What is the EID and why does it matter?

The EID (Embedded Identity Document) is a unique 32-digit serial number assigned to the eSIM module in your device. It is required by carriers to identify your specific hardware during the profile provisioning process.

How does 5G SA affect eSIM performance?

5G Standalone (SA) utilizes a dedicated 5G core network, resulting in significantly lower latency and higher security. Modern eSIM profiles are designed to support SA protocols, ensuring maximum throughput on compatible networks.
