eSIM

An eSIM (embedded SIM) is a built-in digital SIM card inside a device, eliminating the need for a physical SIM card. It securely stores your carrier information and allows you to activate or switch networks digitally, often by scanning a QR code or downloading an app. This makes devices more compact, durable, and flexible, as you can change carriers or plans without swapping physical cards. eSIMs are used in smartphones, tablets, smartwatches, and IoT devices, enabling easier connectivity management and supporting the trend toward more integrated, seamless technology.
