Future-Ready, Secure, and Redundant Network Access for Mission-Critical Applications
An Embedded SIM (e-SIM)—also known as an Embedded Universal Integrated Circuit Card (e-UICC)—is a soldered, non-removable SIM that performs the same core functions as a traditional plastic SIM card but with enhanced durability, security, and remote management capabilities. Unlike conventional SIMs, e-SIMs support over-the-air (OTA) provisioning, enabling dynamic network switching without physical intervention.
