Consolidation of Cellular Phone Plans

In October 2008, OIT completed an 18 month effort to consolidate the individual cellular phone plans used by agencies in the Executive and Judicial branches and Secretary of State's office. This consolidation allows agencies to take advantage of pooled minutes and for the state to realize a significant cost savings as well as receive enterprise level reporting.
