How the Three eSIM works

1. Choose your plan and pay with PayPal or card.
2. We email your eSIM QR code, usually within minutes.
3. On your phone open Settings → Mobile data → Add eSIM and scan the QR code.
4. Your UK number is ready to use – no plastic SIM, nothing posted.

Your phone must support eSIM and be unlocked. Each QR code can be installed once, on one phone.

Keeping your Three number

Three needs at least one chargeable use every 180 days – a top-up counts. Once you have the SIM you can top it up any time with our Three top up vouchers, sent by email in minutes – handy if you live abroad and want to keep your UK number.

Go Roam: use your bundle abroad

Each bundle includes a Go Roam allowance (shown in brackets above) that you can use in 71 destinations at no extra cost – including the EU, Switzerland, Norway, Iceland, the USA, Australia, New Zealand, Hong Kong, Singapore, Vietnam, Israel and much of Latin America. You can call and text UK numbers from these places too. Go Roam is for holiday use only; full list and terms at three.co.uk/go-roam.
