Stay connected across the UK and Europe the moment you land. No physical SIM, no card swapping. This Three (3) network eSIM gives you high-speed data, unlimited local calls and texts, and mobile hotspot across UK & Europe. Your QR code is emailed to you within minutes of ordering, so you just scan, install, and get online.
Powered by Three UK, your full data allowance is usable in the United Kingdom, with a generous roaming allowance for when you travel on to Europe and beyond. It is ideal for frequent travellers and multi-country trips, giving you one eSIM instead of a new SIM in every country.
