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.

SIM with wings

Only pay for what you use

Get money off unused data

Whatever monthly 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

£5 is the base monthly rate included in the price for all plans, covering service costs plus unlimited texts and calls if you’re using it on a phone. The rest is for data.

2

If you’ve got any data left after using your plan, we convert it to credit and discount if off your next month’s bill – at £1.25 per GB, the same rate you paid in your plan.

So, if you’ve got 3GB of unused data, you’ll get £3.75 off your next month’s plan. Lovely. We even calculate using remaining MBs, not GBs.

Don’t get stung for extra data
Extra data at only £1.25 per GB

All data 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.

Data add-ons
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.
