What is an eSIM (Virtual SIM)? π²
An eSIM, or embedded SIM, is a digital SIM card that is built into a device (e.g., a smartphone, tablet, or smartwatch) rather than being a physical, removable card. It serves the same fundamental purpose as a traditional physical SIM card, which is to identify and authenticate a device on a mobile network. However, eSIMs offer the advantage of being rewritable and programmable, allowing users to switch between mobile carriers and plans without having to physically change the SIM card.
eSIM technology has gained popularity in recent years and is particularly useful for travelers, those who frequently switch carriers, and for Internet of Things (IoT) devices that require remote provisioning and management. It simplifies the process of managing mobile connectivity, offering greater flexibility and convenience to users.
