what does esim stand for

eSIM stands for "Embedded SIM," which is a digital version of the physical SIM card. It is embedded within a device itself and cannot be removed like a traditional SIM card. The eSIM is a software-based version of a traditional chip-style SIM card, and it performs the same function as a physical SIM, but it is more convenient as it allows users to change providers or add coverage without making any physical changes to the device. An eSIM is typically provisioned remotely, allowing end-users to add or remove operators without the need to physically swap a SIM from the device. It is used in various devices such as smartphones, tablets, smartwatches, drones, and cars, and it offers benefits such as space-saving, remote programmability, and enhanced security compared to traditional SIM cards.
