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.

SIM with wings

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.

  1. 1

    £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.

  2. 2

    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.

  3. 3

    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.

Data add-ons

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 calls texts

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.
