Your questions answered
What’s a Data Pack?
A Data Pack lets you exchange your credit for a set amount of data with Unlimited minutes and texts. If you use a lot of data, they’re better value than our standard Pay As You Go rates. Data Packs last 1 calendar month and you can change them monthly to suit you.
What happens when my data runs out?
You’ll still get Unlimited minutes and texts for the rest of the month, but you’ll be charged our standard rate for any data you use. This will be taken from your existing credit.
As you can only buy 1 Data Pack at a time, you'll need to wait for it to expire before you can get a new one.
Are Data Packs like a contract?
No. Data Packs only last a month and there’s no commitment to buy another one. You can go back to using your credit like normal, or buy another Data Pack for the next month. You can even set up auto-renew so you’re always topped up.
What if I need extra data for the rest of the month?
Use the Three Pay As You Go app to buy a Data Add-on, or use your credit for data at our standard rate.
What is auto-renew bonus data?
When you auto-renew, a £10 8GB Data Pack becomes 10GB and a £15 25GB Data Pack becomes 30GB. Plus you’ll get the added convenience of getting the same Data Pack automatically each month.
How do I get auto-renew bonus data?
You can activate auto-renew on our app or My3 when you buy a Data Pack. If you already auto-renew and want to get this promotion, it’s easy. First, turn off auto-renew and wait for your Data Pack to expire. Then select a promotional Data Pack and reactivate auto-renew.
