Let's get started
1. Install your Three SIM card
Put your new SIM in your phone. If you need help with this, check your phone’s user manual. Once your SIM’s installed, we’ll text you your new number.
3. Top up your credit
Adding credit to your account is simple. It can be done on our app, by logging in to your account, or anonymously through your browser.
4. Choose how to use your credit
There are two ways to use Pay As You Go with us. You can either spend your credit at our normal rates, or exchange it for a Data Pack – a monthly bundle of minutes, texts, and data. Data Packs are great value for money and can be bought in-app.
Data Packs give you more
Make your money go further. Choose your monthly data, and get unlimited minutes and texts included. Plus, you can Go Roam at no extra cost. And there's no contract, so you can cancel anytime. Or auto-renew to keep it going.
