Vermont’s state auditor said he has found nearly $300,000 in savings in the purchasing and oversight of state cellphone services. Doug Hoffer said the state’s current system is decentralized and does not have consistent policies and procedures to ensure that resources are optimized. Hoffer said that in 2012, charges for 3,080 state-issued cellphones totaled about $1.6 million. But 9 percent of those phones were not used, and 20 percent had limited use. He said the little-used cellphones cost the state about $272,000. The audit also found that more than 5 million allowed voice minutes went unused, nearly half the total.
