eSIM

eSIM, or embedded SIM, is a digital SIM card that is embedded within a device, such as a smartphone, tablet, or wearable device. Unlike traditional SIM cards that are physical cards inserted into a device, eSIMs are programmable and can be activated remotely by a mobile network operator. This allows users to switch between carriers without needing to physically change a SIM card. eSIM technology enables a more streamlined design for devices by eliminating the need for a SIM card slot and provides greater flexibility for users who travel or wish to use multiple networks. eSIMs support multiple profiles, allowing users to save several carrier subscriptions on a single device and switch between them as needed via software settings. This innovation enhances connectivity and convenience in managing mobile services.
