What is eSIM?
An eSIM is an “embedded SIM card” which is built into a mobile device’s hardware. It does everything you’d expect a plastic SIM card to do, but 100% digitally.
These reprogrammable chips allow you to download data plans on the go and connect easily to mobile networks, eliminating the need for local SIM cards when travelling abroad. If you’ve ever spent ages wilting in a mobile phone shop after landing or trying to connect to patchy, insecure Wi-Fi, you’ll know that’s a really big deal.
