FAQs

How do Big Bundles work?

Just top up the right amount for your chosen bundle each month to get your allowance. You'll be able to rollover your data at the end of the month.

Big Bundles last for a month and renew automatically on the same day each month, if you've got enough credit. If you don't, you'll be charged at our Big Bundles standard rates until all your credit's gone. You'll get your bundle allowance back when you top up enough credit again. Big Bundles terms apply.

How do International Big Bundles work?

Just choose your bundle and top up the right amount to get your allowance. It’ll last for a month and renew automatically if you’ve topped up enough credit. Select the £10 International Big Bundle with inclusive minutes to the UK and 29 destinations, or the £20 Premium International Big Bundle with inclusive minutes to the UK and 48 destinations, plus 250 extra minutes to call Nigeria, Pakistan and South Africa. You’ll get discounted international rates if you’ve used up your allowance or if you’re calling a destination that’s not included in your allowance. You must keep your bundle active to continue accessing the discounted international rates. And you can roll over your unused data every month. If you have a £10, £15 or £20 UK & International Bundle, see here for inclusions.Terms apply.

There is a minimum top up of £10 on the £5 Big Bundle, how does this work?

A £10 minimum top up is required for all Bundles, including on the £5 Big Bundles. When you've topped up, we'll automatically swap your credit for your Big Bundle, which will last for one month.

Any out of bundle charges incurred will be deducted from your credit so that means you'll need to top up £10 to activate your £5 Big Bundle again if you have used any of your credit before your Big Bundle renewal date.

If you do not incur any out of bundle charges, you will still have £5 available credit and your £5 Big Bundle will automatically renew in the following month.

How do I claim £10 free credit?

You can claim £10 free credit when you buy any Big Bundle. To claim your credit, text FREE10 to 21500 within 28 days of ordering your sim.

Will the sim fit my phone?

Our sims fit all devices.

What happens if I don’t use my phone for long periods?
