ESN and UIMID Exhaust
Friday, March 7, 2008

The CDMA Development Group (CDG) hosted a live, interactive webcast on Friday, March 7, to discuss Electronic Serial Numbers (ESN) and User Identification Module Identifiers (UIMID) exhaustion, a critical issue currently faced by CDMA operators.

The webcast addressed all aspects of the migration from ESNs to Mobile Equipment Identifiers (MEID), and from UIMID to Extended User Identification Module Identifiers (EUIMID). This is an urgent issue because ESNs and UIMIDs are expected to be exhausted by the middle of 2008.
