An eSIM is like a digital SIM card that’s already inside your mobile device. It works just like the traditional SIM card you’re used to, but you don’t need a physical card to use it. Instead, it’s pre-installed in your device, and you can activate it by adding a digital “eSIM profile” from your chosen mobile operator.

Think of it as the next generation of SIM cards. Many modern devices, including iPhones, iPads, Google Pixels, and more, now come equipped with eSIM technology. This means you can easily switch between mobile carriers without needing to physically swap out SIM cards.
