NEW YORK – Three of the nation’s largest cellular phone companies have reached a deal with 32 states, including Maine, that requires them to be more upfront with customers in their advertisements and service plans.

Verizon Wireless, Cingular Wireless and Sprint PCS will be required to provide more detailed coverage maps to consumers, give customers a two-week grace period to end service without penalty and offer full disclosure of service contract rates and conditions. Their marketing also must be more specific about the costs and limits of services.

“Under the agreement, consumers will have a trial period to find out if they have wireless service where they live, work and play,” said Tennessee Attorney General Paul Summers.

The agreements end investigations in the participating states that focused on allegations of misleading advertising and a lack of disclosure on rates, terms and conditions, said Colorado Attorney General Ken Salazar.
