What is an e-SIM?

An eSIM (embedded SIM) is a digital version of a traditional SIM card that’s built directly into your device. It allows you to activate a mobile plan instantly - no need to insert or swap physical cards. With an eSIM, you can easily switch between carriers, manage multiple phone numbers, and stay connected wherever you go.

Most modern smartphones, tablets, and smartwatches already support eSIM technology, and activation takes just a few simple taps. It’s the easiest and most flexible way to get connected when traveling or changing providers.
