What is an eSIM?

An eSIM is a digital SIM card, built into most modern mobile handsets eliminating the need for a physical card.

At home

An eSIM is set-up by downloading data from a mobile provider, often through a QR code. It’s a faster, easier way to connect to a mobile network or switch to a new provider, without needing to go to a store or wait for a SIM card to arrive by post.

When travelling

An eSIM roaming plan allows you to use a mobile service abroad without a physical SIM card. Once purchased installing and activating an eSIM involves scanning a QR code or manually downloading the eSIM via the device settings, to connect to a local or international mobile provider.
