Save with a Data Pack

Data Packs

If you use lots of data, buying a Data Pack instead of topping up can save you money.

  • Buy data up-front to get more value.
  • Data Packs last for 1 month.
  • Enjoy Unlimited minutes and texts for the whole month.
  • No ongoing commitment.

  • When one expires, you go back to using your credit like normal.
  • Buy Packs when you need them, or set up Auto-renewal.
  • You can buy 1 Data Pack per month.
  • If your data runs out, data Add-ons are available.

Your questions answered

What is a Data Pack?

A Data Pack allows you to buy lots of data up-front. This data is yours to use for up to 1 month and doesn't come out of your credit allowance.

Each Data Pack also gives you Unlimited minutes and texts for the whole month too.

Is this like a contract?

No, after a month the Data Pack expires and there's no commitment to buy another one.

You can go back to using your credit as normal, or buy another Data Pack for the next month. You can also set up Auto-renewal to buy a Data Pack automatically each month. You can cancel this at any time.

What happens when my data runs out?

You’ll still get your Unlimited minutes and texts for the rest of the month. But you’ll be charged our standard rate for any data you use, which will be charged to your existing cash credit.

You can only buy one Data Pack at a time, and you'll need to wait for one to expire before you can get a new one.

If you do run out of data…

If you use all your data before the end of the month, you can buy an Add-on to get extra. You can buy Add-ons using the Three UK app, or you can top-up your cash credit and pay for data at the standard rate.
