The wireless carrier T-Mobile plans to become the third provider to boost its signal in Harpswell by installing equipment on a cell tower at the town-owned George J. Mitchell Field, a town official said.

T-Mobile plans to have its equipment up and running by late summer, according to a May 20 memo from Harpswell Town Administrator Kristi Eiane. “The Town will know when that is the case, since Blue Sky Towers will pay the Town of Harpswell a revenue share amount of $35,000 pursuant to our lease agreement,” Eiane wrote.
