SMARTY hidden 14GB for £8 SIM only deal: order via this link

We've got an exclusive deal for our readers with SMARTY that gets you the most data we've ever seen for £8 a month. Here's how to get it. SIM Sherpa is your trusty guide. Last updated: 13th January 2021.

What you get

The most data ever for £8 a month on any network
 (5/5, deal rating - full network review here)

We've been tracking SIM only deals on UK mobile networks since 2014 and we've genuinely never seen a provider offer so much data for the price, as SMARTY are with this deal. It's genuinely absurd.

The offer only lasts until 26th January 2021 and you have to use the hidden link to get the extra 4GB, which lasts your first 12 months with SMARTY.

The 14GB data is an exclusive offer that SMARTY have sent to comparison sites like us to share with our readers. If you just go to regularly, the best you'll see is 10GB for £8 - with no extra data.

But if you hit any of the deal links on this page (like this one here) ahead of the offer's 26th January 2021 expiry, SMARTY will add 4GB to your data allowance every month for 12 months (it returns to 10GB after that).

That doesn't mean this is a 12-month contract. It's not. It's still on a 1-month rolling plan only. So you're free to change plans every month or even leave SMARTY altogether, if a better deal comes along elsewhere.

And if you've not been on SMARTY or Three before, that short plan length means you can basically try them risk-free. If you like it, you've got a bargain amount of data. If you don't like it, you're only £8 worse off and you can leave straight away.

In our full SMARTY network review, we give them a good rating. We like their low prices and flexibility most. And their data discounts plans are a nice benefit (though this deal doesn't pay you anything back).

The 4G coverage in larger urban places is as good any mobile network and SMARTY's typical 4G download speeds between 20.39 Mbps and 22.4 Mbps (independent testers Speedtest and Opensignal's measurements of Three) are very healthy.

You even get some more advanced network features nowadays on SMARTY like WiFi calling and 4G calling (VoLTE) to keep your phone connected in more places than ever before, particularly indoors.
