State of Phone Justice 2022: The problem, the progress, and what's next
How much should it cost to stay in touch with Mom or Dad when they're locked up? We gathered data showing that while some jails and their phone companies provide calls for as low as 1 or 2 cents a minute, the vast majority charge 10 times that amount or more. Data from 50 state prison systems and over 3,000 local jails and other facilities show that families are paying exorbitant rates, while companies find new ways to price-gouge them through an expanding array of non-phone products.
