What is c3gEsn?
This read-only string reports the modem's Electronic Serial Number (ESN), a hardware identifier used on CDMA networks. An admin needs this identifier when provisioning cellular service with a carrier or when opening a support case, since carriers typically require the ESN to activate or troubleshoot a specific device on their network. For example, an admin replacing a failed cellular modem would read this object to record the new hardware's ESN and provide it to the carrier for reactivation.
