This first depends on where yopur inmate is incarcerated. InmateAid has a listing of the correct phone service matched to every facility. Remember, there are no replacements for the services at the prison or jail, the company with the contract is running the phone system with competition. They get to make the rates. That is where InmateAid comes in. We have done the hard work of knowing what phone line gets the lowest price.
It used to be that local lines were the lowest. NOW, it's confusing, different and expensive. Trust InmateAid to get the right number for the biggest savings, if we cannot save you money, will not issue you a number.
