Communications Sub-Module: ESIM
 

Overview
 

The ESIM (eSIM) sub-module is responsible for managing all electronic SIM card numbers within the Communications system. It provides a centralized interface to add, maintain, assign, and track ESIMs across team members and client communication packages.
 

This module ensures proper organization of ESIM resources, supports team member accountability, and integrates with external telecom APIs to verify ESIM connections and usage status.
