Download the Three app

Get a Data Pack or Top-up
You’ll need a Data Pack or Top-up to start using your SIM.
If you’ve bought your SIM with a pre-loaded Data Pack or Top-up, it’ll be ready to use straight away. If not, you can top up online or on the Three app.
Adding data
Data Packs
Make your money go further. Choose as much monthly data as you want and get unlimited minutes and texts included. And with Auto-renew Data Packs, get the same amount of data every month, save 10%, and get up to 50GB extra data.
