What is eSIM: Everything You Need to Know

eSIM, short for embedded SIM, is a technology that allows users to connect to mobile networks without using a traditional physical SIM card. Unlike conventional SIM cards that need to be physically inserted and removed from devices, eSIMs are built directly into the device’s hardware. The activation of eSIMs is done remotely by mobile network operators or pre-installed by device manufacturers.
