Data discount plans

Get money back for unused data

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.

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.
