What is an eSIM

An eSIM, or embedded SIM, is a digital SIM you can use to activate a mobile plan without a physical SIM card.

It’s built into your device, so you can change networks and manage plans easily.

How eSIM Works

eSIM technology uses a small chip built into your device that can be set up remotely to connect to various mobile networks. Check device compatibility

This modern approach adds flexibility and eliminates the need to change physical SIMs when travelling or switching providers.
