An eSIM is a SIM card that is embedded in a mobile device and can connect you to any operator offering eSIM services. Furthermore, the e-SIM works the same way as a traditional SIM card, but you don’t need a physical SIM card to use it. It is actually pre-installed in the device and you can activate it by installing the “eSIM profile” of a new operator. With an eSIM-compatible device, you can easily install an eSIM profile (provided by operators/carriers) to be able to buy an eSIM data plan when you need it, on the go. Plus you can use multiple operators and subscribe simultaneously to several data plans to suit your needs.
