Pay & Go sims

Free sims for phones and tablets

  • Keep your device and choose a flexible tariff with all of our perks included.
Choose your free sim

Choose a £10, £15 or £20 Big Bundle tariff. Top up this amount each month and we'll automatically exchange your credit for the minutes, texts and data allowance of your chosen bundle.

There are no contracts with Big Bundles. They last for one month and renew automatically on the same day each month - but only if you've got enough credit to cover the payment. If you don't, choose when you want to top up again and you'll get your bundle when you do.

Plus, if you have any credit left, you'll still be able to call, text and use data at our standard rates until it's all gone.
