Travelling without paying extortionate roaming fees is now possible thanks to eSIMs. In this guide we explain what an eSIM is, how it works, whether your phone is compatible and how to choose the best plan for your trip.

What is an eSIM?

An eSIM (embedded SIM) is a digital SIM card built directly into your smartphone, tablet or smartwatch. Unlike a physical SIM, you don't need to insert or remove any card: everything is managed digitally.
