIMs are not technically data-only they are still compatible with tablets and mobile broadband devices. Unlimited calls and texts come as standard on all of our SMARTY SIMs, but you won’t pay extra for them and you don’t have to use them.
While every tablet on the market is likely to be Wi-Fi enabled, not all tablets let you insert a SIM card for 3G or 4G internet access. If your tablet does support SIM cards, then a SMARTY SIM is perfect for getting online. Our flexible plans offer anything from 1GB to Unlimited data and can be amended as and when you need them.
Most people are more than happy on 20GB of data a month. For that amount you can spend around 2 hours a day browsing the web and social media, 2 hours listening to music and one hour streaming your favourite shows. To put it into perspective, a 2019 study by OFCOM showed that the average person used 2.9GB of mobile data per month, and while that’s naturally expected to increase, 20GB shouldn’t leave you in much danger of running out. If you are worried though, SMARTY offer great value 30GB, 50GB and Unlimited data SIMs.
